Cherry MX Spring Modification

A few years ago, I did a spring mod of some Cherry MX switches that made it a little harder to press certain keys, but it was an imperfect solution. I don't remember how I got to looking for a single-spring solution, but I found a bunch that had higher forces than the stock 80cN springs I was using, and it was hard to decide what sort of force to go with without testing them. I went with 210 gram force springs and ordered about 3 dozen of them because I didn't need too many and they weren't all that cheap.

The springs in a bag.

While they look quite long, that was a length I wasn't concerned about since it was really more about the compressed length that was one of the limiting factors. It's slightly larger in diameter than the standard springs, but it still fits fine. This spring makes it a bit harder to reassemble the switch, but not difficult or impossible. Once I had the switch on a board, it was a lot harder to press than I thought (or tried before soldering), but it's blatantly obvious when accidentally hitting it. I think the spring moves a bit weird in the switch because the click doesn't always happen when the switch actuates, so I could've used a red or silent red or whatever instead of the blue stem, oh well.
