Coil split with a DPDT switch

According to this site, I should use a DPDT On-Off-On switch to split the rail pup in my project for it to work as follows:

 

Pos.1 - North Coil alone

Pos.2 (middle) - full on humbucker both coils

Pos.3 - South Coil alone

 

How would I wire up a DPDT switch for this? The diagrams there don't seem to be real clear. My idea is to have a coil split that allows (in position 2 and 4 of the 5-way strat switch) me to select which coil of the rail middle position pickup can be used with the neck or bridge pup respectively. The pickup is a 4 conductor GFS hot rail style.

 

Any ideas? need to know which wires from the pup go where and which on the switch go to ground and the 5 way.

I think he's mistaken. You'll need an on/on/on. The center position of an on/off/on is gonna be off now matter how you wire it. Also I don't think you're gonna see enough difference between the north & south to warrant doing this unless you got those SD pups that have the P90 & SC built into one pup. Can't remember their name. If you have these go to SD's site & check their wiring diags.

I agree with wartoxin on that. I believe for a normal application; ie. a typical 2 pup with a 3-way switch you would want the on-on-on but for this custom wiring you would want to go with the on-off-on for the way it is hardwired internally....

 

Awesome, but how do I do it? No one seems to show a good diagram with only a single humbucker and a 3 way switch.:idk:

This is the first one that I found:

It should get you in the right direction. I don't know what else you have wired in for controls and such. If you expand further I can possibly right you out a full one for you application.

Thanks soldier. I missed that link somehow in looking over the messages. That is exactly what I needed. I am wiring that up for coil split in the middle then jumping that off to make a mid + bridge series/parallel circuit mod as well. That gives me LOADS of options. Basic schematic for series/parallel here.

 

N coil mid only

humbucker mid only

S coil mid only

 

All the above with the bridge in series

All the above with the bridge in parallel

 

If anyone has a better idea let me know. I have a spare hole in the PG I was sent so any mod using a mini-toggle is cool.

Seymour has one under teles if you wish to use a blade type switch. It goes series/split/parallel. And IMO if you're going with a single humbucker & nothing else this will get you the most sound variety. You can use a dpdt on/on/on for that too.

OK here is the setup. I can't seem to make it work. SHS configuration. Humbucker is a rail type four conductor. I used this SSS schematic from seymour Duncan site. Instead of wiring the humbucker straight up, I used this diagram below to three way split the coils:

Instead of going from the "North coil" lug to the vol pot, I went to the location on the 5-way switch where the middle would normally be. Everything else is the same. I only get sound from the middle pickup in all positions. Looks to me like the split switch is bypassing the 5 way somehow. Any thoughts?

OH, FYI. I opted to do the North/humbucker/south coil split and then a simple kill switch for now, but I will add the kill switch once I have the pups wired right.

 

My main issue is the coil split to the DPDT On/Off/On that is shown above. Any definite way to identify the individual start and Finish for each coil? I grabbed a color coded schematic that appears to match but the rail pup is not very well identified...
