Out of curiousity, what types of switches would everyone be looking for? I've got a quote request out to a few places for pretty much all the common colors, but it would be helpful to have a bit more of a solid idea.
Short answer: I'd order Cherry MX Red switches.
Long answer:
The most important mandatory thing for me about switches
is that I have to be able to open them up, take off the covers,
so that I can change/modify the stems and springs.
Since you are dealing with hand and wrist pain,
you may have looked into low-force switch activation, so
you may already know about Tim Tyler's stem & spring surgery
on Cherry MX switches, where he achieved an activation force
of 20 grams. I duplicated the 20 grams, and so can anyone.
Pcb-mounting is best if you want to do that easily.
If you cut down Korean 45g springs, you can
get an activation force of 15 grams. I've done it.
That is helpful for hand & wrist pain.
If you cut down Korean 35g springs
(I can't find them anywhere) I'd bet money that
you will be able to get an activation force of 10 grams.
That will be even better for hand and wrist pain.
When going for low activation force, the linear
Black or Red stems work best. Since Reds have
springs with lower activation force than Blacks,
I'd order Reds.
But it's not a deal breaker, because
changing stems & springs is easy with pcb-mounting.
