    Nitrous Oxide Systems is proud to present our 2 Stage Wide Open Throttle/ RPM activated Window Switch with Shift Light Control. The WOT/RPM activated window switch is a small, compact, user friendly unit with features like, 2 fully programmable independent RPM window switches that can operate from 0 to 20,000 RPM for anything from a low rpm engine to a high revving sport bike. It has the capability to read a rising or falling throttle position sensor for accurate activations every time. The WOT/RPM activated window switch also features a programmable output to activate a shift light for on-time gear pounding shifts and a handy recall feature that shows max RPM and TPS voltage for easy set-up. Window switches have just been taken to the next level!
