Keep the starter from engaging until it's safe to crank with the Standard Ignition Clutch Starter Safety Switch / Neutral Safety Switch (NS-35). This switch acts as the safety interlock in the starter control circuit, completing that circuit only when the clutch pedal is depressed on manual-transmission vehicles or the shifter is in Park or Neutral on automatics — so the engine won't crank in gear. It's a direct-fit replacement for the listed applications, including the 1987-2002 Chevrolet Camaro, 1988-1996 Chevrolet C1500 and K1500, 1988-1995 Chevrolet S10, 1997-2003 and 2007 Chevrolet Corvette, 1987-1992 and 2001-2002 Pontiac Firebird, 1995-2005 Pontiac Sunfire, and many Saturn models (SL, SL1, SL2, SC1, SW2, VUE) — see the Buyer's Guide tab for the full list.
This part is cataloged under both names — clutch starter safety switch and neutral safety switch. Signs the original may need replacing include a no-crank condition even with the clutch fully depressed or the shifter in Park/Neutral, or the more serious sign of the engine cranking while in gear. A no-crank can have other causes, so diagnose the switch before replacing; if a failed safety switch is the cause, this NS-35 replaces it.
