Hmx Tt Red S Light





HMX TT Red S is a light tactile switch designed by TT Lab and manufactured by HMX, built around a small bump tactile character with a crisp, responsive bump and clean, controlled sound. Refined factory lubrication supports a smooth press and noise control. Its hybrid mold uses an L2 bottom housing with L3 molds for the stem and top housing, pairing a POM stem with PA12 top and PA66 bottom housing for a balanced tactile feel. Stem legs and sliders get a thin coat of 205g0; the spring and leaf are dry-film lubed, while other areas stay dry to keep the sound clean.
