  • Made to OE spec: built to the original specification for proper fit, form and function.
  • Direct-fit replacement: an electrically operated switch designed to take the place of a damaged OE ignition switch.

The ignition starter switch is the electrical switch that sends power to the ignition, accessory and starter circuits for each key position. Signs it may need replacing include a no-crank or intermittent-crank condition, the dash or accessories cutting out, or the engine stalling when the key is moved. Because these symptoms can have other causes, diagnose the circuit first. If the original switch is at fault, US-937 replaces it.
