HMX
Hmx Hydra







The HMX Hydra tactile switch is designed by XLLAB and features a big, almost D-shaped tactile bump similar to Retro J. It is an attempt to replicate the classic Gateron Type R D-shaped bump, combined with HMX's signature clacky sound profile and excellent stem wobble control. Thanks to the P2 bottom housing, Hydra is one of the clackiest HMX tactile switches so far. Factory lubed: a very thin coat of 205g0 on the stem legs and sliders, with the spring and leaf lubed with dry film.
