Actually useful Cherry MX catalogue?
Posted: 25 Oct 2014, 16:37
Has anyone got a brochure or catalogue for Cherry MX that doesn't completely suck?
I've gone through all of mine and I can't find one that:
a) Lists every switch on sale
b) Has the force curve for each switch
For example, my March 94 Keymodule MX brochure gives the force curve for "MX with tactile feel" but does not cite any part numbers, so I cannot be certain which switch this is for. This is the graph that people use for clears, but I can't prove this from catalogues, as Cherry were forever changing the English language names of their switches (the same catalogue uses "Keyswitch with soft tactile feel" and "MX soft" on the same page: three names for one switch on the same frigging page) and failing to cite actual part numbers anywhere.
It also only lists five switches, and in 1994 there were surely more than five varieties on sale.
In particular, I wanted to cite for certain the tactile, peak and terminal forces for MX Clear here: [wiki]Force[/wiki] (the first section of which, I have just rewritten and illustrated). I have Clear switches in datasheets, but not with force curves! Cherry also never cite the terminal force in their specifications.
On the wiki, [wiki]Cherry MX Clear[/wiki] cite as 65 cN actuation, but as "MX with tactile feel"—if this is indeed clear—it will instead be 55 cN actuation, 65 cN tactile force, and a terminal/peak force of something like 95 cN.
