Push-pull pots are a useful gadget for adding switching to a guitar, without drilling or changing appearance. They generally include a built-in DPDT switch. In wiring up the switch, my understanding is that there are two versions, in one case, pulling the knob out connects centre lugs to the lugs nearest the switch body (based on a slide switch mechanism), while the other, based on a toggle switch guts, connects the centre lugs to the rear lugs when pulled out.
Either can be used for a given purpose, provided this convention is taken into account.
My questions are , is the above summary true? and if so, which type is more common, and therefore a better choice for putting on wiring diagrams? - this is raised following Runewalkers experience with the Strat-lovers Strat.
cheers

John,
i'm only familiar with the version that acts like a slide switch.
i don't know if the version that acts like a toggle is common, rare, or a myth.

John,
I think in Oz (at least here in Adel) toggle is more common...I have used the push/push variety, which I find more suitable when using Strat style knobs...
...interested to see where this goes..

hi Gumbo,
welcome to guitarnuts2.
i'm curious about the pots that are available down under.
the ones with DPDT push-pull or push-push, are they full size, or mini-pots?
cheers,
unk

Thank you Unk..
The stuff I've bought is regular CTS-sized (as in Strat)....just back from work and no time tonight to dig stuff up, but I'll have a better look through my stuff at the weekend, and see if I can be more specific...yes, BTW, they are DPDT toggle..

Hi Unk...
..just got to measuring an example that I had lying around....I think this is the same as I have used in the past..but I think I stand corrected..the pot body is 16.5mm (that's a shade under 21/32"), so I guess that's mini?
..comes with a split shaft to suit standard Strat knob...switch is DPDT with a ground lug on the case..the one I'm looking at is marked WSC A250K....I can make more enquiries from my supplier when I see him next week if you want...
Regards
Gumbo

......I can make more enquiries from my supplier when I see him next week if you want...... for me not-so-much. i have no problem finding (Asian) Alpha minis with DPDT switches on them. it doesn't matter that they are like slide switches. the only full-sized pots i was able to find so far had only SPST switches. thanks for following up on that. unk |

unk, I'll see Craig tomorrow and pump him on that one...just in case..
....sometimes it's interesting what turns up down here....perhaps we're a natural dumping-ground for obsolete equipment, governments and nuclear waste......:-)

Dear All...
...here is the latest....(from Craig today)
(1) He has also only seen the 'mini' version around (which he's currently selling at about AUD20)..available in both A250k and A500k......he pointed out to me that these have the same threaded-section diameter as the std pots, whereas the push-pull ones he has have a smaller diameter...in relation to the diameter of the mounting hole in the pickguard.......
(2) he remembers seeing (he is pretty sure!) recently a 50th Ann Strat which had (at least one) push-push pot which used a 'split' version of the standard Strat knob....apparently the centre of the knob actuated the ?PDT switch, while the outer (numbered) section obviously did the usual busines...he said that this was EXTREMELY neat, and looked like it was a factory-fit. It almost had the characteristics of a concentric pot, in that the numbered dial remained at a constant height from the pickguard....independently of the operation of the centre section...
....curiouser and curiouser....anyone seen/heard of this???
....I guess this doesn't actually answer too many questions, rather it probably poses a few more, but...:-)
Happy to put whoever in touch with whatever, although I will be off travelling in the Eastern (Oz) States until mid-next week...talk after that.
Regards to everyone,
Gumbo
