The switch is a push pull and normally it's wired up so when it's in the down position it is off and in the up position you've engaged whatever you have switching.

It's a NO switch. In other words, in the normal position (pushed down) the contacts are open. Pull up, and the contacts close.

Yes, it could definitely be used as a guitar volume if the value is what you require.

This is a 1/2 watt pot.

The two bottom lugs are simply used to make (when the push-pull knob is pulled up) or break (when the potentiometer is depressed) a separate connection. They do not have set polarity.

The switch is closed when pulled out and open when pushed in.

Hate how much play there is in these pots as you're turning the dial. For example, on my amp, if the pot is on 3 there is so much play that the dial can flop around from almost as far as 2-4 without actually changing the volume. Another way of looking at it: Being on volume = 4 is different depending on if you approached that point from a lower or higher volume.

I agree with the other poster, this thing is junk...I installed it and the pot itself would not work...I set it up as a push pull cathode bypass switch on the volume control...the switch part worked fine but not so the pot...

Avoid this potentiometer at any and all cost,they’re complete junk.
It’s cost me well over a $1000.00 in return shipping and other cost and damages done to customer relations because of these failures.
Look for a better way to switch as these mechanical switches are going to fail miserably shortly after they’re installed..
