The ignition starter switch is the electrical switch operated by the ignition key. Depending on key position, it feeds power to the matching circuits and signals the starter to crank. Signs this part may need replacing include no crank when the key is turned to start, accessories or gauges that lose power, or intermittent stalling. These symptoms can have other causes, so diagnose the circuit before replacing. If a failed switch is the cause, the US-447 replaces it.
