RPM Activated Window Switch Take control of your nitrous system.
RPM activated window switch
Activate and deactivate circuits at pre-programmed rpm "windows" with this MSD switch. It's especially useful for nitrous equipped engines, because the nitrous system can be shut down just before the engine's high rev limit.
The window switch includes a ground to activate a circuit, and handles up to 1.5 amps. Revs adjust with the same plug-in modules used on other MSD rev controls, and is compatible with stock inductive ignition or hi-po capacitive discharge controls.
Sold individually.
