HMX
Hmx Pebble
HMX is a relatively new switch manufacturer known for excellent factory lubrication. The Pebble linear switch, also known as the Gravel switch, is unique in its housing materials, as PA66 is a specially formulated nylon blend that produces a satisfying bottom-out sound. The materials were specifically chosen to achieve a lower-pitch clack, closer to a thocky sound profile. The added factory lube gives it smoothness and further sound dampening, and the switches are pre-lubed from the factory.
