The Keygeek Y2 switch, designed by MZ Studio, again proves to us that Keygeek has no limits when it comes to innovation. The Y2 switches use Keygeek's newest waffle stem tip molding to create an extremely deep sound profile. The stem tip comes with a textured design, which reduces the contact surface area to eliminate any possible clacky or poppy tone. The PA12 housing increases the overall smoothness and further minimizes any scratch sound that might exist, leading to a pure and deep bottom-out sound profile – Unikeys. | MMD Vivian linear switch delivers a satisfying thocky sound profile. The switch features a modified UPE stem that enhances durability. Its top housing is constructed from PA12, while the bottom housing uses modified PUM – Lume Keebs. |
