Kiwi Posted November 8, 2009 Share Posted November 8, 2009 Is there any way to wire a pair of ON/ON/ON 3TDP switches and humbuckers so I can select inside coils, outside coils and have both coils in each pickup running in parallel? If it uses a DPDT switch instead of one 3TDP then so much the better. I've spend most of today trying to get my head around it and failed. Mainly because I can't work out how the 3TDP switch makes its connections. Basically I'm hoping its possible to take this option: and change the humbucker wiring shown to parallel instead somehow. There has to be more than one way to do it though, I have potentially two switches to play with. Not that fussed about series mode to be honest. Doesn't do a lot compared to parallel and the voltage difference is irritating. Quote Link to comment Share on other sites More sharing options...
Higgie Posted November 8, 2009 Share Posted November 8, 2009 (edited) A 3PDT switch is exactly the same as a DPDT, just with an extra switch in it. With a DPDT you have 2 switches and 2 things to switch between (ie on/off). A 3PDT has 3 poles, but 2 things to switch between. That's why they are used for true bypass in pedals, as it allows you to connect the input to either the output (true bypass) or the effect and the extra switch in it can turn an LED on and off. True Bypass can be achieved without a 3PDT, you just wouldn't be able to use an LED without some clever jiggery-pokery. Not very specific to your question, but I hope that helps you understand the workings of a 3PDT. Edit: Just read a little closer and saw you said 3TDP. Whoops! I guess this post could be helpful to some though so I'll leave it here... Edited November 8, 2009 by Higgie Quote Link to comment Share on other sites More sharing options...

Bottle Posted November 9, 2009 Share Posted November 9, 2009 (edited) OK CK. I've worked out how to do it with a pair of on/on/on toggles (one per humbucker) - I'm just transferring it to paper/pdf. Watch this space! HTH. Ian EDIT: Here you go!! Try this - watch out for the phase on each coil. [attachment=36035:CK_Humbuckers.pdf] PM or post if you need a diagram for series/single/parallel wiring per humbucker (again using on/on/on toggles) Edited November 9, 2009 by Bottle Quote Link to comment Share on other sites More sharing options...
Kiwi Posted November 9, 2009 Author Share Posted November 9, 2009 Thanks for that Ian! Which of those connections are north-start, north-finish, south-start, south-finish? [i]Bridge HB toggle[/i] 5 = south-finish 2 = north-start earthed = south start and north finish? [i]Neck HB toggle[/i] 5 = south-start 2 = north-finish earthed = south finish and north start?

[i]Neck HB toggle[/i] 5 = south-start 2 = north-finish earthed = south finish and north start?[/quote] Hey Kiwi I'd use the Bridge HB wiring for both pickups TBH - the diagram you've posted at the top seems to be the easiest wiring to follow: [i]Bridge HB toggle[/i] [b]2[/b] = south-finish [b]5[/b] = north-start earthed = south start and north finish That should work and avoid any messed up wiring / phase issues when running both the Bridge and Neck p'ups through a VVT or VBT stack. Let us know how that works out Cheers, Ian Edited November 10, 2009 by Bottle Quote Link to comment Share on other sites More sharing options...

Bottle Posted November 10, 2009 Share Posted November 10, 2009 Cool! Glad to be of service, and good luck with the wiring Quote Link to comment Share on other sites More sharing options...
