Standard Ignition Neutral Safety Switch P/N:NS-312
Help make sure your engine cranks only in Park or Neutral with this Standard Ignition switch, the NS-25 Neutral Safety Switch. It fits many vehicles, among them the 1986-1990 Ford Taurus, 1984-1989 Ford Tempo and 1984-1990 Ford Escort, as a direct-fit replacement for the listed applications. See the Buyer's Guide tab for the full list.
A neutral safety switch senses the transmission's gear position and closes the starting circuit only when the selector is in Park or Neutral. If a worn original switch is the cause of a no-crank or intermittent-start condition, this switch replaces it.
Signs a neutral safety switch may need replacing include the engine not cranking in Park, cranking only in Neutral, or starting intermittently. These symptoms can have other causes, so diagnose the starting circuit before replacing the switch, and follow the vehicle service information for installation and any adjustment.
