Man, I don't know a lot about these, and they are also one of the retro switches I haven't bothered to try opening, but I found a picture of the internals from Deskthority so that's fun. Telcontar.net calls these a clicky, although mine feel more like a squeaky tactile, and they squeak on the way up. I don't really understand these but I they fit very well in my pile of odds and ends for this week.
