    Hey guys, i`m brand new to the forum, i`m hoping someone can clear something up for me

    I bought a center off DPDT switch to switch from neck pickup to bridge since i never use both at the same time.

    Unfortunately I cannot seem to get the thing to work!

    I have the +/- connected to the middle (pin 2 and 5)

    testing with two speakers, i can only get sound into one speaker into one position.

    since this is supposed to be an on-off-on two way toggle switch, should not the sound change from one speaker to another when i throw the switch?

    Well, it certainly does not. any help would be appreciated, and I can provide more info just in case i`m not being clear enough! how frustrating!

    I cant help but notice the switch says AC on, am i to assume I need DC since I believe speakers and pickups run DC current?

    Since I don't know exactly how the pickups work and you didn't provide a schematic, I can only make an educated guess:
    I assume there are two wires from each pickup.
    And there are two wires going to the amplifier.
    So the connection should be:
    - wires from neck pickup to the two left outer contacts of the switch.
    - wires from bridge pickup to the two right outer contacts of the switch.
    - wires from the two center contatcs of the switch to amplifier.

    By the way:
    - in center position there will be no pickup connected at all ("center off" switch).
    - Your wires most probably are shielded. Don't forget to connect all shields (optimum: put switch and wires in a metal box, connect the box to shield, too) to minimize noise and distortions.

    That is where i`m stuck.
    The switch doesnt have a dent in the middle so it`s truly an on-none-on switch.

    This is my layout without having a schematic (at work atm)

    -Each pickup is 2 wire- so they`re connected to each end of the outer terminal

    -the center 2 are the +/- from the volume pot pin 1/ground

    -the tip input is on pin 2 of the volume pot and the neg is ground

    When I bypass the dpdt with clips i get signal on both pickups, all parts appear to be working independently.

    for some reason though, i can throw the switch one way and get signal, but it never seems to work in the other direction.

    When I get home i`ll post some photos and or schematics!

    ok see if this helps in the wiring process :)


    note how the direction of the switch lever is in the opposite direction to the set of contacts selected.
    The switch I have shown is a DPDT ON-ON ... ie. no centre off
    I would assume you dont reallly need a centre off as you have hinted at that you are using
    Regardless it would affect the way the pickups are wired to the switch
