Abstract
A multi-stage latching device for a carburetor which controls the idle speed by defining various throttle plate positions according to deceleration sensor switch, air conditioning switch and ignition switch states. The mechanism which moves the throttle plate consists of a primary force coil which energizes an armature against spring return and the position of the armature coupled through a shaft establishes the idle speed. The throttle position is determined by any one of three adjustably disposed latch coils which when energized, magnetically couple to a casing to define a stop. A circuit control associated with each latch deenergizes the primary force coil while maintaining the magnetic coupling of the stop. With primary force off, the return spring forces the armature back against the energized stop and hence establishes the throttle position and idle speed.
