The RPM switch output can be set up to operate in 3 different ways:

  1. On RPM setting below Off RPM setting, such as On at 3000 RPM and Off at 6000 RPM - this will operate like a window switch. The output will be on whenever the RPM is greater than 3000 RPM and less than 6000 RPM. This may be useful for nitrous control, for example.
  2. On RPM setting set the same as Off setting, such as On and Off both at 6000 RPM - this will operate like an on/off switch. Switch will be on above 6000 RPM and off below 6000 RPM.
  3. On RPM setting above the Off RPM setting, such as On at 6000 RPM and Off at 5000 RPM - this will operate like a latching switch. After the output activates at 6000 RPM, it will stay on until RPM drops below 5000 RPM. This may be useful for applications where you want the output to stay on until a gear shift has been completed, for example.
