This simple, low cost controller bypasses the ignition switch when activated by the closure of a momentary switch. The operator may then remove the ignition key without shutting the engine down. Move-ment
of the vehicle is prohibited by interlocking the SAFETY LOCK 4 with the brake light switch, a neutral safety switch on the gearshift or a parking brake operated switch. Operating any one of these will cause the
relays in the
SAFETY LOCK 4 to drop out and interrupt the ignition circuit to stop the engine. The authorized operator
need only insert the key and turn on the ignition to operate the vehicle. With the key in the lock and turned
on, the ignition circuit is completed as normal and the opening of the SAFETY LOCK 4 relays has no effect
on engine operation.
The SAFETY LOCK 4 contains 4 relays to permit energizing 3 auxiliary circuits in addition to the ignition switch bypass.
