The Keygeek Cera and Unikeys x BSUN Udon switches are both standard MX mechanical switches of the linear breed. They both feature 48 g actuation, 55 g bottom-out force, 2 mm pre-travel, however, they come with different top housing (L4 POM vs PC), bottom housing (L4 POM vs PA66 + 30% fiberglass), stem material (modified POM (with ceramic powder) vs Y3X), stem shape (standard (flat stem tip) vs standard), spring (20 mm single-stage KOS vs 22 mm single-stage nickel-plated), total travel (3.70 mm vs 3.60 mm). That said, they are not too similar. Let's check out this side-by-side specs rundawn with details, availability -- and even current prices -- to figure out which one fits you the best!

Comments on Keygeek Cera switches | Comments on Unikeys x BSUN Udon switches |
The Keygeek Cera linear switch is Keygeek's another full POM switch. Unlike POMkin, Cera has a flat pole tip for a more clacky and crispy sound profile. Designer Gearpod also commissioned a new housing mold for them. Because full POM switches tend to have more surface friction, the sizes of the top housing opening and bottom housing stem hole have been adjusted to make sure the stem wobble is minimal while eliminating the sluggish feeling caused by the syringe effect. Material-wise, the POM stem was modified with ceramic powder added to increase its hardness and lower POM's surface friction coefficient as much as possible. The Cera switch also comes with a different factory lubrication method from previous Keygeek switches: The stem is lubed with dry film. The top housing is dry to get rid of the oily feeling – Unikeys. | The Unikeys Udon linear switch is our attempt at trying to create a clacky BSUN switch that is not thin-sounding. The stem material, Y3X, is the same as the Jade Rosales switches; It can be considered an improved LY or Y3 material, and Y3X is slightly softer than LY but much smoother than both LY and Y3. We chose to pair it with a modified PA66 bottom housing to create a full but clacky-sounding bottom out. The PC top housing gives them a clean and sharp top-out sound. Overall, these will be one of the more clacky new BSUN switches in our collection. In order to prevent the lube pooling issues, we chose to only lube the stem sliders and legs with a very thin coat of 205g0. Springs are lubed with dry film – Unikeys. |
