Electronic control for windscreen wiper - has impulse control with Darlington transistor as switch providing intermittent operation

The electronic control for the windscreen wiper circuit has an impulse control which is triggered by the parking switch. The potential between the trigger voltage and the time control capacitor is derived from the blocking potential for the control circuit. The system uses a Darlington transistor as...

Zusammenfassung:	The electronic control for the windscreen wiper circuit has an impulse control which is triggered by the parking switch. The potential between the trigger voltage and the time control capacitor is derived from the blocking potential for the control circuit. The system uses a Darlington transistor as the switching control for the intermittent operation, wit a reversing control for the park setting between wipes.
