XLLAB X Haimu Rock tactile switch is another Haimu tactile switch that comes with a metal insert in its stem. The metal insert complements the tactile bump as it further solidifies the bottom-out sound and feel. With such strongly expressed tactile sensation, sound, and feel, "Rock" is probably their most suitable name.
