Title: Where to purchase a few Cherry MX green switches?
Post by: shawn o on Sat, 28 April 2012, 14:04:59
Would like to get my hands on a few if possible?

Can't you just go getto? (black springs with blue stems)

Yeah just frankenswitch it. Actual greens are hard to source at the moment, the switch buy has eta of February... or just get whites, they are only 5cN heavier and easy to get right now.

Whites are weird compared to green.  It's more than just a 5cN diff.

CHERRY BRUISE

Much better name than "ghetto greens"! :D

My greens and whites have exactly the same spring. They also feel the same.

I shall have to mount some on my plates and put keycaps on them for more proper testing.

Are you sure of that DV?   Do you have loose switches to do a head-to-head test?   Just push the 2 different switch stems against each other slowly and watch who wins.  Looking at a spring will not tell you how similar it is to another spring.

Yep, I compared them head-to head. from the 110 of each. I have much less greens, now that I've put them in my plate, but I still have some loose ones.

I'll try it again, and post pictures of the springs/guts disassembled. Not Super HQ pictures, mind; (with my cheap refurbished point&shoot) but I should at least have clear ones on white paper.


Wow, just took a ton of pictures. The springs do seem to be the same (same number of coils, same number of rotations). The sliders appear to be the same (and amount of motion, same bump size/shape). Frist time using the "small currency mass force test", I cane up with the white ones being one dime lighter! I then repeated the test trying to eliminate off-axis loading, and got the same mass each time. (it held at 12 nickels and 10 dimes, and actuated at the 11'th dime every time, excluding eccentrically loaded cases, That's 82.68g (https://encrypted.google.com/search?hl=en&q=12%285G%29%2B10%282.268g%29#hl=en&sclient=psy-ab&q=12%285g%29%2B10%282.268g%29&oq=12%285g%29%2B10%282.268g%29&gs_l=serp.3...43577.43577.0.43684.1.1.0.0.0.0.71.71.1.1.0.les%3B..0.0...1c.Lw6LhxPcd9Y&pbx=1&bav=on.2,or.r_gc.r_pw.r_qf.&fp=4c5ca94259600d8c&biw=1024&bih=631) and 84.948g (https://encrypted.google.com/search?hl=en&q=12%285G%29%2B10%282.268g%29#hl=en&sclient=psy-ab&q=12%285g%29%2B11%282.268g%29&oq=12%285g%29%2B11%282.268g%29&gs_l=serp.3...48094.48094.1.48229.1.1.0.0.0.0.81.81.1.1.0.les%3B..0.0...1c.GzaYNGoK_3A&pbx=1&bav=on.2,or.r_gc.r_pw.r_qf.&fp=4c5ca94259600d8c&biw=1024&bih=631) for those interested)

I'm uploading a ton of pictures to photobucket, and I'll just share the album. I'll post the money shots as higher quality ones on imm.io or upload them here.

Edit: Looking at the pictures, I think it might have been the diffrence between 9 and 10. Both held up 10.

After testing, I did note that the white was easier to actuate with 10 on it than ther green. This can be for one (or more) of several reasons:

1. The slider is black, perhaps it has some lesser amount of friction (doubtful, as the metal crosspoints don't really add that much force)
2. They are different by some factor I do not know
3. They are the same, and the 2 or so gram difference is just manufacturing tolerances (2.3% difference isn't really that much).
4. Experimental error (more vibrations caused my the white being at the edge of the board, etc.)
5. User error. (Maybe they were the same, and it's just me expecting a difference, and seeing one).

I would also like to note that both the fully loaded switches were easy to actuate with vibrations, breathing, etc. They could hold the weight for some time, though. (Up to a minute, I would imagine, until stray vibrations, etc moved them.)

If you want, I'll run a multi-factor analysis with an ANOVA table and everything to try and see what exactly the issue is. Unfortunately, since my measurement error is so high, I'd need more precise weights and scales to be able to draw any sort of conclusion from it. Given those weights or scales, I'd happily do this. I enjoy engineering tests.

i was under the impression that whites had a tactile bump similar in size to clears in addition to the clicky slider.
They looked the same to me. You'll be able to judge this for yourself from the pictures I took several, and only some are appreciable blurry!


Pictures incoming.

"small currency mass force test" pictures to be added later.

After some more subjectivity, the "click" on the green I tried just now does sound like it might be a little more loud, sharp, less dampened than the white.

That's really odd, I no longer have the white or green switches, but when I did my tests they were different (I don't remember in which direction honestly).

I noticed nothing different between white/blue sliders except the color of the plastic and the clicky noise being less on the white.

do you know if thats a result of a difference in the slider or if the spring makes the difference? trying to decide if i want to go with whites + lighter springs for an upcoming project.

I might have ~50 extra greens at some point in the future. I bought 110, to mod my G80-3000, but sold it to sth, so I just ended up with a bunch. I'm trying to decide if I want to put them into an ergodox or just sell em. But that is irrelevant, as they are 3000 miles away. :P
