Have a ton of these switches that need to be put to use.

For the unintroduced (like me), apply 12V to the black leads and this SPST switch jumps to the opposite side. Remove the 12V and it goes back to the original position. I've even had it work with a 9V battery.
Great for situations where you want two antennas on the roof but only want one feedline in to the radio room. Or thousands of other uses. These are working pulls from medical equipment. I'm sure there's a datasheet somewhere but I can't find it.
