In the domestic electrical market, there are many types and styles of switch sockets with lighted tact switches, and their colors and shapes are gradually personalized. From the initial household pull switch, second-generation acupressure switch, third-generation large rocker switch, to the current steel frame switch, this development process of the switch fully demonstrates the improvement of the home environment and the diversity of consumer needs. Then, let's take a look at the classification and development prospects of lighted tact switches.
The survey shows that light touch switches with light are favored by consumers because of their performance and advantages, and gradually occupy the mainstream position in the light touch switch market.
The classification method of lighted tact switches can be divided into three types: reflection type, transmission type and mirror reflection type according to the detection method. The transmission type has a long detection distance and can detect the density (transmittance) of translucent objects. The reflective working distance is limited near the beam intersection to avoid background influences. The specular reflection type has a long reflection distance, which is suitable for long-distance detection, and can also detect transparent or translucent objects.
According to the structure, the tact switch with light can be divided into three types: separate amplifier type, built-in amplifier type, and built-in power supply type.
1. Amplifier separation The tact switch with light separates the amplifier from the sensor, and is made of ASIC and mixed-load technology. The sensor has the characteristics of ultra-small and various varieties, so the function of the amplifier is many. Therefore, this type adopts the terminal block connection method, which is a universal AC and DC power supply. It has the function of on and off delay, and can be set to light the sound and move the switch, control 6 kinds of output states, and have two output modes of contact and level.
2. The built-in amplifier type combines the amplifier and the sensor, adopts the special integrated circuit and surface mount technology, and uses the DC power supply to work. Its response speed (0.1ms and 1ms two kinds) can detect narrow and high-speed moving objects. After changing the polarity of the power supply, the brightness and darkness will be switched, and the self-diagnostic stable work area indicator can be set. It has both voltage and current output modes, which can prevent mutual interference and facilitate system installation.
3. The built-in tact switch of the power supply with the light tact switch combines the amplifier, the sensor and the power supply device, and is made of the special integrated circuit and the surface mount technology. Generally, AC power is used, which is suitable for replacing the contact type travel switch in the production site, and can be directly used in the strong current control circuit. Self-installation and self-diagnosis stable working area indicator light, output is equipped with SSR solid state relay or relay normally open and normally closed contact to prevent mutual interference, and can also be installed close to the system.
