Abstract
An electrical switch has three terminals, one that is always connected to one side of an LED and in parallel to a resistor. A rocker slides a movable contact to and from an engine OFF or kill position, from and to an engine RUN position. An oil detector circuit uses the engines magneto system to light the LED when the switch is in the RUN position and the engine is rotated. The flashing LED provides a visual indication of low oil in the engine.
