Alright, I've constructed a nickel tester out of the key tester and some leds. I used 7 red switches with their springs replaced. The keycap being used weighs 3.2 g so it's a little off, but it's the flattest key I have without sanding one down. The weight listed will be where the LED turned on.
For the sake of simplicity, I'm just rounding up the keycap to count as another nickel. You can see in the first switch that it activates with either 7 nickels or 6 nickels with the switch so it's probably somewhere in between the two, but if someone wants it more accurate I'll figure that out later.
I hope this will help rather than make more confusion, but let me know if you have any questions.
35 g spring - 35 g
40 g spring - 40 g
45 g spring - 45 g
60 g spring - 60 g
62 g spring - 65 g
67 g spring - 75 g
80 g spring - 80-85g

Thank you AlexPeterkin for your very helpful post!
F84526542Most of what I see there lines up with what I've been taught, except for the whites. I have more experience with whites than most people. It's my preferred switch (when I find a batch that's not one of the highly inconsistent batches) and I can't say with 100% certainty that it's wrong, but I would bet a LOT of money that greens use heavier springs than whites. Whites are actually somewhere in between a blue and green in spring weight, according to my senses. It's not just that they have a softer click. Maybe I learned wrong, but here's what I was taught regarding actuation forces: red 45g, brown 45g, blue 50g, clear 55g, black 60g, white 65g, green and grey 80g, and dark grey (linear) 85g. I even have a chart that shows them having those weights.
AlexPkThank you very much for the analysis. That means the 62g are NOT the 62g that modders rave about in "62g Ergo Clear." Appreciate the effort and the photos. Still in for those 35s :)
sordnaNot a problem :)
On Monday I'll see what it takes to bottom these out, but it looks like the listed weights are for actuation. At least in a linear switch. I can say just based on clicking them a few times that the 40 g and 45 g springs felt most like the natural red which makes sense if it's actuation force.
Hope this helps!
DefectThis would seem to be the case. On Monday I'll see what the bottom out weight is on these. For science. Maybe one of them is pretty close.
And no problem. Any chance to build some led rig and run experiments. :D
AlexPkAre these springs short or long in length? How about the thickness of the coils? Some cherry springs, like clear and tactile gray, have shorter springs with more space between the coils causing the compression force to become very high after actuation. (near 100g for stock clears)
A similar rated actuation force could result in a very different feel depending on the length and stiffness of the spring itself and its compression force. (especially for typists who intentionally bottom out)
I guess we'll all just pick what we think feels right and hope we get lucky lol.
DefectNone of these springs should have a force curve, Hooke's Law. These are linear springs. It might be a perceived curve as you pass the bump in a tactile switch but the springs themselves are linear, no?
