Standard Ignition NS-79 Clutch Starter Safety Switch

Clutch Starter Safety Switch for GM Applications

Standard Ignition NS-79 is a clutch starter safety switch built for vehicles that require the clutch pedal to be engaged before the starter circuit is allowed to operate. It uses a female connector, a single connector interface, and male blade terminals for a direct electrical connection in the starting circuit.

Compatible With 1991-1993 Chevrolet Lumina, 1988-1993 Pontiac Grand Prix, 1988-1992 Oldsmobile Cutlass Supreme, and 1989 Pontiac 6000. This part number, NS-79, is also a direct reference point for service lookups on these applications.

Key Features

• Clutch starter safety switch for manual-transmission starting circuit control
• Female connector with 1 connector interface
• 2 male blade terminals for straightforward electrical connection
• Copper alloy conductors for strong electrical conductivity and reduced resistance
• 100% tested for mechanical switching and electrical switching performance
• Robust construction using high-grade materials for service use

Detailed Description

Standard Ignition NS-79 is engineered for dependable starter interlock operation in select Chevrolet, Pontiac, and Oldsmobile vehicles. The switch is built with copper alloy conductors to support efficient current flow, while the blade-terminal design helps maintain a secure connection in the clutch-start circuit. For technicians servicing a Chevrolet Lumina, Pontiac Grand Prix, Oldsmobile Cutlass Supreme, or Pontiac 6000, NS-79 provides a direct replacement option for the original clutch starter safety switch.

This part cross-references Standard Motor Products (e.g., NS77, NS6440) for the same application.

Common Issues This Part Can Address

• Engine will not crank when the clutch pedal is pressed
• Starter engages only intermittently
• No-start condition caused by a failed clutch interlock switch
• Starter circuit interruption from worn internal switch contacts
• Electrical connection problems at the clutch pedal switch

Installation Notes and Tips

Verify connector style, terminal layout, and vehicle application before installation. Inspect the clutch pedal linkage and surrounding wiring for wear, corrosion, or looseness that could affect switch operation. After installation, confirm that the starter engages only when the clutch pedal is fully depressed.

Quality Assurance

Standard Ignition states that this switch is fully tested for both mechanical action and electrical switching performance. The design also reflects long-term product development focused on technician service needs.
