Hi y'all, Been a longtime since I was on here-Hope you are all well. I have made the cardinal sin of buying guitars faster than I can mod them, hence I have been quiet for a few years, plus I now have two kids :-) I recently came across a 2P4T slider switch which maybe some of you do not know about? I picked up a few on Ebay as I figured I could use one of these instead of two 2PDTs for series, pole coil, stud coil and parallel for humbucker switching. How does the below look? I think I have at least one hanging hot, but otherwise? Cheers, Danny

The diagram looks OK, if the switch logic is as shown on the diagram. Have you checked the manufacturer's data sheet on this switch, or tested it? If it operates in the manner you have shown, I will be quite surprised, as I've never seen a slide switch that worked that way.

Hi Newey! Good to hear from you after so long. You are of course quite right, it should be like this: Better? D

Are the same size as your standard dpdt slide switch? If so it would e great to control two pups with one switch.

Hi,
The holes for mounting with screws are slightly further apart than those for DPDT or DP3T. They also have pcb mount lugs and not the fatter ones with a hole for easier soldering.

It still doesn't look like any slide switch I've seen. So, if you have such a switch already, test it. If you haven't ordered it yet, check the data sheet.

Hi Danny.
I agree with newey. I strongly suggest you get out your ohmmeter and verify the connectivity of the switch in all four positions. The three and four position slide switches I've seen don't have "poles" per se. Adjacent lugs are connected together in the various positions.
Using your second drawing as a reference, what I would expect your switch to do is:
When slid to the top, lug 3 and lug 4 are connected together. Next position, lug 3 and the gray lug are connected together. Next position, the gray lug and lug 2 are connected together. Bottom position, lug 2 and lug 1 are connected together.

Makes sense how it works for a slide switch. Very similar to a 4 position blade switch I guess, with respects to switch logic. It is smaller than a standard dpdt slider.

Yeah, that is an odd one for sure. Tough to wire to those PCB pins, though.

Ackshully.......
What newey doesn't know, and I suspect the great majority of you all here/reading this, is that the terminals on this switch are perfect for use with a now-out-of-favor wiring technology known as "wire wrap". A w/w gun and a small diameter wire (which should be used in a guitar anyways) are perfect for this switch. Go ahead, look it up.... see what kind of fish you can find on the innerwebs!

p.s. BTW, nice find Danny! Once the internal switching logic is understood and appreciated by a goodly number of modders,, I suspect we'll see more schemes using it.

Thanks all!
I certainly thought it was a bit of a discovery. Over the past 5 years trawlling Ebay I have never seen their like before so I did indeed think they might be of interest to some. Let the crazy wiring schemes comence!

It wasn't at all clear to me either until Danny linked to the data sheet. The grey (G) terminal is common, and has the same switching logic as a standard lever switch: G-1 G-2 G-3 G-4
