Abstract
A positive off and automatic on ignition stop switch and electronic circuit for use in an internal combustion engine. The circuit that allows for normal operation of the engine in an unbiased state. When it is desired to turn the engine off, a stop switch is triggered which provides a single mechanism for shutting off the engine. After the switch is activated, the circuit holds the ignition circuit in an off state for a sufficient amount of time to allow the engine to completely stop operation. The circuit holds the engine in the off state for a period of time even after the switch is deactivated. As a result, the operator of a piece of equipment in which the present invention is utilized can activate a switch one time, which results in the engine coming to a complete stop, without the requirement of further activity.
