The Digital RPM Window Switch turns a circuit on at one RPM and off at another, accepting an input signal from a coil negative terminal, an ignition control's tach output, an ECU tach output, or a 5-volt tach signal. No RPM modules are needed — activation points are programmed by scrolling through the LED display. It has one Normally Open and one Normally Closed output, programmable from 200 to 15,000 RPM in 100 RPM increments.
