Due to the flexibility of the circuit board, the force that occurs when the at least one control element is actuated is transmitted to the light-guiding body, so that the light-guiding body enables an additional function to be taken up. The at least one control element can still be illuminated via the opening in the circuit board. Using the switching dome provides a particularly simple way of making contact when the at least one control element is actuated. Due to the flexibility of the circuit board, it can also be easily adapted to the contour of the light guide body.
