The HMX Radio Wave Linear Switch combines an LY stem, PA12 top housing, and Nylon P3 bottom housing to deliver an exceptionally smooth and balanced typing experience. The low-friction LY stem provides effortless key travel, while the PA12 top housing softens the top-out and helps reduce unwanted resonance for a cleaner sound. The Nylon P3 bottom housing adds warmth and depth, producing a rich, bassy bottom-out with a satisfying acoustic profile. Paired with a 22mm single-stage spring for a consistent, responsive feel with slightly cushioned impact, the Radio Wave is an excellent choice for those seeking a smooth linear switch with deep, creamy acoustics and a comfortable typing experience.
