Comments on Keygeek M3 switches | Comments on Unikeys x BSUN Udon switches |
M3 is the first Keygeek switch that uses the LY material. LY itself is not an actual raw material but a made-up code name for certain material blends. In Keygeek's case, LY stands for a blend of POM. Paired with the P5 bottom housing, which is also super rigid, the M3 switch has a clacky and even metallic sound profile – Unikeys. The Keygeek M3 are MX‑style linear switches and the first model in the series to use an LY stem – a special POM blend that creates a bright, clacky sound profile. Combined with the very firm P5 bottom housing, the result is a switch that stands out clearly from the softer, more “creamy” Keygeek variants and offers a crisp, resonant typing feel – MonacoKeys. | 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. |
