What is a capacitive sensor touch switch?

According to the switch principle, touch switches are divided into resistive touch switches and capacitive touch switches. Among various technologies, capacitive touch sensing technology has become the mainstream of touch sensing technology.

The extensive application of membrane switch panel keys in instruments

In electronic circuits, key switches without locks are widely used. Because it does not need to pass a large current.

How to check the quality of membrane switch
