The switch has a covering plate (10) defining a contact field (12) on a side turned towards a user. A support plate (16) is located on a side of the covering plate turned away from the user and arranged at a distance to the covering plate. A coupling element (18) is arranged between the covering and support plates corresponding to the contact field and stays in contact with an electrical conductive contacting area (162) on the support plate. A light source (20) is provided for coupling light beams into an electrical conductive and transparent plastic body (181) of the coupling element. |
