Diagram question.

[JRCorp]

With my first attempt at wiring my guitar up, I literally did everything backwards (mirror image) of the diagram provided by Seymour Duncan, thinking it was appropriate for working from the back of the guitar. :banghead:

So, to make sure I get things absolutely correct this time, I want to clarify what an SD diagram of a push/pull means.

In a diagram such as this, which switch posts are which, if looking at an actual pot such as this?

I had thought that the upper 2 posts in a push/pull diagram were the bottom 2 of the actual pot, as if one were looking down the side of the pot from a top-down view. But judging by what the diagram says, I would think the opposite is true.

:thanks:

Re: Diagram question.

i sympathize with your confusion ... from looking at the diagram you referenced, i cant tell you with 100% guaranteed accuracy how it is intended to be used

but here's the thing ... i highly recommend that you use a multimeter to test out the functionality of the push/pull for yourself .... it isnt hard and it is really the only way to know with 100% assurance how the actual unit in your hands will work in your actual implementation ...

if you get a digital multimeter it will likely have a little beep 'continuity' test function ... this will let you know which tabs of the switch are connected when the switch is pushed vs pulled .. even without a beep function, you can use an old analog meter to test for zero ohms (connected) or infinite ohms (open)

good luck

Re: Diagram question.

Thanks, t4d; I'll definitely have a go with the multimeter.

I'm guessing by looking at what the diagram says (single-coil in up, humbucker in down), that the 2-dimensional picture, top to bottom, literally translates to a 3-dimensional push/pull switch, top to bottom.

...aaand the push/pull works as I would guess looking at it - up is top 4 posts, down is bottom 4.

Re: Diagram question.

yeah, i think so

the way i visualize a switch like this is that there are two columns each with three posts ... each column is an independently operating electrical switch function, but the two columns are controlled by a common physical switching mechanism ... the center post of each column is going to be connected to either of the end posts depending on whether the switch is pushed or pulled ...

Re: Diagram question.

Yeah, man, that's a great way of thinking about it. I feel like with doing the wiring a few times over, looking at diagrams, and reading, I'm beginning to understand how stuff works better.

Re: Diagram question.

Hi, on the diagram the two posts on the push pulls closest to the pot are the ones closest to the pot in real life i.e. for the diagram you posted the posts with no wires the one ones furtherest from the pots and are the ones at the bottom of the picture of the push pull you posted.

Hope that makes sense?

Wire it up, and if the switch is the wrong way around just leave the middle post alone and switch the top and bottom one.

Re: Diagram question.

Well, if you're right, Mark, then I've already wired it wrong today. It's not a big deal, 'cause I've got to go back at it anyway, but I'm going to take it easy for a bit. I thought I had it right, too. Thanks for the tip.
