Abstract
A sensor element for a touch switch device has a sensor element body of elastic, electrically conductive material. The sensor element body has two parallel end wall areas as the top and bottom surfaces, which are integrally connected in one piece by inwardly cambered side wall areas. Such a sensor element body can be very easily compressed. The wall thickness of the wall areas is substantially the same throughout. Such sensor elements can be constructed by forming a linear strip of such material having a cross section as described, where the strip is cut into individual pieces, thereby forming each individual sensor element.
