Description

Keep power flowing to your starter, ignition, and accessory circuits with the Standard Ignition Ignition Switch (US-173), an ignition starter switch that directs battery voltage to the correct circuits as you turn the key through its off, accessory, run, and start positions. It installs as a direct-fit replacement for the 1990-1993 Toyota Celica and 1991-1995 Toyota MR2 — see the "Vehicles it fits" section for engine-level fitment.

Copper alloy conductors: deliver strong electrical conductivity with low resistive losses.
Quality-controlled build: made by a global manufacturer of original-equipment ignition products, with control maintained from componentry through finished product.
100% tested: each switch is checked to verify both mechanical and electrical switching performance.
Robust materials: built with high-grade materials to meet the demands of today's service professional.

Signs the original switch may need replacing include a no-crank condition, intermittent power loss to accessories, or a key that has to be wiggled to start or run the engine — diagnose the cause before replacing, since these symptoms can have other sources. If the ignition switch is the fault, this unit restores proper switching for the listed applications.
