Product Description

What is capacitive touch switch?

Capacitive touch switch combined normal panel and capacitive sensor together.Unlike traditional push-button switches, capacitiveswitches don’t need press,.Only put finger on the button in the sensing area, can be recognized by the machine through the filmsensor operation.Most of the buttons are made by acrylic panels or injection parts with backlight display function which has agood appearance .Capacitive keypad has a fashionable appearance and long service life, so it has great advantages in many applications such as smart home appliances, cars, mobile phone communication, medical instruments and toys.
