Eb2 is right about the hardware store. The switch I pulled from my EB2 was made by Leviton (happy Mark?
). Looks like a pushbutton lamp switch.
I found
this one thru Amazon:
Not sure if dimensions on that switch are correct, as they do not provide them. The shaft on my switch was 3/8" (despite the fact that the hole it mounts in was 1/2").
The reason mine is pulled out, BTW, is because using the "choke-mod" works a lot better by giving the bass three distinct sounds - the third one being the sound of the pickup without any residual filtering from the choke circuit. You would especially appreciate that full-range sound with more midrange punch in live/band settings. You can use a pickup selector toggle for a 3-pickup Les Paul for this mod (with one minor modification - to the switch, not the guitar) to accomplish this. I can provide details, pics, and schematics if you decide to go the non-original route.
