Standard Ignition Ignition Switch P/N:US-637
Standard Motor Products
Designed to send power to the right circuits each time you turn the key, the Standard Ignition Ignition Starter Switch, part number US-351, is the electrical switch that feeds the ignition and starter circuits as the key moves through its positions. It fits many vehicles, among them the 2002-2005 Dodge Ram 1500, 2003-2005 Dodge Ram 2500 and 2001-2006 Dodge Dakota, as a direct-fit replacement for the listed applications. See the "Vehicles it fits" section for the full list and engine details.
If a failing ignition switch is behind a no-crank condition, stalling, or accessories and dash lights that cut out when the key is moved, this switch replaces it. Diagnose the cause before replacing, because these symptoms can also come from other parts of the starting and ignition system.
