I think that light switches shouldn't exist. I prefer MX Blacks over the Reds, Clears over the Browns and so forth and so on. I hate light switches so much that I think that the worst part of the MX Brown switch is the 45g spring, which is too light for a tactile switch. Seriously, tactile switches have been made to PREVENT accidental keypresses, and the light spring gets in a way of that preventing.
Also, my hands start to hurt over time when I type on a keyboard with light switches, but they don't when I type on a keyboard with heavy switches.
I personally love light switches. It's odd that light switches hurt your hands, but if you're a heavy typer I guess that makes sense especially if you're bottoming out hard. I'll spend 8 hours a day typing commands on a console so anything heavy can start to hurt, though in fairness I'm probably starting with early onset of arthritis.
I also prefer heavier switches, though not any linears as stiff as blacks. If they're tactile/clicky they can be stiffer for me without fatigue. Conversely, I have made the argument various times on this forum that people who experience discomfort/pain with lighter switches probably aren't putting in the time necessary to acclimate to such a light switch.
Anything that's 45g or lighter is clearly, in my mind, way too light. I'm not sure how anybody can think otherwise unless they never rest their fingers on the keys. I think the only exceptions would be tactiles/clickies with enough of a tactile event to prevent accidental actuation. I think maybe 45g Niz switches are probably a good example, though it has been a while since I have typed routinely on them.
Ironically, I often type from the time I get up to the time I go to bed, and can do so with box navies just fine. I feel more like I'm fighting the keyboard with a lighter switch than a heavier one. If the switch is too heavy I don't feel confident that I'm going to register a press every time, but that's preferable to me to feeling like walking on eggshells to avoid accidentally actuating keys you didn't even mean to. The only thing that can tip the scale is if a switch is so stiff that it causes fatigue. MX blacks and membrane buckling spring used to do that for me. It appears that they no longer do, but I'm still not confident typing with them either way.
Quiet around here, so here goes....
The spacebar is TOO DAMN BIG.
I'm in total agreement. You should really be typing pretty close to in the middle of it anyway, so most of it is literally just wasted space. I see a lot of kids in the schools I work at typing on the extreme edges of it and wonder how that could even be ergonomic.
i dunno, 6u seems a bit small to me 10u looks like the sweet spot
joking aside, i think that given i only use my right thumb on the bar i feel a 1.5u should be usable, but i understand the large space bars and find that often 7U layouts look cleaner.
I just used that for over a week.
I think I would be fine even with a 1u space bar. Might take a tiny bit of adjustment of muscle memory, but maybe not. Never tried any of those high speed low drag layouts.
