ABSTRACT:
An ignition switch system is provided for use with an engine of a vehicle. The ignition switch system includes a power source such as a battery, and an ignition switch connected to the power source. The ignition switch includes an off position and a combined run and start position. A controller is electrically connected to the ignition switch. A relay mechanism is electrically connected to the controller. A starter mechanism is electrically connected to the relay mechanism and is drivingly engageable with the engine of the vehicle. The ignition switch connects the power source to the controller when the ignition switch is in the combined run and start position. The controller, upon connection with the power source, determines if the engine is running. If the engine is not running, the controller activates the relay mechanism which engages the starter mechanism to the power source. If the controller determines that the engine is running, the controller deactivates the relay in order to disable the starter mechanism.
