The Ignition Node Module (IGNM) incorporates an integral ignition switch that consists of four rotary positions with three detent positions and one spring-loaded position. The one extreme clockwise position is a spring-loaded momentary contact "START" position. When released from the "START" position, the switch will automatically return to the detent "RUN" position. The other position includes a detent "ACCESSORY" position and a detent "OFF" position.
