Standard Ignition Ignition Switch P/N:US-278
Keep your ignition system switching cleanly with the Standard Ignition Ignition Switch (US-485), a direct-fit replacement for the 1997-2004 Chevrolet Corvette (see the "Vehicles it fits" section for engine-specific applications). This ignition/starter switch handles the electrical switching that routes power to the run and start circuits when you turn the key, so a worn or intermittent original can be replaced with a fresh unit.
Signs the original switch may need replacing include no crank or no start when turning the key, intermittent power loss to accessories, or a key that must be jiggled to make contact. Diagnose the cause before replacing, since these symptoms can have other sources.
