Wiper Switch (SWS)

Wiper Switch (SWS)




The wiper switch is essentially an incremental switch, it does not lock into any positions. A "roll" mode is integrated in the operating concept. This allows one-touch control of wiper speed.

Roll mode:

1 tap up=stage 1
2 taps up=stage 2

from stage 2:

1 tap down=stage 1
2 taps down=off
3 taps down=single wipe

Pushing the wiper switch upwards past the detent activates stage 2

A push button (1) used to turn the Rain/Light Sensor system on and off is on the end of the wiper switch. A four position thumb wheel (2) controls the sensitivity. The function status is indicated by LED (3).

A wash cycle is requested by pulling the stalk towards the driver

The driver requests for the functions of the wiper system are signalled using Hall sensors inside the wiper switch. The sensor signals are interpreted by the Steering Column Switch Center (SZL).
