Facet Neutral Safety Switch

The Facet Neutral Safety Switch (also called a neutral start switch, park/neutral position switch, or inhibitor switch) helps prevent an automatic-transmission vehicle from starting unless the transmission is in Park or Neutral. This protects against unintended vehicle movement at startup.

Key Features:

• Opens and closes the starter circuit based on the selector position, so the engine cranks only in Park or Neutral
• Often supplies the signal that turns on the backup lamps when Reverse is selected, depending on the application
• Built as a direct-replacement part, so it restores original function without modification
• Made by Facet, a long-established supplier of automotive replacement parts for the aftermarket
• Uses a sealed housing and electrical contacts built to handle heat, vibration, and fluid exposure around the transmission

A worn or failing neutral safety switch can cause no-start or intermittent starting, a vehicle that starts in gear, backup lights that don't work, or a gear indicator that doesn't match the selector. Replacing it restores reliable starting and safe operation. Choose the child item that matches your application.
