Abstract
A mechanically actuable electrical control relay has normally open contacts at least one of which is associated with a movable armature. A fixed, magnetizable core part has a winding or coil associated therewith. A movable core part associated with the armature is connected to a mechanical actuator for moving the movable core part toward the fixed core part. With the winding or coil energized, the fixed core part is magnetized and the movement of the movable core part (which is of a ferrous material) into proximity to the fixed part completes a magnetic circuit therebetween and the contacts are closed to establish and maintain an electrical circuit controlled by the relay. Improved circuitry for operating automotive equipment in which the control relay is one of the components is also described.
