Surplus Military switches acquired circa 1980's ranging from SPST to multi-tier rotary.
Well... Not much here. Remember this is a research lab not a store. There is enough variety to support a small development team. And that's about it.
There are push, slide, toggle, keyed, keypad, rotary, linked, synchronized, dip, etc... There are single and multi pole. And single and multi throw. Some are circuit-breakers or have projected displays as used in high-tech aviation. There is variety not quantity.
There is of additionally a few more small caches that hat were not accessable for documentation. I'm going to estimate that there are about 500 switches in total with the vast majority being unused.
