RPM Activated Window Switch
Activate and deactivate circuits, RPM modules used to activate the switch

The RPM Window Switch has two rpm adjustments; one to activate a circuit, while the other deactivates the same circuit. This switch will supply then remove ground to a circuit. This is a great feature to deactivate nitrous before the engine's rev limit is reached. The switch can be used with stock inductive ignitions or an MSD Ignition and can handle up to 1.5 amps. No rpm modules are supplied so they must be ordered separately.
