Help keep the starter from engaging while the vehicle is in gear with the Standard Ignition Neutral Safety Switch, part number NS-129. It is designed to let the starting circuit close only when the transmission is in Park or Neutral. It fits many vehicles, among them the 1997-2014 Ford F-150, 1997-2010 Ford Explorer and 1997-1999 Ford F-250, as a direct-fit replacement for the listed applications. See the "Vehicles it fits" section for the full list.
- Copper alloy conductors: intended to deliver strong electrical conductivity with low resistive losses.
- 100% tested: each switch is checked to verify both its mechanical and electrical switching performance.
- Quality-controlled production: built by experienced professionals under a complete quality control process, from the individual components through to the finished product.
- Robust build: a sturdy design and high-grade materials are made to meet the stringent demands of today's service professional.
A neutral safety switch senses the gear-selector position and tells the starting system whether the engine may crank. It may need replacing if the engine cranks in Neutral but not in Park, will not crank at all, or starts only intermittently. Diagnose the starting circuit first, because other components can cause the same symptoms.

Frequently Asked Questions
What does a neutral safety switch do?
It is designed to let the starter circuit engage only when the transmission is in Park or Neutral. This helps prevent the engine from cranking while the vehicle is in gear.
Is this Explorer switch the right fit for a 1997-2010 Ford Explorer?
Yes. NS-129 is listed as a direct-fit replacement for the 1997-2010 Ford Explorer. The "Vehicles it fits" section shows the complete application chart.
Does it fit the 1997-2014 Ford F-150 and 1997-1999 Ford F-250?
It is listed for the 1997-2014 Ford F-150 and the 1997-1999 Ford F-250. Check the "Vehicles it fits" section for the full list of vehicles.
What are signs a neutral safety switch may need replacing?
Common signs are an engine that cranks in Neutral but not in Park, no crank at all, or intermittent starting. Diagnose the starting circuit first, since other parts can cause these symptoms.
Is the switch tested before it ships?
Yes. Standard Ignition states that its parts are 100% tested to verify both their mechanical and electrical switching performance.
