Neutral Safety Switch

An automotive neutral safety switch is a device found in vehicles equipped with automatic transmissions. Its primary function is to prevent the engine from starting unless the transmission is in either the "Park" or "Neutral" position. You may be asking, "where is the neutral safety switch located?". The neutral safety switch is typically located on the transmission housing or shifter assembly, and it is activated when the driver shifts the transmission into either Park or Neutral. When activated, the switch sends an electrical signal to the engine control module or starter (on older vehicles), which allows the engine to start. If the switch is malfunctioning or not properly adjusted, the engine may not start, or it may start in gear, which can be dangerous. The neutral safety switch is a critical safety component that prevents accidents and damage to the vehicle by ensuring that the engine can only start in a safe position.
