[Milsurplus] Un-ID Vacuum Switch

[Falls, Jim]

I found a NOS Eimac VS-2 while straightening up. Class envelope shaped like an inverted T w/fat solenoid coil on one arm of the T. All the arms have ~5/16" diameter grid posts. All mounted on phenolic armature attached to flat triangular aluminum bracket. Stands 5" high, 5" wide. Phenolic armature stamped w/diamond-shaped AEMCO logo surrounded by "Automatic Electric Mankato Minn-USA; 26.5 VDC. NOM.; 615791"

What did this come from? Anyone need it?
