So as I mentioned in another thread I've been kind of disappointed by Hako switches, preferring the old Halo design. My main issue is the lack of any real tactile feedback as to where the actuation point is. Halo switches had a small but perceptible post-actuation bump that let my fingers know they had gone far enough but Hako switches are too smooth and since I can't feel the actuation point I press too far and they end just feeling really heavy. Hako Clears have a pre-actuation bump but it happens so early it feels more confusing than anything. You can completely clear the bump and yet find you didn't actually go far enough to actuate.
So I thought what if I put some of those special springs in a Kailh Box White? The spring replacement options for box switches have been pretty limited but fortunately Hako switches are also box switches so the spring swap can be done without any issue. And when placed in a Box White you still have that distinctive sharp tactility and click from the clickbar that makes the actuation point unmistakable but it's combined with the non-linear heavy Hako spring that discourages bottoming out by ramping up the force curve post actuation.
It is honestly a pretty great combo. If you compare it to something like a Box Pale Blue--which has a heavier spring than Box White but one that follows a more conventional linear force curve--they feel pretty similar up to the click but post-click the Hako spring is clearly much stiffer.
Now I really want to try this with Hako True as well, but unfortunately the ony Hako Trues I have right now are in my NightFox, not loose, and I'm not quite willing to take it apart yet. I have enough loose Box Whites and Hako Clears to deck out a whole board though...
