I’m really liking the Halo Trues I just got so far, both from the perspective of the smooth tactile feel and their effectiveness at preventing me from bottoming out — the fact that the bottom out force is 40g higher than the peak tactile force and 46g higher than the actuation force, and the force curve jumps up significantly right after actuation, feels perfect — but one thing I do miss from my time trying out lighter switches like the Gateron Browns and Reds is how much less fatiguing it is to actuate the switch. Ideally, then, I’d like to shift the force curve before actuation (at 1.9mm) down uniformly, and leave the back end largely unchanged.
It seems like in theory a dual-stage sprint could do this, so I’ve been looking around at them, But I can’t seem to find very many and I honestly don’t know what to look for. Can someone recommend any?
From the post you linked it actually looks like I might want the opposite, short progressive or complex springs, since I want to minimize the initial force while maximizing the bottom out force? I’ve looked around trying to find medium-heavy progressives or complexes but can’t fine any
Thank you so much! It looks like RNDKBD only has progressives with a 63g bottom out force, which is way too light for me, but I’ll poke around on their website now that I know they exist!
I did find a non-SPRiT progressive spring, that comes in a slightly heavier variant, the “Thick Thock Magic Progressive” springs: Thic Thock Spring V2 - MP Series
Halo True springs are my favorite of the kind you describe, but they can be tiring. I wish there was more variety in the short / fast curve style - but one other I can think of off-hand are NovelKeys’ Cream Arc switches; a variant of Creams that come with a progressive spring. I think SwitchOddities has samples if you want to try them.
Thanks for the info I’ll investigate! And yeah, the halo trues are absolutely the best switch I’ve found so far. Their force curve is almost exactly what I would have drawn if someone had asked me to just take out a sheet of paper and to draw my ideal force curve. It’s just a little bit too heavy in the beginning.
I was looking at the SPRIT complex switches the other day too and same as what you found. No one else had them in stock.
What I like about SPRIT springs from their marketing material is the graphs that they provide comparing the different product lines they have on offer. Not sure how accurate they are and I wish other spring manufacturers showed something similar (or maybe they’re all linear curves?).
Thanks a bunch for this pointer, It looks like these might really work out for me. Is there anywhere I can see the force curve of these springs, or get their spring constant or something, so I can judge what their weight would be at the actuation point and stuff? The TX short 90g spring looks like it might be perfect, since it’s essentially just the same kind of thing as the Halo Trues already have just 10 grams lighter, but I want to do a bit more research.
Good! I think that info will be hard to come by, especially in a specific weight. Depending on shipping cost to you, it may be worth just getting a couple of packs to try vs. hunting too much for it. I feel like down to 70gf could still be heavy enough to get the effect you want without becoming fatiguing. In general, I think short springs can have a cushion-ey feeling.
I picked up 90 gram, 80 gram, and 75 gram Tx short springs. The 90 gram arrived as 85 gram, but I think that’s going to turn out really well because the 80 gram are almost perfect but slightly too light so I think I’ll be using the 85 gram! I’m probably going to use the 75 grams springs for all modifier keys and the keys under my pinky fingers. Thank you so much for the TX shorts rec, they’re not ideal, but I think they’ll do the job pretty well!
