Abstract
Electrical circuit for swingable headlights of a motor vehicle including an electric motor for positioning the headlights and a multi-step switch for initiating the movements of the motor for positioning the headlights. The circuit also includes a contact-disk device coupled to the electric motor for controlling the end positions of the headlights, and first and second relays connected to the multi-step switch. The multi-step switch is provided with at least two step positions whereby the second relay is energized in dependence upon at least one of the step positions of the multi-step switch and by a voltage drop, the motor being driven in response to the energization of the second relay.
