Hmx Quantum






Designed by JKDK and manufactured by HMX, Quantum is a factory-lubed, five-pin linear switch with a crisp and clacky sound profile. HMX's third-generation mold and lubrication process are designed for a balanced feel and sound, ready to use out of the box. Fine glitter in the translucent modified-PA12 top housing catches the light above a milky N4 bottom housing. A modified-POM stem, 22 mm single-stage spring, and light guide complete the switch. The product photos show a sample; the light guide is specified for the production version. Such materials not only make the Quantum switch exceptionally beautiful; the PA12 top housing and modified POM stem guarantee smoothness, while the N4-strengthened nylon bottom housing gives it a clacky and clean bottom-out sound. Similar to other clacky HMX switches manufactured with the third generation molds, the Quantum switch is a great option for clack lovers
