Topre switches are so new that they're still tough to find. They act as a hybrid between mechanical and membrane: A rubber dome sits over a spring that creates a capacitive circuit when pressed.
more of your setup is shown than the keyboard itself
what do you guys think about this new switch that came out recentlyhttp://www.amazon.com/Topre-Type-Heaven-104-key-Keyboard/dp/B00DGJALYW
I'm typing on a Topre right now. Super smooth action, smoother than my Cherry MX Blue. The 1mm operation point and fast debounce are pretty nice, though most people would probably be disappointed with it since the actuation force curve makes it feel really similar to a typical membrane keyboard. It's not quite as stiff, though, at least not these 45g domes.
