Amazon.com: DiMarzio Three Position On/On/On 4PDT Pickup Selector Switch: Musical Instruments

I need to get one of these in my possession. I assumed that they would switch like 2 DPDT On/On/On switches side-by-side, but then I saw this on another forum:





If the DiMarzio 4PDT 3-way switch works like this, I need to make a couple of changes to my drawing above.

Yes, it does. It's like two on-on-on switches next to each other.

Yes, it does. It's like two on-on-on switches next to each other.

If that's how it switches, then it's NOT like two On-On-On switches next to each other. That switching diagram has 2 switches that are mirror images of each other. I drew my drawing for a switch that has 2 DPDT On-On-On switches next to each other, not mirrored like that.

There are (at least) two different kinds of "on-on-on". The one shown in the picture is what I think of as a "progressive" switch.

The other, more common kind just behaves like a regular "on-on" double throw switch, but has an extra middle position with all of the contacts closed. The Gibson pickup selector is a single-pole example of this kind.

It doesn't help that we're an international forum and every country has its own scheme for naming switches. In Germany it would be a "2x UR" or something.

The type of switch like a standard LP that interrupts one switch pole when the toggle is moved from the center position is not what I'm trying to understand here. I'm trying to determine if the DiMarzio 4PDT On-On-On switch, which seems to be the most readily available full size switch for these LP switching setups, switches like two DPDT On-On-On switches side-by-side or if it switches like two DPDT On-On-On switches mirrored (like the above switch diagram does). I guess I'll buy one and find out. I've got an old LP copy that I can use it in.

C&K's data sheet of their switches (which look like the DiMarzio switch) shows the 4PDT On-On-On switching like two DPDT switches side-by-side - not mirrored. You can get a C&K switch configured like the DiMarzio, but I've never seen anyone stocking that part number. My guess is that DiMarzio orders the switches from them. I don't know what the minimum order is from C&K, but I'm guessing it's higher than would make sense for someone like me to order.

Off to ebay to buy a DiMarzio switch....

DiMarzio 4PDT On-On-On 3-Way Toggle Switch Pinout

OK, I got the DiMarzio switch and have confirmed that it switches like two DPDT On-On-On toggles side-by-side, so my drawing above will work with the DiMarzio switch.

Looking through Darren Riley's inventory today and came across another 4PDT On-On-On toggle for less money than the DiMarzio.

Well, after the visit to the luthier that usually does my setups (and does pretty mean instruments himself), we encountered a few problems - namely, he doesn't have an extra long drill large-bore bit we'd need to drill the hole from the pickup cavity to the electronics cavity, and there's no way to drill a new hole from the switch cavity to the electronics cavity either because of the same problem.

Another problem that I discovered after resigning myself to wiring it in a standard manner (3-V-T, always in parallel) was the fact the pickup had only a single conductor and a shield, so S/P wouldn't work without injecting massive amounts of hum into the whole thing, unless I mod the pickup...

Thanks for this wiring, though, as it's still something that works, and someone else might be able to use it. My luthier did suggest another odd idea that I might just use: dropping a four-way Telecaster switch into the switch cavity and wiring it for series/neck/parallel/bridge operations. I'm not above giving an Epiphone a Fender feature - I side with the Schwabian school of "un-vintage".
