LED and light-conducting element

The LED - in conjunction with the light-conducting element - has the task of projecting light from above onto the code disc. The LED is directly soldered onto the sensor circuit board. The light-conducting element is clipped onto the board of the steering column switch cluster.

The light-conducting element is split three ways at the light exit. The light is projected in such a way that a light field is formed at each light exit and beamed downwards onto the code disc. Depending on the pattern on the code disc, light is allowed through or not.
