Title: Cherry MX Springs vs Korean Springs
Post by: Index on Tue, 18 December 2012, 16:56:19
I was looking at the Cherry MX page on the GH Wiki and I saw that putting a 55g Korean Spring on Cherry MX Blues makes it lighter. Well, at least that's how I interpreted it. Now I'm just confused, because I thought the springs on the Blue/Red/Brown switches are rated at 45g. Is there something I'm missing?

I was confused about this as well.   What I've read is that cherry springs are rated by the force required to actuate whereas Korean springs are rated by the force required to bottom out.  A 45g cherry spring is comparable to a 62g Korean spring.  Therefore a 55g Korean spring is lighter than a 45g cherry spring.  I've also read that gold played Korean springs are "springier" than normal Korean springs. I am impatiently waiting for Sheryton to get his new website up so I can order 2 or 3 hundred 55g springs.

Stock MX springs are rated around actuation, so about half way down. Korean springs are rated at compression. So a 45g spring from mx blue/red/brown is about equivalent to a korean 60g spring. The 55g springs I have are indeed lighter than a stock red spring, and the 62g spring is ever so slightly stiffer than the stock red spring.

Are 62g the highest weight Korean springs?
no just the more commonly used ones. if you read WFD's previous post youll note he mantioned 55g, I believe they range from 50g to 65g.

I am interested in these Korean 55g springs too.

What other versions are available?

Where would I get them?

No one reads anymore do they...

I believe Korean springs range from 50g to 65g. (somone please correct me if im wrong)

Post in the classifieds see if someone will sell or trade you or bug Sherryton to start selling his.

Do you know where I can get some 62g springs?

(I kid :P)

Oh are there Korean 50g springs too? Lowest I've seen or heard is 55g. Do you have a link to anyone using a 50g korean spring?

Ah! I finally fully understand! I was trying to guess what 62s are at. I hear 62 blacks a lot so I assumed it was around a black. Has anyone done a Rip-o-meter on just the springs fully compressed? Mhh springs. I found a random spring and put it in my mx black and it was quite amusing. (it was heavier)

Given the narrow diameter, and also to account for possible variation, I recommend taking measure on three or so springs (at once) to balance the load.

Good idea. How would you hold the spring from flying?

On a side note: three is a great number!

A jig... you take a small board and drill 3 holes to stick toothpicks in, then a matching board with bigger holes for the toothpicks to slide through.

I think there are 45g springs too.

So that would mean 45g to bottom out? Holy hell.

Never typed on a buckling spring before, have you?
(Yes, about 40% of my volume is bottoming out 80g buckling springs.)

I meant to emphasize that 45g to bottom out is not a lot of force!

And I have indeed typed, even extensively, on buckling springs, as my parents got a ps2 in 1987. Actually my mom still uses the keyboard even now, ha. Who knew mom was so cool? I only learned to differentiate/appreciate mech keyboards a year or so ago.

Where would one get Korean springs? I'm going to do the ergo clear mod when the WASD V2 comes out and I was wondering what kind of price point I'm looking at. (plus a reference point for the future)

Supposedly they might even go as high as 67g with the Korean springs.  http://www.kbdmania.net/xe/index.php?mid=purchase&document_srl=6027801&6027801_cpage=1

Do you guys find it odd that in keyboard world, we use 45g of force as a measurement? Really, grams is weight, not force, at least in engineering terms.  It is basically keyboard convention, but it is actually an incorrect way to refer to the pressure required to actuate. I find it kind of interesting.

There are a lot of weird science terms that aren't quite used right.  I think it's easier for most people to use that instead of calculating the Newtons.
