ABSTRACT:
Sensors such as switches are arranged to detect the insertion of a key into a key cylinder, the rotation of the key to one or more operative positions, the position of a transmission shift level, the depressions of a brake pedal and the like, and to produce signals which are processed by logic circuits in a manner to determine the energization mode and timing of the solenoid or the like motor arrangement in a manner which locks or releases a safety button which must be pressed before the steering column of a vehicle can be locked. The mechanism which performs the locking operation is mounted on the exterior of the housing in which the key cylinder is disposed, thus facilitating assembly.
