Bosch 0336920004 wiper pulse generator

One (1x) Bosch # 0336920004 wiper pulse generator switch in used condition. The rotary switch case side was sprayed a bit (see first pic) on one side. The switch is for 6/12V and not tested. I turned the switch and it makes the “click” sound. The rear is stamped with “Bosch 0 336 920 004 / made in Germany / Impulsgeber / 6/12V”. The knob diameter is 3 cm and the black rear is about 5 x 5 x 3 cm. Both are in same condition and you will get one (1x) if you buy one.
