Standard Ignition Clutch Starter Safety Switch P/N:NS-63
Designed to keep the starter circuit open until the clutch pedal is pressed, the Standard Ignition Clutch Starter Safety Switch, part number NS-147, is the pedal-actuated switch in the starting system of a manual-transmission vehicle. It fits many vehicles, among them the 1998-2001 Ford Explorer, 1998-2011 Ford Ranger and 2001 Ford Explorer Sport Trac, and is a direct-fit replacement for the listed applications. See the "Vehicles it fits" section for the full list and engine details.
The clutch pedal operates this switch, which lets the starter engage only when the pedal is depressed. This helps prevent the engine from cranking while the transmission is in gear.
Signs this part may need replacing include:
Diagnose the starting circuit before replacing parts.
