    I recently assembled my dream partscaster. It has two Duncan humbuckers, both 4 conductor. I set it up with a 3 way blade switch, a master tone, a master volume, and a 2 way toggle for cool splitting the pickups (one position for full buckers, one position for split singles). I am a caveman, so I brought it to my local tech for wiring.

    He told me that it's not possible to split both pickups with one 2 way toggle, and that it will need a 3 way toggle or a second 2 way toggle.

    I've had several guitars that are dual humbuckers split by one push/pull tone knob, so it seems one toggle switch should be able to split both humbuckers, right? Am I on the wrong path? Again, I admittedly know nothing about wiring/electronics.

    He's wrong. You can easily do it with a single mini-toggle switch (or a push/pull switched pot). As long as the switch is dpdt (which will have 6 lugs). That's a very common switch.

    If you're a caveman, then your tech is a gorilla. Maybe a lungfish.

    Here is a schematic to print and take with you, from Phostenix's site. Drawn here with a push/pull pot but this could be a toggle switch (but notice how this switch is designed with basically two single toggles attached side-by-side with one lever). You could wire it up so the outside coils are selected instead of the inner or any combination.

    Simon, a spdt (or really just a spst) will split ONE pickup. But the OP wants to be able to split BOTH pickups simultaneously with a single switch. He needs a dpdt.

    @JohnnyShoulders , you said you want to have master vol/master tone. Do you want to use the empty position for the 3rd pot for the toggle switch?

    Anyway, this is the diagram you need. I have no idea why it says "2 push/pulls" there is only one. If you prefer a separate toggle switch instead of a push/pull, it should be wired and will work the same. NOTE that this diagram is specific to the Duncan color codes. It is wired to have the split neck/bridge position also be a noise-canceling pair. That's cool but not necessary. What pickups have you got, by the way?

    One DPDT switch can split 2 pickups (one each side). I actually use a Fender S1 switch to do this on my HH Music Man.

    Do you mean the diagram that the OP has in post #1?

    It does work. It's a clever way to send the THREE split wires to ground using a dpdt push/pull switch (because that's the only kind they make!) without jumpering any of them together. It uses one side of the 5-way switch to select which split wire (neck or bridge) to send to one side of the dpdt toggle.

    Yes, that was it Fumbler. Thank you for explaining it, because I just couldn't see it. I hope I haven't confused the OP too much. (Message to self: don't be too quick to help others when you have an IT problem of your own to resolve...)

    So it turns out I had an SPDT switch instead of s DPDT switch, so it was my bonehead mistake. I'm going to get a DPDT switch and I should be able to do what I want. Thanks for all the help, guys!
