How do these compare with the Jade Kailh Box switches?
Jul 31, 2021
Kailh Box Jades are clicky switches, while these are linear so the comparison is moot.

So a box variant of the Everglide Aqua Kings?
Aug 3, 2021
No, the housing is full PC, but the stem is nylon, so it's not a full PC switch like the Aqua Kings

Do these become clicky over time as well like all other box type switches?
I've never heard of a box switch "becoming" clicky over time. Sure, a bunch of the box switches are designed with a click bar, but I'm not aware of any instances of a linear/tactile box switch developing a click. Just bought a kit of Box Creams for a board though so maybe I'll be proven wrong.

It looks like those were tactile switches that already had the nub inside that creates a bump sensation, and the lube on those wore out, making them louder than before. Linear switches wouldn't have this nub to begin with.

Joey_SpacebarBox Royals are notorious for becoming more clicky than tactile over time. The "all other box type switches" is total nonsense though.
Late answer since these are coming around again; For these (and other linear BOXes), the answer is no. The reason is that the stem rail that interacts with the contact pusher is a linear ramp - the BOX switches that start to click over time are the tactile ones with bumps on that ramp / leg. The lube on the little pusher displaces or thins over time, and at a certain point it starts to tick as it crests the stem bump. This unfortunately includes the silent ones - however, you can re-grease the part if you really want to.

I've seen Kailh's video where it's linear (Jellyfish Y) and it's clicky (Jellyfish X). Are there two different switches? Or is it the same switch but modified through disassembly like Zeal's Clickiez?
They are sold as different options, and not all vendors have both. The version here on Drop is the linear one - the clicky one available elsewhere is identically the same switch, just with the addition of the click-bar torsion spring. By the same token, you can remove that spring from the clicky ones to convert them into linear and back - but if you buy the linear ones, they won't come with the click-bars. That said, you can take click-bars from other click-bar switches and use them - those from any Kailh BOX or Kailh Speed switch (that have them to begin with) should work in the Jellyfish switches. (This includes the thicc ones from Navies and Jades.) They just drop into place, and are held in with light friction - pretty easy to install and remove with tweezers.
