Hmmm, using different length springs is smart.
Fun fact, the only different between Halo Clears and Halo Trues is the spring length/strength. The stems are the same! And if you used both of those before, you will definitely know the impact of changing the stem length can be (for tactiles).
As for linears, I’m not sure how well these will work or matter if they will work. The stem will return to position faster if preloaded I suppose, but isn’t it otherwise the same as just starting partway through the press force-wise?
With that in mind, my initial hypothesis would be:
On a switch with an extra long spring, the initial force of the press would be greater than a switch with a normal length spring. In addition, the difference between initial and bottom out force would have a smaller delta compared to a switch without a longer spring.
I also could be completely speaking out of my ass. I didn’t major in physics, and I barely remember how to use F = -kx
