Detailed Product Information

Standard Ignition NS724 is a clutch starter safety switch for vehicles equipped with a manual-transmission starter interlock. It helps ensure the starter circuit only engages when the clutch pedal is in the correct position, supporting safe and consistent starting performance. This part is a practical OE-style replacement for select 2011-2017 Buick Regal, 2015-2019 Chevrolet Colorado, and 2015-2019 Chevrolet Sonic applications. This part cross-references 1S12695 and CSW621 for the same application.

Common Problems This Part Can Help Solve

• Starter will not engage unless the clutch pedal is positioned correctly
• Intermittent no-crank condition caused by a worn safety switch
• Starting circuit issues related to poor terminal contact
• Replacement need after switch wear, contamination, or electrical failure
• Restoring clutch interlock operation on manual-transmission vehicles

Installation Notes and Tips

Verify terminal style, connector fit, and vehicle application before installation. The NS724 uses a male, 3-terminal blade configuration, so matching the connector and switch orientation is important for proper installation. Confirm the clutch pedal switch location and test starter interlock operation after installation on your Chevrolet Colorado, Chevrolet Sonic, or Buick Regal.
