1, SGL8022W touch chip can achieve LED light touch switch control and brightness adjustment. (Same series of SGL8022K and SGL8022S are capacitive touch chips with two touch channels and two logic control outputs). It has the following functional characteristics and advantages: The brightness of the light can be adjusted as needed, the selection range is wide, and the operation is simple and convenient.
Mirror touch switch adopts the principle of touch sensor chip, abandoning the traditional mechanical button switch, the perfect combination of modern technology and traditional switch, not only meets the aesthetic needs of modern peopleIt also greatly improves the safety performance. Intelligent design Mirror touch switch intelligent, easy to operate, excellent decorative effect. The text prompts on the touch screen make it easy for users to get started even without guidance.
Mirror touch switch intelligent and easy to operate, with a strong decorative effect. The mirror gives a clean, glowing feeling. Touch switches do not have the metal contacts of traditional mechanical switches, nor do they have circuit arrangements, and reduce the use of copper alloy materials in the manufacturing process. The overall structure is less used, safer and more environmentally friendly. Modern technology has greatly improved touch screens. As one's fingers touchWhen touched, the switch will respond.
Yes. Mirror touch switch is a smart mirror touch sensor switch specially designed for all kinds of bathroom smart light mirror, bathroom anti-fog light mirror, LED light mirror (mirror cabinet) and other products. This product has beautiful appearance, reliable performance, easy installation, thin size, sensitive touch and other characteristics. Suitable for all kinds of mirror lamps or other glass, plastic, ceramic or artificial stone surface touch sensing control.
Safe and reliable, generally toughened glass waterproof panel, wet hand is also operable. No arc is generated when opening and closing, and it is safer to use. Beautiful fashion: crystal tempered glassGlass panel, crystal clear. Smart: The switch can be controlled wirelessly. Wide application, low energy consumption: applicable to all kinds of lamps on the market, static standby power consumption is less than 0.011w, less than 1 KWH in 10 years.
Compared with ordinary mirrors, the bathroom smart magic mirror in addition to having mirror touch, beauty lighting, intelligent fog clearance these basic functions, but also voice interaction, check the weather and road conditions schedule and other life confidence services, such as during the wash, you just through voice or touch interaction, you can watch the news on the mirror, check the weather, or play music videos. And even control all kinds of equipment and lighting in the house.
Difference between touch switch and voice switch ic Touch delay switch When used, as long as you touch the electrode with your finger, the light will be lit, and the delay will be automatically extinguished after about 1 minute. It can directly replace the ordinary switch, without changing the indoor wiring. The right side of the dotted line of the touch delay switch circuit is the general lighting circuit, and the left part is the electronic switch part. VD1 ~ VDVS constitutes the main circuit of the switch, and IC constitutes the switch control circuit.
Touch delay switch circuit dotted right side is the general lighting circuit, the left part is the electronic switch part. VD1~VDVS is the main circuit of the switch, and IC is the control circuit of the switch. Usually, VS is in the off state and the light is not on. VD1~VD4 output 220V pulsating DC by R5 current limit, VD5 voltage regulation, C2 filter output about 12V DC for IC use. At this time, the LED lights up, indicating the switch position, easy to find the switch at night.
Working principle: The internal installation of the electronic touch IC and the lamp at the touch of the electrode to form a control loop. Touch switch is a kind of intelligent control switch, when the human body touches the sensing electrode, the touch signal is generated by a pulse of direct currentThe impulse signal is transmitted to the touch sensing terminal, and then the touch sensing terminal will send a trigger pulse signal, which can control the light.

Principle of touch switch Switch touch chip : When people touch the capacitive screen switch touch chip , because the human electric field switch touches the chip , the user's finger and the working surface form a coupling capacitor, because the working surface is connected with a high frequency signal, so the finger absorbs a small current, which flows from the electrodes on the four corners of the screen. In theory, the current flowing through the four electrodes is proportional to the distance from the finger to the four corners, and the controller obtains the position through the precise calculation of the proportion of the four currents.
When the touch sensing switch works, because the single-fire intelligent switch is powered by the pressure difference at both ends when the switch is turned off, when the switch is closedTherefore, the technical problem of touch sensing switch has always existed, which is the main technical bottleneck limiting the development of single fireline touch switch at home and abroad so far.
Table lamp touch switch principle Table lamp touch switch principle is the use of capacitor principle, when the finger touches the touch switch, it will form a capacitor, which will change the capacitor in the circuit, thus changing the current of the circuit, so as to control the switch of the table lamp.
Mathematical Answer group for you to solve hope to help you. This is the "electromagnetic induction switch", when the lamp is turned off, the two sides of the switch produce the same electric charge, forming the same electromagnetic field andElectrodes, so mutually repel switch touch chip ; When a person or a person uses a conductor to touch the switch, the switch part in contact with the person can be passed into the opposite charge and the opposite electromagnetic field and electrode of the other part of the switch, because the opposite attracts, so the two parts of the switch are combined, the lamp is bright switch touch chip .
