Help keep the starter from engaging unless the transmission is in Park or Neutral with the Standard Ignition Neutral Safety Switch NS-94. It is a direct-fit replacement for the listed applications, including the 1989-1996 Ford F-150, 1989-1996 Ford F-250, 1989-1997 Ford F-350, 1990-1996 Ford Bronco, 1990-1997 Ford E-150 Econoline and 1995-1997 Ford F-53 Motorhome Chassis. See the "Vehicles it fits" section for the full list of years, models and engines.
A neutral safety switch sits in the starting circuit and interrupts it unless the transmission is in Park or Neutral. Standard Ignition is a global manufacturer of original equipment ignition products. It maintains complete quality control throughout the manufacturing process, from componentry to the finished switch.
- Copper alloy conductors: designed for superior electrical conductivity with low resistive losses.
- 100% tested: each switch is checked to verify both its mechanical and electrical switching performance.
- Robust build: a robust design and high-grade materials made for the stringent demands of today's service professional.
- Technician-focused engineering: backed by decades of industry-leading research and development centered on the technician's needs.
Signs this part may need replacing: the engine won't crank in Park or Neutral, cranks only after the shifter is moved or jiggled, or cranks with the transmission in gear. Other starting-system faults can cause similar symptoms, so diagnose the cause before replacing the switch.

Frequently Asked Questions
What does a neutral safety switch do?
It interrupts the starting circuit unless the transmission is in Park or Neutral. The starter is designed to engage only in those positions.
Which vehicles does the Standard Ignition NS-94 fit?
Listed applications include the 1989-1996 Ford F-150 and F-250, the 1989-1997 Ford F-350, the 1990-1996 Ford Bronco and several Ford Econoline models. See the "Vehicles it fits" section for every year, model and engine.
Is the NS-94 tested before it ships?
Yes. Standard Ignition 100% tests its switches to verify both mechanical and electrical switching performance.
What are signs of a failing neutral safety switch?
Common signs are no crank in Park or Neutral, a start only after jiggling the shifter, or the engine cranking in gear. Other starting-system faults can cause these, so diagnose the cause before replacing.
What part numbers does the NS-94 interchange with?
It interchanges with numbers including 2-8825, S9192, F433, NS6528, SW5978, E9TZ7A247A and F5TZ7A247A. The Interchange line in the description gives the complete list.
