The Standard Ignition switch NS-201, a Neutral Safety Switch / Back Up Light Switch, lets the engine crank only in Park or Neutral and switches on the reverse lamps when you shift into Reverse. It is a direct-fit replacement for many vehicles, among them the 1998-2011 Ford Crown Victoria, 1998-2011 Lincoln Town Car and 1998-2011 Mercury Grand Marquis; see the Buyer's Guide tab for the full list.
The part is listed under both names because it does two jobs. It completes the starting circuit only when the gear selector is in Park or Neutral, and it closes the back-up light circuit when Reverse is selected. If a failed neutral safety / back-up light switch is the cause of your problem, NS-201 replaces it.
Signs this switch may need replacing: The engine won't crank in Park or Neutral, it cranks in a drive gear, or the back-up lights stay off in Reverse. Other faults can cause these symptoms, so diagnose the cause before replacing the switch.
