Standard Ignition Neutral Safety Switch P/N:NS727
Keep the starter circuit safe and predictable with the Standard Ignition Neutral Safety Switch NS779, a direct-fit replacement for the 1999-2005 Mazda Miata. A neutral safety switch signals the starter circuit to permit cranking only when the transmission is in Park or Neutral; on many applications it also feeds the back-up lamp circuit. If a worn or failed switch is the cause of a no-crank condition or a starter that engages in the wrong gear, NS779 replaces it.
Signs this switch may need replacing include an engine that won't crank in Park or Neutral, a starter that only works when you jiggle the shifter, or cranking in an unintended gear. Diagnose the cause before replacing, since these symptoms can have other sources. See the Buyer's Guide tab for engine-specific fitment on your Miata.
