Standard Ignition US-151 Ignition Switch

Ignition Switch for Column-Mount Applications

Standard Ignition US-151 is a column-mounted ignition switch built with a bolt-on attachment method, a rectangular male connector, and 10 male pin terminals. It is engineered for direct electrical switching performance in older Buick, Oldsmobile, Cadillac, and Pontiac applications that require a precise ignition switch replacement.

With copper alloy conductors and a robust housing made from aluminum and plastic, this ignition switch is built to maintain low-resistance electrical flow and consistent mechanical operation. Standard Ignition US-151 is a direct-fit service part for vehicles such as the Buick Century, Oldsmobile Cutlass Ciera, and Pontiac Bonneville.

• Intermittent accessory or ignition power loss
• Key position failure between OFF, RUN, and START
• Electrical contact wear from age and repeated use
• Switching issues in column-shift and tilt-steering vehicles

Installation Notes and Quality Assurance

Verify connector shape, terminal count, mounting location, and steering-column configuration before installation. This part uses a bolt-on mounting method and a single rectangular male connector, so matching the original switch layout is important for proper operation. Confirm vehicle-specific notes such as tilt steering wheel, pulse wipers, steering lock, console shift, or electronic instrument panel requirements before ordering.

Standard Ignition builds this switch with service-grade materials and tests each unit for both mechanical and electrical switching performance to help ensure proper fit and function.
