Washer/wiper control for car headlamps - has transistorised delayed switching circuit with bypass connection to washer switch

摘要

The transistorised control for the washer/wiper circuits has an RC timing control which not only switches on the headlamp wipers for a set time interval after the windscreen wipers have stopped, but ensures that the wipers operate for a set time interval after the washer pump is operated. The washer switch operates a bypass link directly to the output transistor of the control so that the wipers are switched on as soon as the washer is operated. This provides a simple control system for the windscreen and headlamp wipers.
