Some time back, I bought a Fujitsu FMT-KB202A tenkeyless keyboard to be used with an FM Towns computer. When taking ti apart for cleaning, I found leaf spring key switches with a membrane combination. I couldn't really find it in the Wiki so I think this can be coined "Fujitsu Leaf Spring 4th Generation"?

Hmm...interesting, thanks for sharing. I've seen this keyboard online many times, nice to see the internals for a change. Nice tombstone keycaps.

I should check to see if I have any keyboards that use this switch.

These keyboards are unusual and cool. I like how they are different from the (boring) IBM-PC norm.

I wonder what the keys on the bottom row are. One of them must obviously be the Backspace key.
(I sometimes wish that you could enter pictures into Google Translate... )

I think it would be better to give it its own page and call it "Fujitsu leaf spring over membrane".

Yeah, this is probably the last cost savings Fujitsu did on this mechanism. I have a bunch of keyboards using it from the early 90s.

Ah yes, this model, I've seen a few of those. Very nice-looking boards. And yeah, looks like you've discovered (another D:) new switch type! 4th-gen FLS sounds good
