Designed to deliver key-on power and starter engagement when you turn the key, the Standard Ignition Ignition Starter Switch, part number US-274, is the electrical switch that routes power to the ignition and accessory circuits and energizes the starter circuit in the start position. It fits many vehicles, among them the 1995-1997 Ford Explorer, 1995-1998 Ford E-350 Econoline and 2003-2004 Ford E-150, as a direct-fit replacement for the listed applications. See the Buyer's Guide tab for the full list and engine details.
Signs this switch may need replacing include an engine that won't crank when the key is turned to start, stalling or sudden power loss while driving, and accessories or dash lights that cut out or flicker as the key moves. Other faults can cause the same symptoms, so diagnose the circuit before you replace the switch.
