The development history of smart switches

smart switches are also called smart wall switches. They are used in electronic wall switches.Based on the evolution of the original rocker-type mechanical switch Life, since Edison invented the light bulb in 1879, there has been a simple machine Mechanical switches, more than one hundred years have passed, and contemporary wall switches have not been fundamentally changed. Change, without any breakthrough development, still use mechanical switch mode, It was not until 1992 that electronic technology began to enter the field of wall switches. Only used for voice-activated delay switches in public corridors, touch delay on shut.

By the year 2000, the wide application of human body pyro-sensor, time-delay switch With significant development, the human body induction switch gradually replaces the voice-activated delay switch And touch the delay switch, at the same time the dimming adjustment of the thyristor phase control Speed switch is also conceived, knob-type dimmer switch, mainly suitable for incandescent Light, knob-type speed control switch, mainly suitable for fan motors.

The above Although this kind of switch has entered the electronic mode from the traditional mechanical mode, its The function is relatively simple, and it is only used in specific occasions. Mechanical switches cannot form an impact and replace, in addition, due to the existing wall switches Most of the wiring patterns are only single live wire access mode, and the neutral wire is directly connected. Lead to the load, in the switch, there is only the live wire and no neutral wire, which cannot form a return Power supply, which restricts the introduction of many electronic technologies and Application, the development of electronic technology in wall switches for more than ten years has been in the initial stage 

The simple function stage is hovering, there are always only five types: touch delay on Off, voice-activated delay switch, human body induction delay switch (PIR), knob Dimmer switch, knob speed switch.

In recent years, with the development of science and technology, a major breakthrough has been made in the power supply technology of the wall switch with single live wire access. At the same time, the microcomputer processing chip is introduced into the electronic wall switch, making the electronic wall switch with various functions become practical. Feasible, with this technology, a series of new electronic wall switches have been launched. At this time, the types of electronic wall switches have been greatly enriched and developed. Therefore, it is necessary to classify them.

Electronic wall switches are classified according to their functions as follows: 1) human body induction switch, 2) electronic dimmer switch, 3) electronic speed switch, 4) electronic time switch, 5) other smart switches,

The above type of electronic wall switch is mainly used in conjunction with the most commonly used lights and fans in the home.

However, the home life has undergone major changes in the past two decades. Many household appliances have entered the family, which has greatly enriched people’s lives, such as refrigerators, air conditioners, LED lights, decorative ceiling fans, exhaust fans, and bathroom heaters. It is still a simple mechanical switch, and all it can do is simply turn it on and off. It cannot operate according to the characteristics of different electrical appliances.

For example, the exhaust fan is installed in the bathroom. When a person leaves, it needs to be turned off after a period of time to eliminate it. Strange smell, some public places require people to automatically open it, and after people leave, it will be closed after a period of delay. Ceiling fans installed in the living room not only need to switch, but also need 3 or 5 speed adjustment, installed in the bedroom requirements There is a timing function, but it is different from the delayed off function of the exhaust fan. It is best to be equipped with a remote control, fingertips lightly move, and the style is free to control; but for the LED light, it is more important to switch the function at the same time. It also needs dimming/coloring functions, and so on.

For different household appliances, more intelligent switches are needed to match them. This will inevitably lead to a complete revolution of wall switches in a century.

So far, the comprehensive definition and classification of smart switches have begun to take shape. Smart switches are the abbreviation or general term for electronic wall switches and smart switches for household appliances. Smart switches are wall switches with microcomputer chip control, multiple functions, and multiple purposes. It evolved from the wall switch, and expanded a variety of home appliance switch series,

With the emergence of new household appliances in the future, there will be more new household appliances switches; it is not only suitable for ordinary lighting fixtures, but also suitable for different household appliances. It is a humanized and intelligent switch.

With the emergence of new household appliances in the future, there will be more new household appliances switches; it is not only suitable for ordinary lighting fixtures, but also suitable for different household appliances. It is a humanized and intelligent switch. The smart wall switch supports mobile APP control, while also realizing smart voice control, setting different usage scenarios, timing switches, smart sharing, etc. Smart switches have become an indispensable part of the smart home system
