Activate and deactivate circuits at pre-programmed rpm "windows" with these MSD switches. They are especially useful for nitrous equipped engines, because the nitrous system can be shut down just before the engine's high rev limit. They include a ground to activate a circuit, and can handle up to 1.5 amps.
