Abstract
A brake-shift interlock unit includes a pair of coils which are disposed in a coaxial relationship. A plunger is movable in a passage which extends through the coils. Upon actuation of a vehicle ignition switch, while a brake switch remains in an unactuated condition, a plunger pull coil is energized to move the plunger from the extended position to the partially retracted position. At this time, the plunger engages a stop member. Upon actuation of the vehicle brake, a stopper hold coil is de-energized to enable a shift lever to move.
