What was the source for the light and heavy springs? Which switches exactly?
What was the source for the light and heavy springs? Which switches exactly?It says in the OP what switches.
all those types got averaged together.

That's how I read it but I can see how the confusion can arise. Some clarification would be nice.
rknize, how consistent were the springs in each batch? Meaning, what's the standard deviation? I hope you saved the data for the 20 springs before you averaged them.

...
The tolerance of the "heavy" and "light" set are within that same margin of error.
So here's the thing, guys. We all know how things work in the corporate world. Designers may have hopes, dreams, and expectations, but then the bean-counters come along. There may have been a time where blue switches had slightly different specifications than brown switches. In fact, I am quite confident this is true since I have seen and felt different springs from old Cherry keyboards (the whole "vintage" Cherry thing).
If it was a more vintage spring, then it makes perfect sense. I have vintage blacks in my Phantom and they are lighter than blacks that were in my first QFR.

I have a 65g and 67g Korean spring I can send you if you want to test some additional springs.
I am kind of surprised by your Black vs Clear spring findings though. I'm typing on a keyboard with Blacks right now and have a keyboard with Reds and Blacks with Clear springs in them, and the key switches feel heavier with the Clear springs than the Blacks.
As I said, I have set this aside for the moment so I can get on with some other projects. For example, I still haven't built my LZ-GH. :(
That said, I have a couple of other sets that I am going to measure as specified in the OP. If there are other springs that folks would like to lend me for the cause, I can measure those on the same rig. While its accuracy may be questionable, it has proven to be relatively precise which makes comparing them meaningful. I'd like to see at least 20 samples to gather meaningful data for a given type.

Given how soft the springs are and how short the switch throw is, I doubt the winding effect of the spring could overcome the friction at each end...even if they are lubed. I did not note any movement in the rig.
I don't understand. How does originative 45g have more k(g/mm) than originative 55g ?
It seems that the last OP post was on 2013; it is not clear if he is still working on this.Yeah, but I saw some replies from early this year so in addition to the props for the work, I thought I'd throw it out there.
Absolutely fascinating work. :cool:
Have you had a chance to try other springs like one from a buckling spring? I bet a graph showing the differences in springs between an IBM M and IBM F would be just as interesting, especially to compare to the Cherry springs.

OK, will do. :)
Being forced to use the same keyboards for over a year was kind of a good thing. I picked the right ones (BS and ergo-clears). Playing around with some of the other boards makes me realize that I should probably sell some of these others.
OK, will do. :)

Sweet.
I'm currently collecting various switches and setting them aside for you when you're ready. :))

Hmmmm... That's not a bad idea. I'll have to see what I can do.
Please post a picture of the various switches do you have, it would be very cool to have it along with the spreadsheet.

Images not working for me in Safari or Chrome on OS X or Safari on iOS. Does indeed appear to be an SSL issue - I can see the images if I open the links separately, just not inlined in the thread.
OK, was missing www in the cert. Should work now.Thanks!
