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 "Vehicles it fits" section 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.
- Quality control: Standard Ignition is a global manufacturer of original equipment ignition products and maintains complete quality control throughout manufacturing, from componentry to finished product.
- Copper alloy conductors: Designed for superior electrical conductivity with low resistive losses.
- 100% tested: Every switch is tested to verify both mechanical and electrical switching performance.
- Robust design: High-grade materials are built for the stringent demands of today's service professional, backed by decades of research and development focused on what technicians need.
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.

Frequently Asked Questions
Is this the right Taurus switch for a 1986-1990 Ford Taurus?
Yes. The NS-25 is listed as a direct-fit replacement for the 1986-1990 Ford Taurus. Check the "Vehicles it fits" section to see the other listed vehicles.
Can I use this as a Tempo switch on a 1984-1989 Ford Tempo?
It is listed for the 1984-1989 Ford Tempo and the 1984-1990 Ford Escort, along with other vehicles shown in the "Vehicles it fits" section.
What does a neutral safety switch do?
It lets the starting circuit close only when the automatic transmission is in Park or Neutral. It is intended to prevent the engine from cranking while the vehicle is in gear.
What are signs the neutral safety switch may need replacing?
Common signs include no crank in Park, cranking only in Neutral, or intermittent starting. These can have other causes, so diagnose the starting circuit before replacing the switch.
How is the Standard Ignition NS-25 tested?
Standard Ignition tests 100% of these switches to verify both mechanical and electrical switching performance. The switch uses copper alloy conductors for low resistive losses.
