Switching lights on and off by cotton: self-installation of the device

Are you sick and weary of searching your home for light switches all the time? Just like you could pull the cord on a lamp, picture how convenient it would be to be able to control your lights with a simple tug of a string. Now that technology has advanced and creativity has been added, this dream can come true. In this piece, we delve into the intriguing idea of turning lights on and off with cotton—a material that can be found in most homes.

Traditionally, light switches have been mechanical devices mounted on walls or fixtures, requiring physical contact to toggle the lights on or off. While effective, these switches can sometimes be inconveniently located or difficult to operate, especially for individuals with mobility issues. Enter the innovative idea of using cotton strings to control your lights. This DIY solution offers a simple and accessible alternative, bringing convenience and ease of use to any home.

The idea of using cotton to switch lights is both clever and surprisingly simple. A simple pull or release of the cotton string will allow you to remotely adjust the position of your light switch by fastening it to a pulley system. With this technique, you can easily convert your standard light switch into a mechanism that feels more tactile and more ancient.

This DIY project’s accessibility is one of its best features. The cotton switch is simple to install with common household items and doesn’t require much technical knowledge, in contrast to sophisticated smart home systems that need extensive setup and programming. Either a novice homeowner or an experienced do-it-yourselfer can quickly and easily install and customize this device to meet your needs.

Beyond just being readily available, cotton’s use as the main material for this project has other advantages. Cotton is perfect for making dependable and smooth pulling mechanisms because it is soft, flexible, and long-lasting. Because of its inherent qualities, it is also safe to handle and environmentally friendly, fitting in with contemporary sustainability practices.

Application of cotton switch

The purpose of the acoustic (or cotton) switch is to remotely control the electricity in different rooms—that is, without physically touching the toggle switch. The mechanism for this fixture is a hand clap. If there is sufficient power available, an acoustic controller can also turn on lighting sources, contactor coils, current converters, climate control systems, and other electrical and electronic equipment.

Acoustic switches in living rooms

The quietest rooms in the house, such as bedrooms, study areas, storage spaces, cellars, and libraries, are the ideal places for acoustic switches. If you install a device like this in your bedroom, you can read your favorite book for the night and curl up under the covers without having to get out of bed to turn out the light. All it takes to create a warm, engulfing darkness in a room is a simple hand clap.

By installing a cotton switch in the bedroom, you can turn off the lights without getting out of bed.

Installing such devices in noisy areas is not advised because background noise will frequently cause the device to be activated without authorization. As a result, the sound switch is inappropriate for use in living rooms, dining rooms, offices, and kitchens.

Wheelchair users will find the cotton switch to be very helpful, and kids will also benefit from it. Electrical devices are usually placed in children’s rooms at a height of 1.7 meters for safety reasons. The child must stand on a stool in order to independently turn on or off the light, which is dangerous because the infant could lose their balance and fall. The child won’t approach you repeatedly to turn on or off the light if you install a cotton switch. All he has to do is clap his hands to turn on or off the light.

Lighting of the interfloor space

With the help of a switch that reacts to the clap, you can control the light on the platform between the floors. For this purpose, it must be equipped with a photocoupler. The susceptibility of the motion sensor is controlled by a voltage divider with a resistor creating a photodiode. If the use of motion sensor is not essential, it can be disabled. To do this, set the resistor to the lowest value.

The light on the landing between floors is controlled by a clap-responsive switch.

When lighting the interfloor space, you can use the K176LA7 microcircuit. When it is applied, the electricity activation automatism does not rattle on the upper and lower indicators. With the electret microphone, an acoustic wave is received and transformed into an electrical impulse. Then, through the use of three-electrode transistors, the impulse is received by the logic sections of the microchip, which produce a signal lasting up to 10 seconds. During these 10 seconds, the lamp is in the activated state, i.e. in the activated state. е. in the on state. To disable it for daylight hours, you need to signal from the output of the element.

How the acoustic switch works

The clapper device operates in this straightforward manner: the load is turned on by the first clap and turned off by the second. The acoustic wave is picked up by a fairly sensitive microphone, which then sends the signal to an audio frequency power amplifier. After the strong signal reaches the key’s base, the transistor can be turned on thanks to its magnitude. The transistor’s electron-hole junction opens and conducts electricity when the key base receives an impulse. This allows the connected lighting device or relay to be powered on and controls loads.

Cotton switch and acoustic (sound) are not quite the same. The cotton sensor only activates when hands are clapped; the acoustic (sound) sensor activates in response to all sounds and noises. As a result, the cotton switch can be classified as an acoustic (or sound) switch.

Technical characteristics of the device operating on clapping

Light switches that are triggered by clapping sounds can be made yourself or purchased. Take the "Ekosvet-X-200-L" gadget, which is made by "Nootekhnika," a Belarusian company. It possesses the subsequent technical attributes:

• load power – up to 300 watts;
• Sound strength – 30-150 decibels;
• mains voltage – 220 volts.

The "Ecosvet-X-300-L" cotton switches are made to produce a loud, ringing sound when they turn on or off lights.

The kit comes with the switch itself as well as a box and installation guidelines. When compared to other manufacturers’ comparable devices, this switch’s price is fairly reasonable. The switch is made with an IP-30 protective housing. It can function in the range of -20 to +40 degrees Celsius. Almost any type of lighting fixture, including halogen, fluorescent, energy-saving, LED, and conventional incandescent lamps, can be used with such a device. The gadget is small enough to fit at the base of any light source—it’saboutthe size of a matchbox. Self-tapping screws or double-sided construction tape are used to secure the switch.

Components of the sound switch

The acoustic switch is easy to install. This is an illustration of a microphone amplifier using domestic KT315 transistors. In the final stage, a KT818 bipolar transistor’s high-power transistor key is utilized. A relay must be included in the circuit if lamps with power supplies greater than 12 volts are to be controlled. The relay can be crossed out if the anticipated loads are less than this amount. Wago 222 terminals are used to connect copper wires; these terminals have advantages and disadvantages.

Principle of operation of the dimmer acoustic switch

Electricity is switched on a dimmer using an opto-acoustic switch. It functions as follows:

1. The sound signal (in our case it is a clap) goes to the sensitive membrane of the microphone. There the sound is converted into an electrical impulse. When passing through the operational amplifier, the power of the pulse increases and the capacitor is charged. When the charge reaches a higher value than on the capacitance, the comparator is switched over. The zero at the output is replaced by a pulse from the logic section.
2. This circuit is sequentially activated in the switch after receiving an acoustic signal from the microphone. Then the transistor generator that directs the electrical impulses is started and the triac opens. This is used to supply power to the light source.
3. After some time, the capacitor loses its voltage level. In this case, the triac accepts the controlling electrical signals with a constantly increasing phase deceleration, as a result of which the light is switched off smoothly. With optimal selection of ratings, the light source is turned off with a pause of up to three minutes.

For an electrical dimmer switch, an optical-acoustic switch is utilized.
