Connecting a Chinese touch switch. Livolo connection diagrams

Management idea lighting fixtures through touch switches not new, similar switches or light switches were produced in the last century. But the dimensions of such devices were significantly larger than standard ones, which caused problems during installation. It is also worth noting that the cost of the first touch switches was quite high; naturally, this did not contribute to their popularity. With the development of technology, the situation has changed radically, and today capacitive, infrared and remote switches are in stable demand.

Design and operating principle

Despite the variety of models of touch communicators, most of them have a standard design consisting of the following elements:

  1. Housing made of heat-resistant plastic (see A in Fig. 1). The dimensions of the structure allow installation in a typical mounting location of a conventional switch.
  2. Electronic unit (B), it includes a power adapter and a semiconductor switch control circuit.
  3. Board with capacitive sensors (C).
  4. The front panel (D), as a rule, is made of quartz glass; budget models may use other materials.
Figure 1. Legrand six-key wall switch

Now we will tell you how such devices work. The electronic unit monitors the state of the sensor. When you touch a certain place on the front panel of the switch with your hand (it is marked accordingly), the capacitance of the sensor changes. The electronic unit detects this and changes the state of the contactless semiconductor switch, which opens or closes the electrical circuit.

Scope of application

Initially this type The switches were planned to be used to turn on/off lighting, but the design turned out to be so successful that the scope of its application has expanded significantly. Today, most modern household appliances have touch controls; examples include kitchen stoves, hoods, microwaves, etc.


The only limitation on connecting to touch switches is the power of the equipment; its permissible parameters are indicated in the device passport.

Additional functionality

Modern technical base has made possible installation microcontrollers into the electronic control unit for the touch switch, made it possible to significantly expand the functionality of the switches and allowed them to fit into the concept of a smart home. Such switches can be controlled by voice, infrared or radio remote control, smartphone via WI-FI or a programmable timer.


The touch switch can be connected to the smart home system and controlled using a mobile phone

Touch switches can be used in conjunction with sensors that respond to motion or light levels. In the first case, such devices turn on a lamp, table lamp or other lighting fixtures when someone enters a room, such as a bathroom. With the second implementation option, the light will turn on at a low light level.


Sesoo Triple Touch Switch and Motion Sensors

Some manufacturers, for example, Livolо, produce touch switches with a dimmer function or that control combined sockets, to which almost any household appliance can be connected.

Advantages of capacitive switches

Speaking about the advantages of this type of switches, the following qualities should be noted:


Now briefly about the shortcomings. First of all, it is necessary to note the difference in cost with conventional mechanical switches, but it has become significantly less than 10-20 years ago. The price of inexpensive Chinese touch models today is much cheaper than mechanical switches famous brands, such as GTS or Electronics.

Sometimes LED lamps connected to touch switches flicker. This may be due to both the low quality of the lighting sources themselves and the low-cost switch models. The problem can be resolved in two ways:

  1. Use products from well-known brands (Jazzway, Panasonic, Sapphire, Funry, LightaLight, Tronic, Sesso, etc.).
  2. Connect a 0.1 uF 630 V capacitor in parallel with the LED lamp.

Connection

The installation of touch switches is practically no different from the installation of conventional built-in and surface-mounted mechanical switches. You can read more about this process on the pages of our website. Let us remind you how to do this using the example of the kg020gs model from the manufacturer FD Electronics.

Connection algorithm:



Figure 8. Second and third connection stages

Some manufacturers, for example, Livolo, produce pass-through switches for 220 V (their connection diagram is shown in Fig. 9). With their help, you can control lighting from several places.


Figure 9. A clear example of how to connect several feedthroughs touch panels contact

Each of these switches controls the lighting in the room from different locations. The concept involves using a main switch and one auxiliary (or more). On the main devices there are three terminals, the phase is connected to one, the zero is connected to the other, and the control conductor is connected to the third. Accordingly, such contacts are marked as: L – phase, N – zero and Com – control wire. Assistive devices

Secondary switches are connected through two terminals: N – zero and Com – control contact. Marking different manufacturers may vary, so it makes sense to study the instructions. An example is the connection diagram for the electronic dimmer et0802193e, or its analogue tt6061a, which can be controlled with a light touch of your hand.


Selecting a touch light switch

Before purchasing a device, you need to determine its functionality. To do this, the following criteria must be taken into account:

  1. Power of connected equipment and its connection diagram.
  2. Execution corresponding to the type of wiring.
  3. Operating conditions (if installation is planned in the bathroom, then a device with moisture protection is selected).
  4. Opportunity remote control(remote control or smartphone).
  5. Compliance of the design with the interior of the room, etc.

Having decided on the main tasks, you can begin to select a manufacturer. Naturally, you should give preference to well-known brands whose products are reliable. But it is necessary to take into account the presence in the model range of switches of devices with necessary functions. For example, Delumo has devices controlled by a radio remote control, and Sonoff specializes in Wi-Fi devices, Capsens Domuns Line lamps are “tailored” only for their touch switches, etc. There can be many nuances, so we recommend that you study the various options in detail.

Based on practical experience, in addition to well-known brands such as Legrand, we can recommend Vento Electric, Wemmon, Fanri, Merten, CGSS, Steu, Schneider, Ariston, etc.


MakeGood Classic wireless touch switch with remote control and backlight

We recommend monitoring online reviews where ratings are published. the best manufacturers. Selection criteria are made as per model range manufacturers, taking into account functionality and cost, and other indicators.

Refinement of standard devices

Many people are not happy that the touch zone on the panel is quite small, and to record a signal you need to touch it in the indicated place. Let's give an example of how you can increase the area of ​​indirect surface contact.


You should take the wire and carefully solder it to the place where the signal is supplied from the sensor on the touch board (for this you need to study schematic diagram devices). The connected wire is laid around the perimeter of the housing. As a result, such a frame will make it possible to trigger the sensor when touching the front panel without amplifying the signal level.

It should be noted that such an improvement will void the manufacturer's warranty.

DIY touch switch

For those who like to work with a soldering iron, we can recommend several circuits of touch switches that will be easy to assemble with your own hands. Let's start with a simple field-effect transistor circuit, this is exactly the principle that was laid down in the first touch devices.


Designations:

  • Resistances: R1 - 10..15 kOhm (must be selected for sensor response), R2 - 3...5 MOhm.
  • Capacitors: C1 – 1000 pF (suppresses false triggering), C2 – 33.0 µF x 50 volts, C3 – 470 µF x 50 V.
  • Transistor VT1 – KP 501A.
  • Relay K1 can be used of any type whose operating current does not exceed 150.0 mA.

The circuit is powered from a source with a voltage of 12…24 V.

Now let's look at an option based on the NE555 asynchronous RS trigger. The device diagram is shown below.


Designations:

  • Resistors: R1 – 1.0 MOhm, R2 – 1.0 MOhm, R3 – 1.0 kOhm.
  • Capacitors: C1 and C2 – 15 nF, C3 – 10 nF, C4 – 0.1 µF, C5 – 100.0 µF x 25 V.
  • Diodes: D1-D2 – 1N4001, D3 – standard indicator LED.
  • Microcircuit - NE555,
  • The relay is the same as in the previous electrical circuit.

The above diagram does not need to be configured.

Concluding the topic of homemade sensor devices, we should mention the Ardunio system. On this platform, you can assemble a switching device that can be easily integrated into a Smart Home. In addition, such a device can be easily configured to operate independently, in accordance with a given program.


In addition, the system allows you to create several profiles for specific tasks. However, this will require programming skills. You can get more detailed information about the Ardunio platform on our website.

Note that in the above circuits, a power source with a voltage of 12-24 V is required to power the control circuit. For this purpose, it is best to use switching power supplies. As such, the electronic balance of LED and energy saving lamps. Detailed information on this topic can also be found on our website.

  • If the power supply uses a ground wire, it must be connected to the appropriate terminal.
  • If stranded wire is used for installation, its ends must be crimped or tinned. Otherwise, contact may be broken, which will lead to heating of the connection.
  • Do not use a touch switch with obvious signs of a violation of the integrity of the structure.
  • The load must match the parameters of the switch.
  • Quite often it is necessary to replace conventional switches for electrical appliances with new ones due to their rapid wear. They were replaced by more reliable touch switches (TS). The principle of their operation is as simple as possible. The devices can be made by hand. The photo below shows a switch with a sensor located on top and an indicator LED on the bottom.

    Appearance touch switch

    To turn on the light, a light touch on the sensitive element is enough. Touch switches are usually used to control lights, electric curtain rods and other low-power devices.

    Advantages of SV

    1. Convenient compared to a key switch, which does not always switch immediately. The devices are completely silent and there is no need to make an effort to turn them on.
    2. You can choose stylish models that will decorate your premises.
    3. Galvanic isolation of the circuit makes the device completely safe. The sensor can be touched with wet hands, the switch is sealed.
    4. No mechanisms that can break. The entire circuit consists of electronic elements.
    5. Possibility of combining with remote light control, as well as creating several switching channels in one device.
    6. Possibility of making it yourself.

    Operating principle

    Any touch switch is functionally divided into three parts:

    • a sensitive element (sensor) that responds to the touch or approach of fingers;
    • a semiconductor circuit that amplifies a weak electrical signal from the sensor;
    • a switch (relay or thyristor) that turns the load on and off.

    The figure shows a circuit of a touch switch with a supply voltage of up to 16 V. It is a simple semiconductor cascade amplifier. Used to switch on small loads. There is enough static electricity in the human body to open the first transistor of the cascade if you touch the bare conductor connected to the base with your finger.

    Circuit of a simple touch switch from a three-stage amplifier

    An LED is connected as a load at the output of the third stage, which serves to demonstrate the operation of the circuit. Instead, a relay is installed in the switch, for which a more powerful transistor can be selected. Copper foil can serve as a sensor.

    When you touch the sensor, the first stage opens, then the signal is amplified in the next two and the output becomes 6 V. It is enough to trigger the relay, which turns on the lamp with its contact (not shown in the diagram).

    Scheme

    The figure shows a diagram of a two-stage touch switch that you can make yourself.

    Switch circuit with two transistors

    When touching sensor E1, voltage from the human body is supplied to the amplifier through capacitor C1. Relay K1 is connected as a load, which is activated at the next touch, turning on or off its power contacts for powering the lamp. Diode VD1 is designed to protect transistor VT2 from voltage surges, and capacitor C2 smoothes out ripples.

    The relay is selected for an operating current of 15-20 mA (type RES55A or RES55B). The value of resistor R1 may need to be changed for the relay to work reliably. First, a 50 Ohm variable resistor is connected instead of it and adjusted until the relay from the sensor works. Then the resistance value is measured and a constant resistor with the appropriate value is found.

    The sensor used is foil-coated textolite, copper plate or metal with an anti-corrosion coating. It is easy to make it yourself. If the sensor is installed at a distance from the board, the supply wire should be shielded.

    The voltage source is a 9 V battery or a home-made mains power supply. A charger may be fine.

    It is better to assemble the switch circuit on a board, but you can also solder it with wires, since there are few parts. To connect them together, wires 2-3 cm long are used. To connect to the contact of the sensor and relay, the length of the wires will be no more than 10 cm.

    When soldering, it is important not to overheat the transistors and the 0.22 uF capacitor.

    Transformerless power supply from a 220 V AC network does not require a separate source. The triac device is quite sensitive and works reliably. In the diagram below there is no galvanic isolation from the lighting network, but the sensor is protected from high voltage by resistors R1 and R2 with a total resistance of 12 mOhm, as well as field-effect transistor VT1 with high resistance of the drain-source-gate junction. The sensitivity of the circuit is adjusted by changing resistance R2.

    In such circuits, when they are energized, touch is allowed only to the E1 sensor.

    Scheme of a touch electronic switch on a triac

    The trigger is built on an integrated circuit K561TM2 (DD1). From its output 1, the signal goes to the base of the transistor current amplifier VT2, the emitter of which is connected to the control terminal of the triac VS1. As soon as a voltage of 3 V appears on it, the triac opens and turns on the light source. The next time you touch the sensor, the trigger changes state and an opposite signal appears at output 1, turning off the EL1 lamp.

    The load power for this circuit is no more than 60 V. If it needs to be increased, the triac is installed on the radiator.

    There are circuits with a dimming function. When you briefly touch the sensor, the lamp will light up and go out. If you hold your hand on the sensing element, the brightness will increase and then decrease. A similar device is convenient to use for a table lamp at your desk. You can set a specific lighting level by removing your hand from the switch. The figure shows a diagram of the touch controller.

    Touch dimmer circuit

    The signal is supplied from the sensitive element to the K145AP2 microcircuit, and it controls the triac VS1 through the transistor VT1. Power is supplied from a 220 V network. The HL1 LED is a voltage indicator and illuminates the sensor in the dark.

    Technological progress does not stand still and over time affects all spheres of human life. Home improvement was no exception. For example, a touch-sensitive light switch, which appeared quite recently, has already managed to occupy a worthy niche in everyday use.

    The device not only increases the level of comfort, but also increases the service life of lighting fixtures, and is also a stylish design element.

    Let's take a look at the operating principles and design features of these devices together. What points should you pay attention to when choosing and how to properly install a touch switch.

    The appearance of the classic model of an electronic switching device is almost identical to touch panel and is a screen made of glossy electrochromic material (crystal glass) with markings applied to it. There is a wide variety of design options, colors and configurations of devices.

    Regardless external characteristics and the number of connected consumers, the sensor device consists of the following main parts:

    1. Controller or control unit. Behind the decorative front screen there is an active surface of the sensing element that responds to various stimuli. Based on the type of touch switch, the stimuli are: touching the object of influence, in some models approaching, clapping your hands, voice command.
    2. Semiconductor converter. IN previous block a signal is generated, which in this section is converted into an electrical signal of sufficient power to operate.
    3. Switching part. By means of the switch, the main actions in the electrical circuit are carried out: opening, closing or smoothly regulating the degree of load supplied to the lamp.

    Based on the design of the electronic product, its operating principle is obvious: by lightly touching the panel with your fingers, a signal is produced, which is converted and causes the relay to turn on.

    Additional functions built into the universal switch touch type, are often used for arranging a smart home system: monitoring the operation of heating devices, opening/closing window roller shutters and others

    Distinctive features of a touch device

    The electronic device belongs to the high-tech generation of devices, the main purpose of which is to control illumination. The principle of its operation is based on adjusting the current using a microcircuit, while conventional switches use standard type sliding contacts.

    This fee excludes education short circuit. This means that the service life of the lamps, as well as the life of the switch itself, is significantly increased.

    Household modifications of electronic switching devices are used in networks with a voltage of 220 V. They are used to connect sconces, control and adjust the backlight or main illumination

    Maximum convenience of controlling lighting devices is the main advantage of a touch (electronic) switch.

    It differs from the usual one by the presence of a special sensor, which served as the basis for the name of this type. A sensor located in the structure detects the radiated heat of the hands and responds to touch or to a sound signal.

    Sensory mechanisms can be found in Everyday life almost everywhere. This modern sensor allows you to monitor various activities

    Since the sensory sensing element itself is not capable of reproducing signals sufficient to start adjusting the lighting equipment directly, the device uses amplification devices. Such conductors are transistors or other alternative elements.

    To distribute amplifiers, a cascade placement method is used:

    1. The first place in the circuit, immediately after the sensor, is occupied by a transistor with high sensitivity and low power.
    2. Next in the oscillatory circuit is a similar mechanism, but with lower susceptibility, but with sufficient power to transfer a large load to the element.

    Quite often, electronic switches use galvanic isolation of the control circuit, where the control signal is sent through optical radiation - an optocoupler. Thus, the fragile part of the mechanism, namely the sensors, is separated from the power part.

    It is also possible to use the radio range, where commands are sent through the air protocols of the involved wireless network, for example, BlueTooth or Wi-Fi.

    The sensor has a current strength of only a few milliamps, which is insufficient even to transmit a signal to the base of the transistor. Therefore, amplifiers are used to send commands in the touch switch

    Nutrition active elements, included in the electronic switch, can be carried out using batteries or the mains. However, for the second option, it will be necessary to perform certain manipulations to rectify the mains voltage and then cut it to the required level.

    The simplest example is a semiconductor Zener diode. In rare cases, you can find a built-in full-fledged pulse block nutrition.

    Types of electronic switching products

    Despite the fact that touch switches are divided into six main types, only three are used in everyday life, namely: capacitive, optical and high-frequency. Let's look at them in more detail.

    Capacitive devices - extravagance or necessity?

    The capacitive type works as a light sensor and is capable of registering the presence of an object at a set distance. The device is mounted instead of standard light switches, but does not require pressing a button/key mechanism to operate.

    The essence of the work is based on the following algorithm of actions: when the hand approaches the sensitive area touch screen, mainly at 40-50 mm, the device executes a given command - it adjusts the lighting equipment, turning it on or off. Some options require a light touch to the active switch panel.

    The Chinese company Suntruth Electrical is one of the few market representatives specializing in the production of touch switches installed in place of conventional

    For some, such functionality will be perceived as overkill, but many consumers, especially their female counterparts, appreciate the essence of such a mechanism.

    For example, if in the process of cooking in the kitchen you need to turn on additional lighting, then a slight movement of your hand, no matter if it is wet or dirty, can easily control the electronic switch.

    The main representatives of capacitive electrical accessories for controlling lighting equipment are produced by the following companies: Jung, Berker, Livolo and Steinel. Despite their popularity, many developers abandoned this type of product and refocused production on separately installed types of devices.

    Comfort and savings of optical switches

    The switch, equipped with an infrared sensor, perceives exclusively thermal radiation in the infrared range emanating from the body during movement. His alternative name is a motion or presence sensor.

    Optical models with a pyrodetector are designed for infrared radiation with a wavelength of no more than 9 microns. Devices from the Delta reflex series from Siemens are universal. They can be installed both on the ceiling and on the wall and even outdoors

    The operation of this device is based on the operation of a sensitive pyroelectric element. The optical system redirects heat rays into a semiconductor receiver surrounded by a plastic storage lens.

    The last element is divided into segments. Due to this, the area in front of the IR sensor is divided into sequentially located sensitive and insensitive zones, and, accordingly, visible and blind sectors.

    The operating principle of the device is as follows: as soon as a moving thermal object enters the area controlled by the lens, a voltage pulse is generated in the pyrodetector. By means of an amplifier, this signal increases, and the switch turns on the lamps.

    The most convenient for home use are infrared switches with a sensitive, narrowly directed element placed on a hinge, with one, two or three free phases. Due to this, it is possible to adjust the required level of height and tilt of the lens view.

    Relatively recently, Siemens presented new series optical touch switches Delta Reflex. This universal devices, mounted in any area of ​​the room, including external ones, with a degree of protection from external adverse factors IP 55.

    High-tech models are equipped with a control panel, through which the programming of various functions is reproduced, for example, setting a shutdown delay timer or simulating presence for a given period.

    Convenience and practicality in high frequency devices

    High-frequency touch switches are represented by active type (light) and volume sensors. Structurally, these devices are quite similar to the previous version, but the response principle is significantly different.

    The operation of the detector is based on the use of photodiodes. The moment a light quanta hits the photosensitive area, the device turns off the lighting equipment. At the same time, its body has a special regulating mechanism, with the help of which the required level of illumination is set.

    Such intelligent mechanisms are mostly used for lighting facades. When dusk sets in, they turn on the lights in the area, and when it gets light, they turn them off.

    Despite the high degree of protection, light detectors may not work correctly when snow accumulates - having decided that it is dusk, the device turns off the lighting, so the snow must be constantly cleared

    TO popular models include sensors from German companies Steinel and Osram. Both products installed in place of an old light bulb and individual devices are presented.

    Installation is carried out in a break in the electrical circuit that supplies power to lighting devices. The device has high degree protection, no less than IP 44.

    The operating principle of the volume sensor is based on the emission of weak high-frequency pulses reflected from various pieces of furniture and decor, floors and walls.

    Having created a complete picture of the room in the field of reflected microwaves, the light control device inspects it at certain intervals. If a new object, a command is generated and the light turns on, if nothing changes, then the device remains in off mode.

    The main manufacturer of such devices is the same company Steinel. They are produced as switches installed instead of standard ones or, more expensive models, in the form of table lamps.

    Marking and connection details

    We will analyze the markings using the example of an electronic switch model VL C701R from Livolo. The modification of the device is indicated by the Latin letters C6, C7, etc. Next is a two-digit number indicating the number of connected lamp groups: 01, 02 and 03.

    Explanation of the VL C701R model markings: VL – abbreviated name of the manufacturer; C7 – series; 01 – one controlled line; R – radio remote control

    The last letters will indicate additional functionality of the touch switch:

    • R – radio control;
    • D – dimmer mechanism, allowing for smooth regulation of the degree of illumination;
    • S – pass-through switch function;
    • T – shutdown timer.

    The connection diagram for the touch switch is the same as for the dimmer.

    Conclusions and useful video on the topic

    If you decide to turn your home into an intelligent one, you should use tips for choosing electronic models. About this in the story:

    Having decided on the model and the necessary functions, it is important to figure out how to reproduce the connection:

    Despite the high price category, touch switching devices are equipped with such powerful functionality, which is quite enough to equip a smart home system. Having selected and purchased a suitable model that meets your needs, you can make the connection yourself.

    You have personal experience using touch switches for lights? Please share it with our website visitors. Tell us about the advantages and disadvantages of such devices that you noticed. Write comments in the block below the article.

    Externally, the touch light switch looks like a crystal panel with markings. Household models used in 220 volt networks may differ in color, shape, and surface texture. Recently, touch switches are increasingly used for:

    • Sconce connections
    • Controlling lighting elements for multi-level ceilings
    • Adjusting the main lighting in the apartment

    You can buy such a device or make it yourself.

    Devices different types may respond to:

    • Touching a finger to the work surface
    • Moving your hand closer to the sensor
    • Other changes in room conditions (temperature, movement, sound, time)

    The touch switch can be equipped with additional functions; its design is based on different principles actions. It is worth identifying 4 popular modifications:

    1. With remote control. Convenient to use for controlling sconces, LED strip, etc.
    2. Capacitive. Responsive to light touch. You can make such a device yourself; more on that below.
    3. With timer. Helps save on electricity by turning off the lights when there is no one in the apartment.
    4. Contactless. Reacts to certain features of the environment: sound, changes in light levels, temperature changes, movement.

    Each of the varieties is possible. With its help, the brightness of the lighting in the room is adjusted.

    Touch switch device

    Regardless of the principle of operation, touch switches have the same structure: they all consist of four main parts.

    1. Front surface. Sometimes a lighting element is installed behind it.
    2. Sensor. The principle of operation of the switch depends on its type.
    3. A switching circuit that converts the signal received by the sensor into an electrical one.
    4. Frame. It can be surface-mounted (installed externally) or internally mounted (built into the wall).

    Models with continuously adjustable lighting intensity

    If you need a device that allows you to change the brightness level gradually, you should pay attention to touch switches with dimmers.

    Some of these devices can be adjusted using a remote control. You can adjust the brightness of sconces or LED lighting without getting up from your chair.
    The touch switch with this device extends the life of incandescent lamps by eliminating the effect of sudden voltage supply.
    The connection diagrams for some devices require a power supply or dimmer. Such a switch device is ideally suited for circuit control LED strip.

    Models for mounting LED lighting

    Touch switches for LED strips and profiles are also called “dimmers”. They can also be used with other devices powered by 12 V.
    Dimmers allow you not only to turn on or off a section of LED strip, but also to adjust the brightness.
    Electronic devices most often come with touch controls. They are sometimes included in interior LED lighting schemes for:

    • Arrangement of entrances and staircases
    • Emphasizing the apartment design style
    • Equipment of the “Smart Home” system

    Many of them are not designed for 220 volts, so you need to connect separate devices for sconces and chandeliers.

    Capacitive sensor

    Capacitive light switches are more sensitive. The operating principle is based on the existence of an electrostatic field. It also fills the space around the sensor. When the capacity in this field changes (a person brings his hand to the switch), the sensor is triggered and turns on the sconce or chandelier.
    The sensor is based on a simple capacitor. The two electrodes on the surface of the switch are its plates. When a physical object approaches them, the capacitance of the capacitor changes. This becomes a signal to turn on the light.
    Each model has individual characteristics. The sensitivity of some of them can be adjusted during installation.

    How to connect the device

    There are no technical features for installing touch switches in a 220 volt network. .
    For example:

    • If the device supports the remote control control function, then it must be visible from the seating area
    • Models that respond to temperature changes should not be placed near a heating radiator

    The connection diagram for the switch for the LED strip may differ.
    It is important to remember the safety rules when working with electricity and turn off the meter. Necessary .
    If the device is overhead, you will not have to make a recess in the wall to install it. The process of connecting such a device is quite simple. .

    How to make a touch sensor

    Having experience with a soldering iron, and having obtained some parts, you can create with your own hands a simple touch switch, designed to operate on a 220-volt network. The most simple circuit looks like that:

    Capacitor C3 is not necessary.

    So, to create a touch switch with your own hands you will need the following parts:

    • Resistance at 30 ohms
    • Transistors KT315 (two)
    • Electrolytic capacitor (100 µF, 16 V)
    • Simple capacitor (0.22uF)
    • Semiconductor D226
    • Powerful battery or power supply (output voltage 9 V)

    All this needs to be soldered according to the diagram. In a case of a suitable size (you can use an old surface-mounted switch), a hole is made on the front part. The wire comes out into it. To operate the touch-sensitive light switch, the circuit must be connected to the power supply, and the wiring must be connected to a metal plate, which will be attached to the front plane of the homemade device.

    Most likely, creating an overhead touch switch with your own hands will cost less than buying a real one. The resulting device can be used to connect lighting in the house.

    DIY capacitive switch

    A do-it-yourself capacitive light switch can be used to create LED strip lighting or control chandelier lamps. It can also be surface-mounted or built into the wall. The scheme is not as simple as the previous one.

    The WA1 sensor reacts to the approach of the palm. The capacitance is introduced into the oscillatory circuit on transistor VT 1 and changes its frequency.

    Resistances R6 and R7 are needed for stable operation of the device during voltage surges from 4 to 10 volts.

    Using a touch switch, you can control not only various lighting fixtures, but also use them to control curtains or as doorbell. Exist Various types switches. Below is a list of switches and their connection diagrams.

    Important instructions for installing touch switches

    Installation of all touch switches is carried out without connecting to power and without a glass panel! The glass panel must be installed on a switch to which no power is connected (the machines are turned off). The glass panel can be removed using a flat screwdriver. To do this, insert a screwdriver into the hole and carefully turn it until it clicks.

    1. Unpack the switch.
    2. Connect the light switch.
    3. Screw the light switch flush into the mounting box.
    4. Secure the front panel; there should be a “click” sound.
    5. Turn on the power (automatic).
    6. The switch will work after the sensor self-adjusts for 1 minute.

    Setting up remote control of Livolo switches

    Switches that support remote control in the product article they have the letter R. To set up the remote control, you need to program the operation of the switch with the remote control.

    1. Press the sensor on the switch and hold it for about 5 seconds. until the beep sounds,
    2. Press a button on the remote control (eg button A).
    3. You will be informed about the completion of synchronization by a sound signal. Press A to turn on the light, press A again to turn off the light.
    4. Possible programming of buttons on the remote control: A, B and C – ON/OFF, D – turn everything off.
    5. For a dimmer, after synchronizing the remote control, the function of the button is as follows: A – ON, B – increase brightness, C – decrease brightness, D – OFF;

    To cancel synchronization, touch and hold the sensor for 10 seconds until you hear a double beep. If you release the sensor after the first sound signal or after the first backlight flicker, synchronization will not be canceled

    An example of the implementation of lighting in a bedroom using Livolo pass-through switches

    1. Implement control of the general lighting of the room from three places: at the entrance to the bedroom, next to the bed, to the right of the bed.
    2. Implement control of sconces on the left of the bed and on the right of the bed.

    Annotation. After connecting and synchronizing, the light control in the room will be like this:

    • Lamp No. 3 is controlled from switch No. 1, No. 2, No. 3;
    • Lamp No. 1 is controlled from switch No. 1
    • Lamp No. 2 is controlled from switch No. 2

    Video guide on how to control lighting brightness using a Livolo touch dimmer:

    Control of a touch light switch with a dimmer (dimmer):

    1. Briefly touch the switch sensor to turn the light on/off.

    2. While holding your finger on the sensor, adjust the brightness of the lamp.

    3. When turned on again, the dimmer ensures the brightness of the lamp installed before turning off.

    Note:

    1. Only suitable for dimmable LED lamps, incandescent lamps or dimmable floodlights.

    2. The switch is not suitable for fluorescent lamps.

    3. Load power must be at least 25 W, no more than 500 W. The switch may become slightly warm.

    LED adapter

    In some cases, for the correct operation of the touch light switch with LED lamps It is necessary to install an LED adapter to prevent the lamps from flickering when turned off.

    LED adapter connection diagram. The adapter is connected in parallel to the load.

    LED adapter connection diagram when using LED strip. The adapter is connected in parallel to the transformer into a 220 volt network.

    If there is a zero in the installation box where the switch is installed, then the adapter can be installed near the switch. The scheme will be like this.

    The switch has an intelligent processor. Electronics controls the entire load management process. In the event of a circuit break, the touch switch with its advanced control circuit is simply switched off, so we have additional autonomous system security. Depending on the position of the rotor, the load created by the hood is variable. In some cases, the load approaches zero, which causes the circuit breaker to trip. You can train the switch to work correctly with the hood using an adapter. Connection diagram for the hood adapter:

    Starting current stabilizer

    Using the Starting Current Stabilizer, the touch switch will work correctly with motors, such as hoods, or powerful transformers for 12-volt LED strips, LED lamps with drivers, which, when turned on, consume a current tens of times higher than the rated current - 5A.
