The Zealios V2 are a well-regarded switch made by ZealPC in partnership with Gateron, which has come to rival the famous Holy Panda switches. This particular Zealio in my hands is a 62g weighted one, which is the lightest out of the four Zealios weights, those being 62g, 65g, 67g, and a hefty 78g version.
These Zealio switches feature a purple stem which with each weight, has a darker colored stem with the heavier weights sporting the deeper purples.
I bought my Zealios V2 from KDBfans at $1 per switch, which like its brothers, the Tealios, Healios, and the recolors Sakurios & Rosélios, are very expensive compared to other mainstream switches which retail at merely $0.30 per switch. Despite the price, I think the Zealios are what everything who enjoys tactile switches should look into, they have a satisfying tactile bump as well as smooth actuation. I would describe the Zealios V2 as Brown switches on steroids, with the tactile bump being extremely prominent while still maintaining the smoothness I expect out of a comparitive linear switch.
The tactile bump also begins at the top of the switch which makes the tactile bump satisfying while not interupting the flow of general typing. Some may find this as a disadvantage to the Zealios because traditional tactile switches tend to have pre-travel, but the fact that the Zealios starts it bump at the top with no pre-travel is an excellent design, especially with the stem leg design and how it's weighted.
The tactility comes from the way the legs of the stem are angled, ZealPC has crafted the stem leg's design of the Zealios V2 to be angled at such a a way that the contact leaf generates an amazingly assertive tactile bump. The meticulous convex curve in the stem is the reason the tactile bump is so satisfying, and is ultimately the reason I see the Zealios as the ultimate tactile switch.
I lubed my Zealios with Tribosys 3204 on the housing sliders, center pole, as well as the top and bottom of the spring. As for the stem, I lubed every part of the stem, which means the sliders, front, back, bottom of the sliders, and even the legs.
Even with the stem legs lubed, it is still one of the most tactile switches I have ever used, and it's a testament to the excellent design of the stem, and particularly the legs. As I mentioned before, the legs design is what gives the Zealios their amazing tactile bump, and it's what makes the switch great, even lubed.
The switch is my absolute favorite tactile switch, despite the price, and everyone who prefers tactile switches should experience a Zealio switch for themselves.
