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.
