The HMX Sonja linear switch designed by Siliworks (Previously Sillyworks) is a new HMX rail bottom-out switch. Different from the snow crash switches, the housing mold Sonja switches use is customized by Silliworks; The top housing comes with an intentional rough texture to create a satisfying scratchy feel. Factory lubing: Sonja switches are lubed using the same method as Snow Crash switches; only the leaves and springs are factory-lubed. Leaves are lubed with a thin coat of 205g0 and 105g0 mix, and springs are lubed with dry-film. The stem, bottom housing, and top housing are all dry. 1 quantity = 10 switches  Switch Type: Linear Rail Bottom-out Designer: Silliworks Manufacturer: HMX Stem material: POM  Top Housing: PA66 (With texture for scratchiness) Bottom Housing: PA66 Operating Force: 45±2g Bottom-out Force: 52±2g Pre-travel: 2.0mm Total Travel: 3.9±0.2mm Spring: 22mm KOS single-stage extended Factory Lubed: Yes! mixed GPL105&GPL205 on leaf spring, stem feet, and bottom housing rails.
