A question regarding the rotary switches - can you limit them physically to a certain number of positions, or is is a constant rotation 12 position switch?

They look very similar to the C&K ones that I have, which have an indexable stop. It' a washer with a tooth that you insert in the appropriate hole

I just finished my little project, and these selectors saved it.

With 6x 12-pos selectors, it would have been 72 inputs and 78 wires, to be added to 5 encoders, 7 axis, and a bunch of levers and buttons.

Now I'm thinking, this could be used for 3-pos ON-ON-ON switches as well, with the 1k resistors.

Without knowing exactly how the code works, it might give odd results, or not work at all, with just 3 or 4 resistors.
You might have to add extra resistance at one end to fool the processor and make the 3 positions the first or last 3 of 12.
It could be worth experimenting.

Or you could use four ON-ON-ON switches wired in series with the resistors?

That wouldn't give four independent outputs, though.
As I understand it, each of those switches can only select between one of 12 outputs.

I think on the three first positions the board just sees 1kOhm, 2kOhm, 3kOhms
