ABSTRACT:
An ignition key-brake interlock for a transmission gear shifter includes a gear and actuator having teeth in meshing engagement, a lever whose rotation is prevented or limited depending upon the position of the actuator, a pivotably mounted cam on a gear selector, a cable assembly connecting the ignition key lever to the cable and electrical solenoid through which the cable assembly passes, and a gear selector shaft movable by the vehicle operator among several gear range detent positions. An electrical power source is connected to the solenoid when the ignition switch is turned to run or start, and is disconnected when a brake pedal is depressed. A button, crimped to the cable, moves freely within the solenoid and into contact with plunger, which is magnetically held on a seat when the electric circuit is closed.
