It's a single pole. double throwswitch, with a non-typical use of a 3 pin XLRconnector, that seemingly gets signal up a pin and routes down one pin or the other, switch location dependent.
Power comes up one of the 3 pins, goes down a 2nd for one "state", down the 3rd for the 2nd "state". Presumably ground Is present at the lamp(s) to complete the circuit, thus not needed at the switch.
Microphone decontaminator. I'd store it right next to your par lamp oil and your ID-10t's for easy access for when your new techs need something to do.

Looks like the manual trigger for a ProjectorDowser known as "The Flapper". The older styles had this type of switch in this type of box. Perhaps you have the other end somewhere?
I recently discovered, that the color on rosco or leegel(cannot remember which it was) is alcohol soluble. So a new generation of interns can wash the dirty gels!
So, if what you have is a hammer, everything looks like a nail...
But it seems that if you took a standard Clear-Com XLR-3 and shorted power (pin 2) to ground (pin 1), you'd have a decent Remote Mic Kill for everyone on on that channel.
If you take power and shorted to audio (pin 3) you'd have a call signal, albeit with a big THUMP noise associated with it, if you don't add a voltage regulator.
Though it sure looks like a projectorshutter controller, if you want to use it elsewhere, it'll probably make a fine Remote Mic Kill / Call Signal box for single channel intercom.
