Abstract

An automotive shifter interlock in which a slidable shift lever release member is mechanically locked in a shift-release-inhibit position by the combination of an electromagnet bolt and an ignition switch bolt. The ignition switch bolt mechanically locks the electromagnet bolt in a position locking the shift lever release member even though no power is supplied to the electromagnet. After the ignition switch is closed and the ignition switch bolt withdrawn, the electromagnet continues to provide an electromagnetic lock until the brake pedal is depressed.
