Title: Peerless
Post by: Mr.Zergling on Tue, 08 March 2011, 00:37:31

So, I've rediscovered my ancient Fujitsu FKB4700.....

I was wondering if these switches actually count as mech, just cause of the rubber domes.

Sure feels alot better than my lycosa, and I'm gonna start using it on my main comp once my AT to PS/2 adapter comes.

Pull out a keycap, take a close-up picture of the switch under it and show the picture here. Within 10 minutes you will get an answer.

The Fujitsu Peerless mechanism is pretty well documented. A pretty unique contraption. Since most anything that is not a standard rubber dome, flexible silicone, touchscreen or laser keyboards counts as "mechanical" 'round here, I'd guess it also does.

I'd be more interested if they weren't reported to (a) be on the heavy side of things and (b) exhibit problems with RShift once in a while.

Keycap actuates spring, spring actuates plastic cup, cup actuates rubber dome, rubber dome actuates membrane.

The interaction of the cup (with the spring) and dome is what provides the tactility and clickiness.

I don't find it to be heavy at all, but that may just be because i have really strong fingers, and its my Lshift that has a problem,.
