ABSTRACT:
A capacitive and/or touch-sensitive switch has an electroconductive body which is disposed between an electrically insulating covering plate and a carrier plate disposed at a distance from the covering plate, and can be elastically deformed in the spacing direction. The electroconductive body is applied to the lower side of the covering plate with the upper end thereof, defining a sensor surface, and to an electroconductive contact of the carrier plate with the lower end thereof. The electroconductive body is a pressure spring wound out of an elongated body.
