High/low beam headlamps and fog lamps switch assembly

Abstract

A switch assembly having a sliding actuator adapted to be moved by a cam on a stalk lever. Initial movement of the actuator from a neutral position by user movement of the lever moves a first contact carried by the actuator to break a connection between a power bus and a fog lamp terminal strip in a planar array of strips. Further movement causes a second contact carried by the actuator to make a connection between another power bus strip and a high beam terminal strip. Continued movement of the sliding actuator causes rotational movement of a bi-stable rotor latched in one of its two bi-stable positions. Movement of the rotor causes a third contact on the rotor to shunt the second contact to make a second connection on another high beam strip and a fourth contact on the rotor breaks a second connection on the strip for the fog lamp electrically in series with the first connection. Subsequent return of the sliding actuator to its beginning or neutral position by user release of the lever does not effect the position of the third and fourth contacts, as the rotor is latched. A subsequent actuation of the stalk lever by the user again moves the sliding actuator to effect movement of the bi-stable member in the opposite direction to disconnect the high beam headlamps and reconnect the low beam and fog lamps, and the bi-stable member is again latched in the position with the low beams headlamps on.
