  • Rotary pickup selector switch

    Hello,
    I am trying to wire a rotary pickup selector switch to control two humbuckers. Upon looking at a Framus diagram I cannot tell if the switch is 2 pole or not. Is there a way to tell the difference . All of the books I have looked at only show a primary circuit.
    Anyway I hope some one knows how to do this. Didn't some harmony guitars use that method?
    Thanks for any help in advance!

    From what I can tell here:

    Alexplorer's Axe Hacks: Rotary Switching Possbilities.\

    it looks like this switching is usually done with a 4 pole 5 or 6 way switch (if the combinations shown are what you are expecting). That would mean the rotary switch has two wafers, each wafer having 2 poles.

      I've done some mods with both 2- and 3- pole rotary switches. At the most basic, since there are no 'in between' positions on a rotary switch, if you want to combine pickups in parallel, you must wire one pickup to one pole, and the second pickup to the other pole, something like:

      Neck Neck N/A
      N/A Bridge Bridge

      so three positions and two pickups, like a standard 3-position toggle. Get creative and add tone controls and coil taps on additional switch poles!

        Hello,
        Thanks guys, I know about the 4 pole 5 position rotary switches. I used one to split a pickup on a Les Paul JR. copy I made out of parts. Out of phase, parallel,north, south coil, and normal. I was just looking to clean up another project by dumping the toggle switch. I always thought it looked added on as an afterthought.
        I found a rotary switch which replaces the toggle switch on a Framus diagram. Both poles of the drawing had the same orientation, when I realized that I got it worked out and functional.
        Thank you for your input, It's nice to know there is a place to ask questions when your at a loss!!!
