HMX
Sillyworks X Hmx Sonja





The HMX Sonja linear switch, designed by Sillyworks, is a new HMX rail bottom-out switch. Unlike Snow Crash switches, Sonja uses a housing mold customized by Sillyworks, with an intentionally rough top housing texture for a satisfying scratchy feel. It is lubed using the same method as Snow Crash: only the leaves and springs are factory-lubed, with leaves getting a thin coat of 205g0/105g0 mix and springs getting dry-film lube, while the stem and housings remain dry.
