This simple, low cost controller bypasses the ignition
switch when activated b y the closure of a momentary
switch. The oper ator ma y then remo v e the ignition k e y
without shutting the engine down. Mo vement of the
vehicle is prohibited by interlocking the SAFETY LOCK
with a switch operated by the f oot brak e , a neutr al
safety switch on the gearshift or a parking brak e
operated switch. Operating any one of these will cause
the relay 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 k e y in the loc k
and turned on, the ignition circuit is completed as
normal and the opening of the SAFETY LOCK relay
has no effect on engine operation.
