Airtex 1S17735 Neutral Safety Switch

The Airtex 1S17735 is a direct-fit replacement neutral safety switch designed to restore proper starting circuit function on automatic transmission-equipped vehicles. Also referred to as a park/neutral position switch or inhibitor switch, this component is a critical part of the ignition and starting system.

How It Works:

The neutral safety switch prevents the engine from cranking unless the transmission is in Park or Neutral. This protects against accidental engine starts while the vehicle is in gear, reducing the risk of unintended movement. When the switch fails due to age, wear, or corrosion, the vehicle may not start at all, start intermittently, or start in gear — all signs that replacement is needed.

Key Features:

• Direct OEM replacement design for accurate fit and function
• Engineered to match original equipment electrical specifications
• Designed to accept the factory wiring connector without modification
• Manufactured by Airtex Automotive Division, an ISO/TS 16949-certified supplier
• Helps restore proper park/neutral start lockout and, where applicable, backup lamp function

The Airtex 1S17735 neutral safety switch is built to meet or exceed the performance standards of the original part it replaces, providing reliable ignition system protection.
