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. Movement of the vehicle is prohibited by interlocking the SAFETY LOCK with
a switch operated by the foot brake, 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 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 relays has no eff ect on engine operation. This unit
is for vehicles that require 3 independent relays for the
vehicles ignition.
