Standard Ignition Ignition Switch P/N:US-433

When a turn of the key should mean a crank, the Standard Ignition switch US-433 is the ignition starter switch built to handle that job. It is a direct-fit replacement for the 2000-2005 Buick LeSabre. See the Buyer's Guide tab for engine details.

The ignition starter switch sends battery power to the vehicle's accessory, ignition, and starter circuits as the key moves through its positions, including the start position that engages the starter.
