At the request of Chyros, the next switch to measure is the USw LARB01.
(again, thanks Daniel Beardsmore, this one is also really interesting :mrgreen: ).

It's strange because anything with zero preload should be really wobbly, but I don't recall these having a wobbly slider.

So maybe that rules out the idea that preload stops the slider from wobbling up and down from lack of spring compression.

Heheheh, well, that confirms a few things I had in mind about these xD . A very interesting curve, thanks a bunch for measuring these, Jacob! :D

That curve goes so close to zero, that you'd think that if there was even a speck of dust inside, the slider would simply stop part-way through the return stroke.

I do have some switches that fail to return; one is CL-1145, which I did include. (I realise now that I also forgot vintage APC green, which is not a model that Tai-Hao still remember.)

I wonder if CL-1145 also comes so close to 0 gf that this is why it's able to get stuck the way it does. Those are used switches, while LARB01 is all new/NOS.
