Description

The Standard Ignition NS-377 Neutral Safety Switch is a direct-fit replacement designed for reliable electrical performance in Chevrolet and GMC heavy-duty trucks. This switch prevents the vehicle from starting in gear, ensuring safety by only allowing ignition when the transmission is in Park or Neutral. It features a robust construction with aluminum and plastic components finished in black and silver for durability and corrosion resistance. The switch includes a single female connector and 11 male blade terminals for seamless integration with the vehicle's electrical system. Its bolt mount design ensures a secure attachment to the transmission housing.
