Spring differences?

[effectiveduck]

Is there any differences in the various 55g and 62g korean springs around?

Specifically is there any difference between the ones sold on GON, Winkeyless.kr and Originative.

And if there is what would people recommend?

Thanks for the help.

I've got more springs than I'd like to admit, and to be honest I can't tell? A friend and I tested kbdmod designed 55g and the "limited" ones from Originative fwiw.

Also dug up an old e-mail, where I asked the difference.

It has more elasticity. That one was designed by Korean Community while the non limited was designed by kbdmod.

Perhaps my fingers are busted from all those years of rhythm games.

This particular threads a good read too.

I didn't think there would be much of a difference, at least not enough to justify spending extra to get a specific version.

I'll probably just get them from wherever I order other parts. Thanks for the help!

As far as I know,  the I only difference is in the gold plated springs which end up about a half gram heavier.

I don't know about korean springs or chinese, although I do know that the difference between black and yellow gaterons is the spring.

Black gaterons have a uniform spring coil resulting in uniform force applied all the way through the depression.

Whereas yellow gaterons have a variable spring coil, tighter on the outside and wider on the inside, resulting in a 'tactile' linear switch, you can feel the force required for actuation change through the depression.

Both are 55g but they feel different. I tried looking up some pictures to show the difference but I can't find any that looked like the spring in my switch. If someone wants me to take some photos I certainly can

Huh, I'd been wondering what the difference between gateron blacks and yellows was, pretty neat idea with the yellows.

Whereas yellow gaterons have a variable spring coil, tighter on the outside and wider on the inside, resulting in a 'tactile' linear switch, you can feel the force required for actuation change through the depression.

This is what is called a progressive spring rate, all other momentary switch springs I know of from F BS, M BS, Alps, Space Invaders, Cherry, Kaliah, etc, are a linear spring rate.  I am referring to the metal coil springs only.  For example, lets increase the numbers to make it easier to understand and type.  Lets say you have a spring with a 1 pound per inch spring rate.  It takes 1 pound to depress the spring 1 inch, 2 pounds for 2 inches, and so on.  On the progressive spring rates, 1.5 pound for the first inch, 3 pounds to get 2 inches, 4.5 pounds for 3 inches, etc.  This can be accomplished a couple ways, but the easiest is by varying the distance between coils.  The closer the coils, the lighter the spring rate.  However, this comes at the cost of reduced travel.  The one other cavet with this is to get a truely progressive spring rate, it requires constant changing of the coils per inch.

There are other patterns that spring makers can do to alter and shape the graph of the spring rate.
