I know, I know, this title doesn't make much sense. I came across an interesting board today. It has plate mounted 'switches', but none that I've ever seen before. I have various ALPS, Cherry and many Buckling Spring boards, but these are very unusual and different.
The key caps have a rubber dome inside. The cap clicks onto the stem on the switch and the rubber dome pushes the cap up. Push it down and the switch makes contact. Release it and the rubber dome pushes the cap up again. It feels like a rubber dome and looks and works much like a regular rubber dome board, so why are these things plate mounted? Any idea what these are? If intrigued enough I may just buy the board for $10 and experiment with it a bit.
