Touch switches

Touch

— the sensor is an electromagnetic sensor that responds to touch with a fingertip. It is enough to lightly press the working surface of the touch sensor, as the electrical circuit closes / opens. The main advantage of the sensor is the absence of rubbing pairs that are subject to mechanical wear. Also, touch-sensitive electrical accessories do not emit a click characteristic of keys and buttons. Usually, touch switches are more expensive than mechanical counterparts using buttons / keys.
