ABSTRACT:
An ignition-powered interlock switch is provided for disabling a low oil pressure switch in power-driven apparatus such as lawn mowers, pumps, generators, tractors and the like. The interlock switch disables the low oil pressure switch when the engine is not running to permit the engine to be easily started. The interlock switch preferably comprises a diode, a relay, and a capacitor connected in parallel with the relay solenoid. The capacitor discharges through the relay solenoid after the engine stops running to operate the relay. The interlock switch may also include either a manual or an electronic switch.
