Hi! Someone sells these o rings as reducing the key travel by 0,2 mm, can this be true?
It looks like 1 mm to me, what do you think?

The diameter may not directly translate into key travel reduction?

Cord size/thickness of course. The diameter is about 4 mm. Now it comes to my mind, that I could count the pixels ... cord size is 1/4 of the inner diameter, that means it is 1 mm, when the ID is 4 mm.

There are no o rings, below 1 mm cord size available on the market, right?

Well, it seems to be more complicated than I thought. The thickness of the rings above is 1 mm, but the key travel is indeed reduced by merely 0,2 mm. Does this mean, when I take e. g. an o ring with a thickness of 0,5 mm, the key travel will be reduced by zero, and the o ring has no effect, that means it is senseless?

I'm not quite sure either.

The MX slider has a platform that the keycap rests on, which descends inside the switch. The O-ring appears to be too large to pass inside the slider shaft, so the slider should stop once the O-ring hits the switch shell.

With that said, the 0.2 mm would surely depend on whether the keycap has those four support struts. They don't all (nor are the struts always the same height — they're much shorter on my Poker keycaps), and if they don't, the O-ring would surely just push further up the keycap until it does nothing?

Certainly when I tested a couple, they seemed to affect travel more than 0.2 mm — the switch throw was distinctly shorter, and mushy.

It sounds like the relevant wiki page needs a set of diagrams showing what exactly they do and how the figures are derived.

Thank You, Daniel. A few weeks ago, my first attempt was disappointing, when I ordered 2 mm thick o rings, and noticed that the key travel is reduced so much, that it actually stops right after the activation point, that is no fun typing Before I will order 1,0 mm rings, I’m trying other materials at the moment, which I find in my household.
