Abstract
A capacitive touch switch includes a sensor button which is disposed between a circuit board and a cover plate and which forms a terminal of a capacitor that is variable in its capacitance by an approach. The sensor button includes a body of a flexible material, which body can be adapted to the cover plate and is embraced by a conductive net.
Claims17
A capacitive touch switch, comprising:
- a circuit board;
- a cover plate;
- and
- a sensor button disposed between said circuit board and said cover plate and forming a terminal of a capacitor being variable in capacitance upon a user approaching said cover plate, said sensor button having an electrically conductive layer and a body, said body being formed of a flexible material and said body being adapted to said cover plate, said body being electrically non-conductive and at least partially enclosed by said electrically conductive layer.
