Two Step Rev Control For Digital 6AL MSD8732 Engineered exclusively for use with the Digital 6AL ignition, two-step unit allows chang- ing starting line limit RPM right from the driver's seat. Easy-to-read rotary dials allows setting RPM limits in 100 RPM increments. Activation wire
Used for many functions, from turn- ing on a bulb or solenoid to starting a timing computer. Switch has two wires, one ground and one to open a circuit. Plug in an RPM module and wire the switch to the circuit. Once the engine
connects to the transbrake, clutch switch or line lock to activate the low RPM limit. Once the switch is released, the low RPM limit is deactivated as the car launches.

reaches the selected RPM, the circuit is active until RPM drops below that point. Window switch includes two RPM circuits, one to start and one to discontinue and is ideal for nitrous applications where the system must be shut down before RPM limit is reached. Compatible with stock inductive or MSD ignitions. RPM modules not included. Part No. Description MSD8950 RPM Switch MSD8956 RPM Window Switch Digital RPM Window Switch MSD8969 Switch turns circuits on and off at specific RPM intervals. Accepts an RPM input signal from a negative coil terminal or a tach output from an ignition control or an ECU. Switch has 200 to 15,000 RPM capability.
