Replace a worn key-start switch on your classic Ford, Lincoln or Mercury with the Standard Ignition switch US-45, an ignition starter switch that routes power to the ignition and starter circuits as the key is turned. It is a direct-fit replacement for the 1968-1969 Ford Mustang and 1969-1970 Ford E-100 Econoline, along with many other classic Ford, Lincoln and Mercury cars, trucks and vans. See the Buyer's Guide tab for the full list of applications.

  • Quality control from start to finish: Standard Ignition, which also builds original equipment ignition products, keeps quality control in-house from the individual components through to the finished switch.
  • Copper alloy conductors: Provide strong electrical conductivity with low resistive losses.
  • Built for proper fit and function: Standard's ignition switch line is constructed from quality materials and designed to fit and work as intended on the listed applications.
  • 100% tested: Every switch is checked for both mechanical and electrical switching performance.

Its robust design and high-grade materials are intended for the demands of professional technicians. Signs this part may need replacing include no crank when the key is turned to start, loss of power while driving, or no power in the run position. If a failed ignition switch is the cause, the US-45 replaces it; diagnose the circuit first, since wiring or starter faults can cause similar symptoms.

What are signs an ignition switch may need replacing?
