Seller says they purchased these switches loose in a mason jar, so IDing them is unlikely unless I stumble upon them independently.
It is a very tall, cap is thick doubleshot, and the reed's return chirp is very loud. No idea what the screws on the top are for as they don't screw into anything or hold anything down.

But the switch mechanism is different. Definitely looks like it's from a calculator, typewriter or a control panel of some kind (basically anything that isn't a conventional computer keyboard).
