"Universal" footswitch

[newey]

I have one of these "universal" footswitches for my amp. It only switches the gain on/off. It is a "latching" type:



Note that it's just a TS plug. I wanted to find out how it worked, so I removed the rubber base to look at the switch. It's apparently a DPDT, although only 1 lug seems to be connected. I know, that doesn't make much sense, there must be a ground connection I'm not seeing. But it's tough to see much inside, and I didn't want to further dismember the switch.

Doe anyone know, would this be a NO or NC switch? Does it simply connect (or disconnect) the sleeve from the tip? Basically, how does it work?

I'm thinking of another use for such a footswitch, but I need to know how one of these operates. Visual didn't help, and the googles are failing me.

These switches do normally work by either connecting the sleeve to the tip or not. If it is in fact a latching switch then by definition it is neither NO or NC. Those terms only make sense in the context of momentary switches.

Edit - Now that I think about it, even a true DPDT momentary switch can be either NO or NC - or even both at the same time - depending on how you wire it.

Put your meter across the plug (one probe on the T and the other on the S) and switch the thing a couple times. Should answer something.
