Can I use a DPDT switch for a PU selector?

    Hello everyone!

    I've a question about the switch wiring. In fact I got a Fender PS51 (well, it's a hybrid but has a tele headstock), I really don't like the rotary switch on it so I decide to change it with a toggle switch.:idea:

    This is the diagram of the current wiring (It's a squier 51 version, but I think they are the same)

    I'd like just to change the selector part, keep all the thing else. An on-on-on mini toggle is ready (I'm not sure it's a DPDT or DP3T, but it has 6 terminals), also I drew a diagram for the switch like this:

    [​IMG]

    BUT someone told me, in my diagram, when the toggle is in the mid-position, none of the pickup works...:confused:

    I need your helps! Thank you vey much!

    Whoever told you that neither pole is active in the middle position is mistaken. That's the whole purpose of an on-on-on switch.

    6 solder lugs are correct for a DPDT switch. Each vertical column of 3 lugs in your diagram is for one pole. So that gives you two poles (the double pole part of DPDT).

    The top and bottom lugs are the throws, and the center one is the common, or the pole. Top and bottom gives you two throws (the double throw part of DPDT).

    If the switch is an on-on-on 3 position switch, and you follow the drawings you posted, the pickups will work properly. If it's a 2 position dpdt, or an on-off-on three position switch, you'll have problems.

    As above, needs to be On-On-On. Many DPDT are On-Off-On, which of course won't work.

    I did one with a mini toggle. Works fine.

    Should be fine, but a regular LP 3-way toggle is much smoother to use. You could also hack out a hole with drill and chisel (or router, if you're anal) and mount a 90 degree LP toggle in the upper horn, like I did on my $99 Squier '51 :D

    and put a tone control in the control plate where the rotary switch was:

    Thank you for your nice explanation, it's clear! Now I understand the meaning of these switches. :)

    Another reason that an on-off-on DPDT toggle wouldn't work (or if you find a two-position on-on DPDT toggle) is that these switches are not "make-before-break." Because they disconnect one connection before they make the new connection, there would be a popping sound as you flip the switch if you use it for a pickup selector - which is why that big honking Switchcraft toggle switch became popular (it's make-before-break, with the middle position on). Now if you're using a DPDT on-on-on switch with the special middle position it will probably not have any popping issues since it's more or less a make-before-break switch (and be careful, it's not standard by any means, most DPDT's are going to be two-position on-on or on-off-on if they have three positions).

    Also on the make-before-break theme - take a good look at a vintage three-position strat switch. The wiper is wide enough to contact two pickups at once as you sweep from one position to the next. I'm pretty sure the guitar gods of the sixties noticed this...;)
