FelineCubeThe one improvement seems to be the spring, everything else, including the materials is the same essentially. The Ice Candy switches can also have a UHMWPE stem, AFAIK. Aqua Kings use a PC stem instead of a nylon one.
FelineCubeWell, I would like to point out a contradiction with all these statements. This switch is meant to be a collaboration with Chosfox. This switch is based on the Kailh Box Jellyfish but unboxed, Chosfox has two versions of this switch and the Kailh Box Jellyfish. The alternative version of the Kailh Clione Limacina is a tactile switch, meanwhile the alternative version of the Kailh Box Jellyfish Y is the X which is basically a Kailh Box White. Tl;dr: It's a Mx style Kailh Box Jellyfish Y. I would like to try out the switch for the spring, it seems interesting. Chosfox has plenty of collaborations with Kailh in their website at least, and they are slowly being made groupbuys over here. But I haven't seen one of these be successful, because I've tried to buy from each and they keep getting refunded. Anyway, have a nice one. I love Kailh switches, I've tried a variant of the Navy that is a "speed" switch it is very fun. Cheers!
