The Roller V2 Linear Switches from KBDfans were designed with the goal of perfecting typing feel and reliability for demanding keyboard enthusiasts. With targeted improvements in four key areas, they set new standards for linear switches: Optimized dimensions prevent interference with custom keycaps and ensure seamless integration into a wide range of setups. The consolidated structure simplifies assembly and eliminates issues caused by misaligned rivets, which could lead to blockages in the previous version. Local adjustments to the spring design reduce unwanted noise and deliver a clearer, more pleasant typing experience. An additional light guide enhances LED transmission and provides even illumination—perfect for RGB setups – monacokeys. | HMX Snow Crash switch, designed by Keebscape, is the first ever rail bottom-out HMX switch. It has a full 4mm total travel, traditional PA66 housing and POM stem, and an effortless but clean color. Unlike the traditional HMX switches we know of, the Snow Crash switches don't have a super loud and clacky bottom-out sound since they bottom out on stem rails. They still have that extremely tight stem and near-to-zero stem wobble, but they don't suffer from the so-called syringe effect. The reason is that the stem pole does not go deep into the stem hole so less friction and resistance are created. They are super smooth although they are made with more traditional PA66 and POM, and this is all attributed to HMX's precise molding and factory lubrication – Unikeys. |
