Abstract
A control device for a brake/transmission/ignition interlock for a motor vehicle. The control device includes an electromagnetic device conditioned in response to application of the brake, a release mechanism operative in response to the condition of the electromagnetic device to allow movement of the shift lever out of the park position to an operating position, and a control switch operative in response to movement of the shift lever out of the park position to place the ignition switch in the lock condition. The control device includes a lead frame formed of a flat conductive metal stock and stamped and configured to define the control switch and a plurality of leads. The control switch has a first position in which the leads coact to establish a circuit to the electromagnetic device and a second position in which the circuit to the electromagnetic device is interrupted and the leads coact to establish a circuit to the ignition switch to place the ignition switch in its locked condition and thereby preclude removal of the ignition key. The switch is moveable between its first and second positions in response to movement of the shift lever out of the park position.
