Standard Ignition NS683 neutral safety switch for the 2004-2009 Toyota Prius is an electrically operated switch that replaces a damaged unit. It restores neutral safety function and supports road safety.
When a neutral safety switch wears out, the car may not start in Park or Neutral, or it may start when it should not. These signs alone do not prove the switch is at fault, since a weak battery can also keep a car from starting.
This switch is a direct-fit replacement for the 2004-2009 Toyota Prius, made to OE spec for fit, form and function. The 2004-2009 Toyota Prius takes one, and this listing is a single switch.
