Turbo Action Neutral Safety Switch

Turbo Action Neutral Safety Switches: Race-Proven Protection for Your Transmission Build

When you invest in a high-performance Turbo Action drivetrain setup, every component in the system needs to perform at the same level — including the neutral safety switch. Turbo Action's neutral/reverse safety switches are purpose-built to complement their legendary Cheetah SCS shifter lineup, giving builders and racers a cohesive, fully integrated transmission control solution from a single trusted source.

What a Neutral Safety Switch Does — and Why It Matters

A neutral safety switch is one of the most critical electrical safety components in any automatic transmission vehicle. It is a device found in vehicles equipped with automatic transmissions, and its primary function is to prevent the engine from starting unless the transmission is in either the "Park" or "Neutral" position. They will only allow your car to start when it is in park or neutral — not while it is in gear — because if a vehicle starts in gear, the damage that could be done is significant. Beyond basic engine protection, these switches can also be used to turn on backup lights when your car is in reverse , making them doubly functional in street-driven builds.

Turbo Action's Approach: Integrated Shifter Compatibility

Turbo Action introduced the first-ever competition TH-350 transmission back in 1970, and since then has continued to develop cutting-edge products like its Cheetah valve body. Their landmark products include the Cheetah valve body, Powerglide Tranz Brake, and Cheetah SCS shifter — and their neutral safety switches are engineered specifically to work seamlessly with these systems. The Turbo Action neutral/reverse safety switch (part 70210A) is designed as a direct-fit solution for the Cheetah SCS shifter platform, ensuring that the electrical safety circuit integrates cleanly with Turbo Action's race-oriented hardware without improvised wiring or adapter headaches.

Turbo Action manufactures racing applications for the automotive market, with a product range that includes shifters, transmissions, torque converters, and valve body kits for street rods, hot rods, sport trucks, speed boats, and street performance cars. This broad ecosystem means the neutral safety switch isn't an afterthought — it's a carefully considered part of a larger, race-proven system.

What to Know Before You Buy

When selecting a neutral safety switch, first confirm the transmission type as well as the shifter being used to ensure compatibility. Turbo Action's switch is matched specifically to their Cheetah SCS shifter hardware, so it is the natural choice for anyone already running — or planning to run — that platform. Whether you are building a dedicated drag car, a street/strip machine, or a performance hot rod, pairing the correct neutral safety switch with your Turbo Action shifter ensures both safety and electrical reliability under demanding conditions.
