Capacitive touch control switch can actually delete the effective touch of finger through more than 20mm thick insulating material shell,such as tempered glass or plastic film. It ensures product’s sensitivity, stability, reliability be not changed with ambient conditions and long-term use, and has the waterproof and anti interference ability.
Capacitive touch control switch don’t need user to touch metal directly, can eliminate potential safety hazard. The part of touch circuit is placed on the back of insulating material shell, it is easy to make a keypad sealed with the surroundings. It has no any mechanical components, don’t wear out, has unlimited life, can reduce the later maintenance costs.
