Help keep the starter locked out unless the shifter is in Park or Neutral with the Standard Ignition Neutral Safety Switch NS-319. It is a direct-fit replacement for the listed applications and fits many vehicles, among them the 2004-2008 Chevrolet Silverado 1500 and 2004-2008 GMC Sierra 1500. See the "Vehicles it fits" section for the full list and engine details.
The neutral safety switch reports gear-selector position to the starting circuit, so the engine is allowed to crank only when the transmission is in a safe position. If a worn or failed switch is the cause of a no-crank or intermittent-start condition, this unit replaces it.
- Original equipment ignition know-how: Standard Ignition is a global manufacturer of original equipment ignition products and maintains quality control across the entire manufacturing process, from componentry to finished product.
- Copper alloy conductors: Provide superior electrical conductivity with low resistive losses.
- 100% tested: Every switch is checked to verify both mechanical and electrical switching performance.
- Built for technicians: Robust design and high-grade materials, backed by decades of research and development focused on what technicians need.
Signs this part may need replacing: the engine won't crank in Park but cranks in Neutral (or the reverse), intermittent no-crank conditions, or cranking only after moving the shifter. Other starting-circuit faults can cause the same symptoms, so diagnose the cause before replacing.

Frequently Asked Questions
What does a neutral safety switch do?
It signals gear position to the starting circuit so the starter can engage only when the transmission is in Park or Neutral. This helps prevent the engine from cranking while in gear.
What are signs the neutral safety switch may need replacing?
Signs may include no crank in Park but a crank in Neutral, intermittent no-crank conditions, or cranking only after moving the shifter. Other starting-circuit faults cause these too, so diagnose first.
Which vehicles does the NS-319 fit?
It fits many vehicles, including the 2004-2008 Chevrolet Silverado 1500 and 2004-2008 GMC Sierra 1500. See the "Vehicles it fits" section for the full list.
What part numbers does the NS-319 interchange with?
It interchanges with NS38029, DR4146, NS6811 and 24221125.
How is this switch tested?
Standard Ignition states its parts are 100% tested to verify both mechanical and electrical switching performance. The switch uses copper alloy conductors for strong conductivity with low resistive losses.
