What kind of switches are these and who sells them?

Mmm.. I've never seen something like that.. Don't really know where you could get them. Maybe you could dress a regular DPDT to make it look as that one

[oskar]

What indeed?!
I actually do think I've seen something like that...
Doesn't it look like some kind of multifunktion gizmo? A potentiometer with a pushbutton on top?
Or a two stage pushbutton?...

Those guys on experimentalistsanonymous.com use them quite often.

It kinda looks like a homemade actuator - the kind people do if they want to use those little tact switches.

I had a bunch of thoes as a spst switch. I bought a huge lot of parts at a flea market. They were really old I am not sure if they are still made.  I dont have a use for them so I gave most of them to Dan of 4ms fame. No doubt he will find a good use for them.

they look like some spst foot switches ive seen before, those ones are probably momentary, cause that thing obviously has to be an amp channel/effect switch
