Abstract
A capacitive touch switch, for a control panel of a domestic electrical appliance, includes a touch panel having an upper side and an underside. A printed circuit board is disposed at a distance below the underside of the touch panel. A sensor element is disposed between the underside of the touch panel and the printed circuit board and is in electrically conductive contact with the printed circuit board. The capacitive sensor element has a compression spring formed of an electrically conductive material and a contact element formed of an electrically conductive material, which is disposed on that side of the compression spring which faces the touch panel and which is in electrically conductive contact with the compression spring.
