What is a touch sensor button switch?
The touch switch is an emerging product with the development and progress of science and technology. He generally refers to a wall switch designed using the principle of a touch-sensitive chip, which is a replacement product for the traditional mechanical key-type wall switch. The touch switch that can achieve more intelligence and more convenient operation has incomparable advantages over traditional switches and is a very popular decorative switch for household products.
The principle of touch switch.
A touch switch is an electronic switch that can be turned on by lightly pressing the switch button when in use. When the hand is released, the switch is disconnected, and the internal structure is disconnected by the spring force of the metal shrapnel.
When the voltage is normal, the electromagnetic attraction is sucked into the armature, and the main contact can be closed. When the voltage drops severely or loses power, the armature of the Panasonic air switch is released and the main contacts are disconnected. When the power supply voltage returns to normal, it must be closed again before working to realize loss of voltage protection. The protection of people is also very good.
Advantages of touch switches.
The advantage of the touch switch is that it is suitable for high-density surface installation, some can be cleaned after welding, the seal can be dust-proof, it is most suitable for harsh environments, and the circuit design is simple. Product lifetimes range from 100,000 to 10 million. The product has become a series. But the touch switch also has its disadvantages. Frequent pressing will cause the metal shrapnel to lose its elasticity due to fatigue and failure. The touch switch cannot produce functions independently and must be used in conjunction with the PCB circuit board to form a complete opening access control system.
The package type of the touch switch.
There are three kinds of packaging for the touch switch: manual plug-in in bulk, SMT chip packaging, and DIP plug-in tape packaging.
The pin connection method of the touch switch.
Regarding the pin connection method of the five-pin touch switch: two pins form a group, the four pins are welded more firmly, and the fifth pin is used for the ground wire.
