MSD RPM Activated Switches

Product images may differ from actual product appearance.

These RPM-Activated Switches will perform a variety of different functions from turning on a bulb or solenoid to activating an MSD Timing Control at a desired rpm. For 4, 6 or 8 cylinder engines, these Switches 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 seperately.
