Turn the key with confidence using the Standard Ignition Ignition Switch (US-301, also written US301), the electrical switch that directs power from the key cylinder to the starter and ignition circuits. It installs as a direct-fit replacement for the 1991-1995 Ford Escort and 1991-1996 Mercury Tracer — see the Buyer's Guide tab for engine-level details.
- Copper alloy conductors: provide strong electrical conductivity with low resistive losses.
- 100% tested: each switch is verified for both mechanical and electrical switching performance.
- Robust materials: high-grade construction built to meet the demands of professional service.
- OE ignition experience: produced by a global manufacturer of original-equipment ignition products with quality control from componentry to finished part.
Signs the original switch may need replacing include intermittent starting, accessories or dash lights cutting out as the key is turned, or a key position that no longer reliably energizes the starter or ignition circuit. Because these symptoms can have other causes, diagnose the fault before replacing. If a failed ignition switch is the cause, this unit restores the switching function on the listed applications.
