Standard Ignition US-650 Ignition Switch

Ignition Switch for GM Column-Mount Applications

Standard Ignition US-650 is a column-mounted ignition switch built for direct replacement service on select Chevrolet, Pontiac, and Saturn vehicles. It is engineered with copper alloy conductors for strong electrical transfer and low resistance, with mechanical and electrical testing performed before release.

Key Features

• Bolt-on attachment method for secure column installation
• Female square connector with 1 connector interface
• 5 male pin terminals for the specified electrical layout
• Column mounting location for ignition switch replacement service
• Built with high-grade materials for fit and function
• Copper alloy conductors to support consistent conductivity

Product Details

This ignition switch is designed for vehicles that use a column-mounted, bolt-on switch assembly and a square female connector. Standard Ignition US-650 is a practical replacement for worn or failing switch units in 2004-2012 Chevrolet Malibu, 2005-2010 Pontiac G6, and 2007-2009 Saturn Aura applications. The part number US-650 is also referenced in service catalogs under related interchange numbers for the same application, including 1S8481 and CS1010.

What It Helps Fix

• Intermittent or no-start conditions caused by switch wear
• Accessory power loss when the key is turned
• Ignition key position issues during crank or run operation
• Electrical switching faults at the steering column
• Problems traced to a damaged or worn ignition switch assembly

Installation Notes

Verify connector shape, terminal count, and mounting style before installation. This part uses a bolt-on attachment method, mounts on the column, and uses a female square connector with 5 male pin terminals. Confirm vehicle-specific fitment for 2004-2012 Chevrolet Malibu, 2005-2010 Pontiac G6, and 2007-2009 Saturn Aura before service. The part number US-650 should be matched to the original switch configuration during diagnosis and replacement.

Quality Assurance

Standard Ignition builds this switch with robust materials and tests each unit for mechanical and electrical switching performance before it leaves production. The design uses copper alloy conductors to support reliable conductivity and reduced resistive loss.
