The switch (22) has a printed circuit board (20) disposed at a distance below an underside (14) of a touch panel (10) e.g. plastic plate. A capacitive sensor element is disposed between the underside and the board (20). The sensor element is in electrically conductive contact with the printed circuit board, and has a compression spring and a contact element (28) formed of an electrically conductive material. The compression spring has a side facing the touch panel, and the contact element is disposed on the side of the spring and is in electrically conductive contact with the spring. |
