I am midi-fying an old pedalboard of unknow manufacture. the toe pistons have 3 contacts that touch a copper plate in sequence as the piston is pressed. The middle contact touches first, then the left contact, then the right contact. Once a contact touches, it stays connected, so when the piston is fully pressed all three make contact, When the piston is not pressed, no contacts touch. (sorry, can't figure out how to post images)
I am thinking the middle contact is power or ground and the other two are the signal. Is this correct? Is this some kind of debounce method? I can't think of any kind of simple flip/flop setup that would work, since this isn't a double throw.
Thanks in advance
