(You save)
Keep your engine from cranking unless the clutch is fully pressed with the Standard Ignition Clutch Starter Safety Switch NS-508. Mounted at the clutch pedal, this switch closes the starter circuit only when the pedal is depressed, so the starter can't engage while the vehicle is in gear. It installs as a direct-fit replacement for the 2011-2014 Mazda 2 and the 2004-2013 Mazda 3 — see the Buyer's Guide tab for engine-level fitment on the listed applications.
Direct-fit OE replacement: designed to drop into the factory location for straightforward installation.
Built for the environment: high-quality materials chosen to withstand extreme conditions under the pedal assembly.
Tested for reliability: undergoes extensive testing before it ships.
Quality-controlled build: produced under complete quality control throughout manufacturing.
Signs the original switch may need replacing include a no-crank condition even with the clutch fully depressed, or an engine that cranks without the clutch pressed. Because a no-start can have several causes, diagnose the circuit before replacing; if a failed clutch starter safety switch is the cause, this restores the intended crank-inhibit function.
This part cross-references / interchanges with the following part numbers:
S41290, SW5521, NS6726, BP4K6649YA, NS-508
