Detailed Description

Standard Ignition US-583 is an ignition switch for Ford E-Series vans, Ford Freestar, and Ford Taurus applications that require a column-mounted, bolt-on switch with a rectangular female connector. The switch is engineered with copper alloy conductors to reduce electrical resistance and support reliable switching action. For service work on a Ford E-150, E-250, or E-350 Super Duty, this part number provides a direct-fit replacement option that matches the original connector and terminal layout.

Common Replacement Reasons

• Intermittent no-start condition caused by worn switch contacts
• Accessory or ignition circuits that lose power unexpectedly
• Key position issues when turning from OFF to START
• Electrical switching faults traced to the column ignition switch
• Replacement after contact wear or internal switch failure

Installation Notes and Tips

Verify the connector shape, terminal count, and column mounting style before installation. Confirm the vehicle application by year and model, especially on Ford E-Series and Taurus platforms, to ensure the switch matches the original electrical and mechanical layout. Inspect the harness connector and column components for heat damage or corrosion before installing the new switch.

Quality Assurance

Standard Ignition states that this switch is built from durable materials and tested for mechanical and electrical performance to help ensure proper operation in service.
