NOTE: Not for use with ZEX control box's

This 2 channel RPM activated window switch (RPMWS) also has an integrated throttle-position activation switch (TPAS)! The unit accepts most tach signals, including low-voltage and irregular signals such as those found on many V-10s. The TPAS accepts all analog throttle-position sensor signals as well as a “hot” or “grounded” wide-open-throttle (WOT) switch.

It also has a feature called "Multi-Gear Lockout". This feature will allow you to drive off the line in first and not spray until second gear! You can actually select what gear you want the nitrous to start spraying! Amazing time reductions have been made with this feature.

Both channels have their own settable ON and OFF points, and each has its own multi-gear lockout feature, which allows it to be turned off until you have cycled through the window. The internal TPAS can be configured to prevent the RPMWS channels from activating unless you are at WOT.

The RPM WINDOW SWITCH requires 9~18 volts to operate correctly. The output lines switch ground when activated (ON) and have a maximum current rating of 1 amp. All this and only the size of a spark plug box.

The RPM WINDOW SWITCH is built for the racing environment to withstand heat, vibration, dirt and water. It is designed to operate over the temperature range from -40 to +185 degrees Fahrenheit (-40 to +85 degrees Celsius).

Features:
* 2 independent channels
* Integrated wide-open-throttle detection
* Each channel has a multi-gear lock-out setting
* User configurable for rising or falling TPS signal
* Supports low voltage tach signals as low as 3 volts
* Works with irregular tach signals such as V10 and 3cyl
* Push-button programming with integrated LED digital display
* Compact rugged, waterproof design

Benefits:
* Built for the racing environment to withstand heat, vibration, dirt and water

ATTENTION: Some cars with dirct fire coils may need to use a tach adaptor. Seems like most EFI mustangs and direct col GM cars/trucks need a tach adapter to clean up the tach signal. See our Tach Adapter for sale in this same section! 

NOTE: An additional relay may be needed on some installations.

The Rpm window switch is a great additon to any nitrous kit.
