The MSD RPM Module Kits and RPM Module Selectors give you a full selection of RPM values to choose from. The individual modules and Modules Selectors plug into MSD MC-3 Ignitions, Shift Lights and RPM Activated Switches.
MSD Smart Switch (PN 8966)
This is truly a Smart Switch! Not only can you choose between supplying ground or 12 volts to activate a circuit, but you can do it through the use of a long list of vehicles sensors! As long as the sensor is within 0-5 volts DC with a minimum signal difference of 0.5 volt, such as TPS, MAP, MAF, water temperature, oil pressure, boost pressure, etc…the Smart Switch can be used!
The switch can be calibrated to ‘learn’ the sensor and it can be programmed to activate at a certain percentage of the sensor’s signal range. Use it to activate a nitrous solenoid when the TPS sensor reaches 95% or when the coolant temp sensor reaches a certain level to turn on an electric fan.
Activate a device from 0-100% of a sensor’s voltage output signal.
Connects to a wide range of sensors such as a TPS, MAP, MAF, temperature (oil or water), nitrous or boost pressure.
Built-in LEDs assist in calibration and switch activation points.
Activate a circuit by supplying a ground or a 12 volt source.
Dual Time Delay Relay (PN 7563)
Do you need to activate a timing retard for a split second or activate a nitrous solenoid 0.8-seconds into a run? Our new Dual Time Delay Switch can accomplish both of these tasks!
The Dual Time Delay Switch allows you to provide a ground, or remove a ground to a circuit or control relay to two different circuits. The Switch can easily be programmed in 0.01- second increments using the touch screen and the LED readout.
Activate two different circuits based on time such as a boost or nitrous controller.
Digital read out and buttons for easy programming.
Provide a ground or remove the ground for circuit activation.
Program the time activation down to 0.01 second increments.
MSD Module Selectors
Instead of carrying around a handfull of your favorite RPM Modules, why not use an MSD Module selector? It plugs right in where the RPM Modules go. You have a choice of 12 rpm points by rotating the knob that has positive stops for each rpm point. There are 6 different models, and each model has 12 different selectable rpm points in 200 RPM increments.

Digital RPM Window Switch (PN 8969)
This advanced RPM Window Switch will activate a circuit at your desired rpm, then turn it off at another rpm! This Switch will accept an input rpm signal from a coil negative terminal (for stock ignitions), a tach output from an ignition control, an ECU tach output or even a 5 volt tach signal. Another great feature is that no rpm modules are needed! The rpm activation points are programmed by simply scrolling through the LED display to your desired rpm amounts.
The switch has two outputs; one Normally Open, the other is Normally Closed. It can be programmed from 200 rpm to 15,000 rpm in 100 rpm increments. It can be used with an input voltage of 9-18 volts.
