ON-OFF-ONN 3 POSITION SWITCH FOR COIL SPLITS

[ehdwuld]

So i have several two hum guitars

I want a single switch to split both humbuckers

If it in thhe center position it does nothing

Either side and it splits to one screw coil and one slug coil on the pickups

This maintains hum cancelation when both are played together

And gives me a choice of which coil is active when played individually

Does anyone see any fault in this drawing that i do not?

Looks good

Assuming the terminals with the black are sent to the toggle or blade switch, yes, this works. I have an HS strat with a Cool Rails in the neck wired with a center-off switch like this. No audible difference in that alone, but the middle position on the toggle with the north/south coils yields some different tones.

I also have some HH guitars that use push/pulls to achieve some similar coil combinations. On one of them I physically rotated the neck pickup so that the screw coil is closer to the bridge. The result is that the split coils are in an inside/outside configuration and that yields a wider change in tone due to the increase in the coil separation.

The Strat that I use to try pickups has exactly this . I've wired it to ground a bit differently but the switch and its effects are the same...

I had a drawing where it went
parallel, series, split

I can't find it

And I like the slug in the neck better anyways

I think

Don't use parallel a lot is what I'm saying

i have series/split/parallel wiring on a few strats with buckers. i use on/on/on dpdt switches for one pup, or 4pdt on/on/on switches to do two pups at the same time

I'll just toss in that your red lines should represent both the red & white tied together. Not just the red wire.

Yes I assumed that was understood

The white doesnt show against the background

Ok so swapped the pickups

Everything went well
Lost a pickup mounting screw and when i returned fro. The store it was still hanging on the old pickup.

5 of the grub screws for the strings fell out.
found all but one

Nut fell off
Not really a nut with the zero fret
Just a string spacer
so its just letting the titebond dry

Everything worked fine

Got the neck and bridge reversed on thw switch

Moved the terminal connections
Now I done messed something up

The switch was 9mm tall and had 10mm of wood from the pickup cavity to the top

Had to dremel some wood out to get the threads of the switch exposed.

I will go back at it in the morning

And get more grub screws

Looks good. Switch wiring and guitar.

Here is a test

Swapped the ceramic magnets with A2 in neck and A5 in bridge

The alnico were smaller than the ceramic
And I think I got one shifted to the rails and one to the screws
