Standard Ignition US-274 Ignition Switch

Ignition Switch for Ford E-Series and Explorer

Standard Ignition US-274 is an ignition switch built for Ford E-Series vans and select Explorer and Mountaineer applications. It uses a bolt-on, column-mounted design with a square female connector and 11 male blade terminals for a direct-service replacement.

Key Features

• Column-mounted ignition switch with bolt-on attachment method
• Square female connector with 11 male blade terminals
• Copper alloy conductors for strong electrical conductivity and reduced resistive loss
• Built with high-grade materials for consistent fit and function
• 100% tested for mechanical and electrical switching performance

Detailed Description

Standard Ignition US-274 is engineered for service replacement on Ford E-150, E-250, E-350, Econoline, Explorer, and Mercury Mountaineer vehicles. The switch is built with durable materials and copper alloy conductors to support reliable current transfer through the ignition circuit. For buyers searching for a Ford E-150 ignition switch, Ford E-250 ignition switch, or Ford E-350 ignition switch, this part number provides a fitment-focused solution for column-mounted applications. This part cross-references F5TZ11572A and UL7-23 for the same application.

What It Helps Fix

• Intermittent no-start conditions caused by worn switch contacts
• Ignition key positions that do not respond consistently
• Electrical switching faults in the column ignition circuit
• Starting issues related to poor terminal contact or internal wear
• Accessory or run-position power loss from a failing ignition switch

Installation Notes and Tips

Verify connector shape, terminal count, and column mounting before installation. Confirm vehicle year and model against the fitment list for 1995-2004 Ford E-Series applications, plus 1995-1997 Ford Explorer and 1997 Mercury Mountaineer. Match the existing switch layout to the 11-terminal blade configuration and inspect the harness connector for heat damage or corrosion before reconnecting.

Quality Assurance

Standard Ignition builds this switch with robust materials and tests each unit for mechanical and electrical switching performance. The design uses copper alloy conductors to help maintain stable conductivity in service.
