The Standard Motor Products US265 Ignition Switch functions like a standard automotive ignition switch, controlling various electrical circuits in your vehicle. The typical positions are:

• ACC (Accessory): Allows power to certain accessories (e.g., radio, power windows) without turning on the engine.
• ON/RUN: Powers the vehicle's ignition system, fuel pump, and other essential components. All dashboard warning lights illuminate briefly. This is the position for normal driving.
• START: Momentary position that engages the starter motor to crank the engine. The key automatically returns to the "ON/RUN" position once released.

Always ensure the vehicle is in Park (P) or Neutral (N) before attempting to start the engine.
