ABSTRACT:
A sensor device is provided for generating an electrical output signal in dependence on the position of a light source in relation to the sensor device. The sensor device has a three-dimensional switch carrier with several adjacent faces oriented in different directions, on which faces at least two sensors are arranged. On the two sides of a central face, there is arranged in each case a face, with an infrared light (IR) photodetector in each case, oriented at an angle to the central face, whereby the faces on which the IR photodetectors are arranged are not directly adjacent to one another.
