Designed to route power from the key to the ignition and starter circuits, the Standard Ignition Ignition Starter Switch, part number US-67, is the electrical switch that handles those circuits as the key moves through its positions. It fits many vehicles, among them the 1971-1972 Ford Mustang, 1971-1977 Ford Maverick and 1971-1972 Ford Thunderbird, as a direct-fit replacement for the listed applications. See the "Vehicles it fits" section for the full list.
- Copper alloy conductors: deliver strong electrical conductivity with low resistive losses.
- 100% tested: every switch is checked to verify both its mechanical and its electrical switching performance.
- Quality controlled from start to finish: Standard Ignition is a global manufacturer of original equipment ignition products and keeps control of quality from componentry through the finished product.
- Built for the shop: a robust design and high-grade materials are made to meet the stringent demands of today's service professional.
Standard Ignition builds its full line of ignition switches from carefully chosen materials, aiming for proper fit and function on every install. Signs an ignition switch may need replacing include no crank when the key is turned to start, stalling or intermittent power loss while driving, and dash or accessory functions that cut in and out as the key moves. Diagnose the cause before replacing the switch, because wiring, the battery or the starter circuit can produce the same symptoms.

Frequently Asked Questions
Is this the right Mustang switch for a 1971 or 1972 Ford Mustang?
Yes. US-67 is listed as a direct-fit replacement for the 1971-1972 Ford Mustang, and it also fits other Ford, Lincoln and Mercury models, such as the 1971-1977 Ford Maverick. See the "Vehicles it fits" section for the full list.
Will this work as a Thunderbird switch for a 1971-1972 Ford Thunderbird?
Yes. It is listed as a direct-fit replacement for the 1971-1972 Ford Thunderbird.
What does an ignition starter switch do?
It is the electrical switch that routes power to the ignition and starter circuits as the key moves through its positions. This lets the engine be cranked and kept running.
How is the US-67 built and tested?
Every unit is 100% tested to verify its mechanical and electrical switching performance. Its copper alloy conductors provide strong electrical conductivity with low resistive losses.
What should I know before installing it?
Disconnect the battery before working on ignition wiring, and follow the vehicle service information for removal and installation. First confirm that the switch is the cause of the problem.
