Abstract
A capacitive proximity and/or contact switch includes a cover plate having an upper side and an underside. The upper side provides a sensitive area of the switch and the cover plate, at least in the region of the sensitive area, is at least partially non-conductive. A conductive sensor face is disposed at a distance from the underside of the cover plate. The dielectric system of this capacitive proximity and/or contact switch is formed of the cover plate, at least one non-conductive element facing towards the sensor face and at least one conductive element between the cover plate and the non-conductive element.
