Hi Lucky
Are you sure you have got the original Nord Half Moon Switch :

https://www.sweetwater.com/store/search.php?s=HalfmoonThe last one are not compatible with your Nord, the internal wiring are different.
I know because I have both, and tried to use the last one on a Neo Ventilator, but could not get it to work, or rewire it to work. What works on a Nord will also work on a Ventilator.
If you want to check the function in your board, you can plug in your normal sustain pedal in the Rotor Pedal inlet.
The only thing it will do, are toggling between slow and fast when you have the Leslie/Rotary enabled.
