Accurately Control Nitrous Activation
The NOS 2-Stage RPM Window Switch has two completely independent rpm adjustments. Each can be used to activate and deactivate a nitrous kit at wide open throttle only (using the built-in TPS activation), as well as within a predetermined RPM window. This allows for maximum safety and tunability. This way you can combine the functionality of a WOT switch and the ability to control what RPM each stage kicks in.

Built-In Shift Light Output
Besides the NOS 2-Stage RPM Window Switch's many built in nitrous activation and deactivation features, there is also a programmable output for a shift light. This switch has so many built-in features it may replace several other individual components in your setup, simplifying usage.

Wide Range of Fitment and Adjustment
This NOS RPM window switch can be used with nearly all ignition system types on any 4-stroke engine from 1 to 12 cylinders. Activation/deactivation points can be set from 0 to 20,000 RPM. Each output can also be used to activate other electronic accessories, not just nitrous. Shift light output is easily programmed from 0-9,999 RPM. The TPS activation is not required to be used for the window switch function to work, so you can also use this for carbureted applications as well.
