Detecting the Switching Signals of the Steering-column Switches: Notes
The switching signals of the F01/F02 steering-column switches are triggered by the steering column stalks. The relevant switches are located on the printed-circuit board of the steering column switch cluster. The steering column stalks do not have detent notches. Therefore, each time the steering column stalks are operated, they return automatically to their starting position.
The resistance to movement of the steering column stalks is increased at the end stops and in the individual switching positions. This provides the customer with noticeable feedback on the respective lever position.
The toggle switch is designed as locking. Three stop positions are available.
