Title: Cherry red switch
Post by: xsphat on Thu, 15 January 2009, 12:42:02
Without igniting another huge piece by piece discussion like the Alps thing, what are the Cherry red switches? are they clicky tactile with less click and more pressure than the blues? and is there any keyboard on Earth that uses them right now?

And lastly, has anyone here actually typed on a keyboard with them?

They are light linear switches. The force graph indicates they are lighter than Cherry browns and blues.

through force graphs ( click her for blue/brown/black (http://www.cherry.de/english/switches_controls/images/cherry-switch-keymodule-mx-en.pdf) ), I almost believe red and blue have same spring. if you trace down the line of blue mx, it is almost same with that of red ( under condition that measuring unit cN and g are same or almost same )

Sandy, I'll meet you half way and allow you to buy it for me ...

The operating forces are also similar:
Red 45 ± 15 cN
Brown 45 ± 20 cN
Blue 50 ± 15 cN

I wonder if the red stem is any different to the black.

Uh, I thought blues were lighter than browns. Cherry states in their MX switches page (http://www.cherrycorp.com/english/switches/key/mx.htm):

Linear Feel (black)
  op.force  2.1oz ± 0.7oz
  tac.force -

Soft Tactile (brown) EDIT: probably not brown but CLEAR stem
  op.force  2.0oz ± 0.7oz
  tac.force 2.3oz ± 0.7oz

Click Tactile (blue)
  op.force  1.8oz ± 0.5oz
  tac.force 2.1oz ± 0.5oz

I haven't got any blues to try yet, so I can't talk out of personal experience. I'm reading the data incorrectly?

EDIT: looks like I confused brown stem with clear stem, the data above should refer to clear stem (soft tactile, standard force) rather than brown (soft tactile, ergonomic)

Here you can see the blue and brown curves for comparison. The faint lines are the blues:

I think they are identical...I mean, same. see the picture in Black on Brown thread again.

Just for comparison, I put a picture of stems ( blue, brown, black )

Total lengs L1 and L2 are basically same. but there is a free space L3 in blue. white part with leg( twig? how do you call? ) of blue stem just moves upward without pressing force from switching leaf for a short period when the stem is pressed . while brown stem receives pressing force from switching leaf from beginning when the stem is pressed.    
this causes the deference of pressing force from 0mm point to pressure point...so I think.

xsphat, I'd like to say sorry in advance for my piece by piece observation.

Hopefully these force graph comparisons will be useful. It seems closer to the blue than brown.

xyzzy: That's not brown, that's clear stem.

That would explain the difference, as the clear stem should be the same as the brown one but with a higher force.

Looks like the clear stem is "soft tactile, standard force" and the brown "soft tactile, ergonomic", even if in some Cherry documentation I've seen either the browns (MX1A-G1xx) or the clear stems (MX1A-C1xx) referred to as "soft tactile", period. A bit confusing.

Thanks chloe and bhtooefr.
