A simple way to create dual(or more!) rotary switches out of single rotary switches

[Variac]

Well, the clever insight here IMHO is the reminder that a typical switch or pot doesn't have to turn 360 (or 720) degrees, but probably only 270.

Another way to do it would be to make little arms out of maybe 6 mm aluminum about 40mm long say, with a 6mm hole on each end and a setscrew for each hole. Then you could put the arm on the front pot shaft, and clamp it, then clamp a shaft in the other hole extending back to the next pot, add a second arm between this shaft and the second pot shaft.
This way would be shorter, cleaner, and could connect quite a few pots. Should be a standard item!!

Do I need to draw a picture?

Hmm, maybe you should have a drink before doing stuff like that next time

Its not really a problem with chips getting stuck inside the switch, compressed air will deal with that.

This is not simple, but very elegant way:

Roberto needs to post some more of his creations here!

Check out his avatar... very interesting

He does some amazing work.

you can make it simpler by not using the cogwheels but a central rubber wheel (style of which you find in the K7 player systems and have it press tightly against(and situated between both shafts of which one has the knob attached to it.
