Zusammenfassung: | An input device for an electrical device includes a base which can be attached to the electrical device and has at least one light source for producing a measurement beam, and at least one sensor for detecting the reflected measurement beam. An input actuator is movable in relation to the base and includes a plurality of reflection bodies for deflecting the measurement beam onto the sensor. Each reflection body has an entry area for entry of the measurement beam into the reflection body, at least one reflection surface for reflecting the measurement beam, and an outlet area for outlet of the measurement beam from the reflection body. |
