We have a bunch of MIL-SPEC switches but they take T1-1/2 T5.5 telephone slide base lamps rated at 12VDC and up. I would love to run them directly from a microcontroller board!
I actually went so far as to line up a Korean firm to custom make these (highly recommend them).
Tonight I attempted to replace the bulb with a white 3VDC LED. It was easy… I performed and tested it twice in 5 minutes… only 62 more to go!
