Standard Ignition NS-197 Neutral Safety Switch

Neutral Safety Switch for Nissan Applications

Standard Ignition NS-197 is a screw-in neutral safety switch built with a metal body, dichromate finish, and 12V electrical design. It uses two male blade terminals and a 2-inch wiring harness length for a direct replacement on select Nissan vehicles.

Compatible With Nissan 720, 200SX, 280ZX, 210, 510, and 810 applications, this NS-197 neutral safety switch supports proper starter circuit operation and transmission range signaling where the original switch has worn or failed.

Detailed Description

The Standard Ignition NS-197 is a replacement neutral safety switch engineered for select Nissan models, including the 1978-1981 Nissan 510, 1979-1982 Nissan 210, 1979-1983 Nissan 280ZX with indicator light, 1980 Nissan 810, 1980-1983 Nissan 200SX, and 1980-1985 Nissan 720. It is also listed for additional Nissan fitments within the same year range. The screw-in design, blade terminals, and compact metal housing make it a practical service part for restoring the electrical interlock function tied to the transmission range circuit.

This NS-197 cross-references Standard Ignition NS-197 and interchange numbers such as 32006K2400 and JA4237 for the same application.

What It Helps Resolve

• Engine starts only in certain gear positions
• No-crank condition related to the neutral safety circuit
• Intermittent starter engagement
• Faulty transmission range signal to the starting system
• Wear-related failure of the original switch contacts

Installation Notes and Tips

Install the switch in the original screw-in location and verify terminal orientation before connecting the harness. Because mounting hardware and gaskets are not included, reuse serviceable original components or source the correct sealing parts as needed. Confirm vehicle year, model, and transmission-related application details before installation, especially on Nissan 280ZX and Nissan 210 vehicles with indicator light notes.

Quality Assurance

Standard Ignition supplies electrical service parts for replacement use, and the NS-197 is built with a metal housing, dichromate finish, and OE-style terminal layout for consistent fitment on listed Nissan applications.
