Standard Ignition Neutral Safety Switch P/N:NS-53
Keep the starter from cranking unless the shifter is where it should be with the Standard Ignition Neutral Safety Switch, part number NS-7. This switch is designed to let the engine crank only when the transmission selector is in Park or Neutral, helping prevent the vehicle from starting while in gear. It is a direct-fit replacement for many vehicles, among them the 1967-1968 Chevrolet Impala, 1967-1968 Chevrolet Camaro and 1967-1969 Chevrolet Bel Air. See the Buyer's Guide tab for the full list of applications.
Signs a neutral safety switch may need replacing include an engine that will not crank in Park or Neutral, one that cranks only after the shifter is jiggled, an intermittent no-crank condition, or an engine that cranks with the selector in a drive gear. Because other starting-circuit faults can cause similar symptoms, diagnose the cause before replacing the switch.
