This is an idea that presented itself whilst I was working on my Esquire project. I’ve never been a fan of the tone switching options on the Esquire and wanted to do something a little different with the 3-way switch.
I did consider using it to select different sized capacitors to change the depth of the tone pot. I had to give this up when I realised I could fit the control plate back on as the cavity isn’t deep enough for the caps I used!
So it was back to the drawing board.
I’m building the Esquire using a GFS Lil’ Puncher (Barden style) bladed pickup and it has 4 conductor cables, plus a ground.
I’m using a genuine Fender 3-way switch (#51992-0441) and I realised that it should be possible to use it to switch the coils; after all it is a 2p3t (double pole, triple throw) switch.
I’m in the stages of wiring the guitar, so at the moment this schematic is at the “theoretically correct” stage.
Here’s how I would wire the switch. I’ve colour coded the switch lugs to make it less messy. I’ve also left out including a tone control, although this is easily done as in most standard schematics.
Here’s what you do:
Wire up the White and Red cables to the switch as shown above
Wire a cable to Lug 1 on the “B” side of the switch
Connect the wire you soldered in Step 2 and the “Black” cable from the pickup to Lug 3 of the Volume Pot
Connect a wire from Lug 3 on side “B” to Lug 3 on side “A”
Connect the Lugs colour-coded Black on the switch to Ground
Kudos, you've wired the Fender 3-way (a 2 pole 3 throw) switch into a DPDT ON-ON-ON (really a three position switch that we-all here never could agree to a proper name for) normally used for exactly this scheme.
I do appreciate your sharing your thought process and solution development in your post. It's a "fishing guide" of use to many.
I've an on-line co-worker in Horsham named Christopher Hobson, but I'm sure that it's asynchronously unrelated. ;D

Thanks Now if only someone would invent a 3way superswitch I could use different caps for the tone control - and then use dual 250k/500k pot for Volume (i.e. series to 500k and split/parallel to the 250k).
This is getting seriosuly addictive!
I also screened all the cavities in the manner of "Taming the beast's cousin" - it's really quiet, even in the split position. I tested it using my Marshall VS100 which is quite a noisy amp and there I couldn't detect a jump in hum levels until I cranked the gain on the OD2 channel and sat in front of my laptop.
