Standard Ignition US-105 Ignition Switch

Ignition Switch for Tilt-Column Applications

Standard Ignition US-105 is an ignition switch built for column-mounted applications that demand consistent electrical switching and a precise mechanical fit. It uses copper alloy conductors for strong conductivity and low resistive loss, and each unit is tested for mechanical and electrical performance before release.

For repair work on classic and late-model GM, Jeep, and Dodge platforms, US-105 is a direct replacement choice for many tilt-steering-wheel vehicles, including Chevrolet Camaro, Corvette, Blazer, and GMC truck and van applications.

Key Features

• Column-mounted ignition switch with bolt-on attachment method
• Female 1-connector design with rectangular connector shape
• 9 male blade terminals for secure electrical connection
• Copper alloy conductors for low-resistance current flow
• 100% tested for mechanical and electrical switching performance
• Built with high-grade materials for service-professional use

Detailed Description

The Standard Ignition US-105 ignition switch is engineered for vehicles that use a steering-column-mounted switch, especially tilt-column setups found across many Chevrolet, GMC, Buick, Pontiac, Jeep, Cadillac, and Dodge models. The part number US-105 is commonly searched for replacement work on vehicles such as the Chevrolet Camaro, Chevrolet Corvette, and GMC Jimmy, where reliable key-to-start operation and accessory power switching are critical.

This ignition switch is designed to restore proper switching action when the original unit shows wear, intermittent contact, or mechanical failure. Its copper alloy conductor construction supports stable electrical transfer, while the tested switch mechanism helps ensure consistent operation across ignition positions.

This part cross-references Standard Ignition US105T for the same application.

Common Problems It Can Help Resolve

• No-crank or intermittent crank conditions caused by worn switch contacts
• Accessory power loss when turning the key through ignition positions
• Hard-start complaints related to inconsistent ignition switching
• Electrical interruptions in column-mounted ignition circuits
• Key position issues caused by mechanical wear in the switch assembly

Installation Notes and Fitment Tips

Fits 1990-2002 Chevrolet Camaro, N/A. Fits 1988-1996 Chevrolet Corvette, N/A. Fits 1987-1995 Chevrolet Astro, N/A, compatible with vehicles with tilt steering wheel. Fits 1987-1995 GMC Safari, N/A, compatible with vehicles with tilt steering wheel. Fits 1987-1995 Jeep Wrangler, N/A, compatible with vehicles with tilt steering wheel.

Additional fitment includes many Chevrolet and GMC C/K trucks, S10 and S10 Blazer models, full-size vans, and select Buick, Cadillac, Oldsmobile, and Pontiac vehicles listed in the application data. Review the steering column configuration and connector style before installation, especially on vehicles noted with tilt steering wheel, column shift, or console-shift exclusions.

Because this is a column-mounted switch, confirm the connector gender, terminal count, and mounting location against the original part before replacement. On applications with specific notes such as metal locking connector tabs or console-shift exclusions, match those details exactly for proper fit.

Quality Assurance

Standard Ignition builds this switch with robust materials and copper alloy conductors to support dependable electrical performance. Each US-105 unit is 100% tested to verify both mechanical operation and electrical switching function before it reaches service use.
