Standard Ignition US-67 Ignition Switch

Ignition Switch for Column-Mount Applications

Standard Ignition US-67 is a column-mounted ignition switch built for direct electrical switching performance in classic Ford, Lincoln, and Mercury applications. It uses copper alloy conductors for strong conductivity and low resistive loss, with a robust construction aimed at consistent fit and function.

Compatible with select 1971-1979 Lincoln Continental and 1971-1972 Ford Mustang, Thunderbird, and Mercury Cougar applications, this ignition switch is a practical replacement for worn or intermittent original units. The US-67 part number is also a useful reference when verifying interchange and catalog lookup.

Key Features

• Column-mounted ignition switch with bolt-on attachment method
• 1 rectangular female connector
• 7 male pin terminals
• Copper alloy conductors for low-resistance electrical transfer
• Built with tested mechanical and electrical switching performance
• Direct replacement format for select Ford, Lincoln, and Mercury vehicles

Detailed Description

Standard Ignition US-67 is engineered as an ignition switch replacement for vehicles that use a column-mounted, rectangular-connector design. The switch is constructed from high-grade materials to maintain proper fit and function, while the copper alloy conductor design supports stable current flow through the ignition circuit. For buyers searching for a 1971 Ford Mustang ignition switch, a 1971-1972 Ford Thunderbird ignition switch, or a 1971-1972 Mercury Cougar ignition switch, US-67 provides a cataloged match for those applications. It also applies to 1971-1979 Lincoln Continental models.

This part cross-references Standard Ignition LS406 for the same application.

What It Helps Fix

• Intermittent no-start conditions caused by a failing ignition switch
• Electrical contact wear that affects key-on power delivery
• Ignition circuit issues related to heat, corrosion, or internal switch wear
• Problems with accessory, run, or start circuit switching
• Fitment issues when replacing a damaged column-mounted switch

Installation Notes and Tips

Verify the connector style, terminal count, and column mounting layout before installation. This switch uses a female rectangular connector, male pin terminals, and a bolt-on attachment method, so matching the original configuration is important for proper installation. Confirm vehicle application by year, make, and model before ordering, especially on classic Ford Mustang, Thunderbird, Cougar, and Lincoln Continental platforms.

Quality Assurance

Standard Ignition states that these switches are 100% tested for mechanical and electrical switching performance. The design uses durable materials and copper alloy conductors to support reliable operation in service.
