Nice man great breakdown.

Hm, I have some of these NOS, and I guess I'd rate them 17 out of 20 for smoothness. Good, but not perfect.

Are yours lubed, Daniel?

Yes, I saw some on AliExpress, but they were much too expensive for me. Do you have then in a keyboard as well, or just as loose switches?

No lubricant that I'm aware of. They're just loose.

Nice teardown. What keyboard did the 1st gen switch come from?

Nice,

This is the switch you said gaming on is fantastic right?

The third gen, yes. Which is arguably even smoother than the first one (which makes sense because it's a lot lighter).

My Tandy 3000 (FLS 3rd gen.) has factory applied switch lubricant, which may make it perform significantly better than other keyboards with FLS switches.

Interesting because my clicky FLS 1st gen don't feel very smooth but mine are obviously not NOS.

Agreed, in fact I'd say 1st and 3rd gen are not even comparable really. My 1st gen (clicky) feel like a completely different switch not related in any way to my linear 3rd gen FLS. I've never tried 2nd gen although from the wiki I gather they're quite similair tp 3rd gen.

I find this hard to imagine since mine are silly smooth but possibly mine were lubed also.

As a note, mine do click. It's like reed switches: a very subtle click that you can hardly hear. There's only a click on actuate, not on release.

Chyros · 02 Jun 2017, 23:23

Mine click a ell, although I'd ay it' clearly not intentional.
