Abstract:
A touch-sensitive momentary-contact switch has an optical sensor, particularly an infrared sensor, and an evaluation circuit. The evaluation circuit is able to identify a malfunction in the optical sensor, so that the momentary-contact switch can be switched off, for example, for safety reasons. Therefore, it is possible to identify a malfunction in the optical sensor.
