Built for Reliable Starting Circuit Control

This ignition switch is engineered to restore proper key-to-starter operation in vehicles that rely on a column-mounted switch assembly. Standard Ignition uses high-grade materials and copper alloy conductors to support consistent electrical conductivity and dependable switching action. Part number US-277 is a direct-fit service replacement for many Dodge Ramcharger, B150, B250, B350, D150, D250, D350, W150, W250, W350, D100, and W100 applications with tilt steering wheel configurations.

This part cross-references Standard Motor Products (e.g., US-277, 1S6277) for the same application.

Installation Notes and Quality Control

Verify the vehicle uses a tilt steering wheel and confirm the connector style, terminal count, and column mounting location before installation. Match the original switch layout to the 1 rectangular female connector and 11 blade terminals to ensure proper indexing on the steering column. Standard Ignition tests each switch for mechanical and electrical performance before release.
