The Keygeek Crepe linear switch is a unique linear switch that delivers a clean, full-bodied, and satisfyingly clacky typing experience. As Keygeek’s first switch to feature a custom PBT stem, the Crepe introduces improved rigidity and durability while producing the crisp acoustic profile that PBT is known for. The Keygeek Crepe is designed around a carefully balanced material combination that creates a lively yet smooth sound signature: PBT Stem - Naturally crisp and clacky with enhanced rigidity for a more defined bottom-out sound. P4 Blend bottom housing - Adds fullness and depth to the overall typing acoustics. PC top housing – Maintains an ultra-smooth keypress while keeping the sound clean and consistent. Together, these materials create a bright and full-sounding typing experience that feels responsive, refined, and enjoyable during long typing sessions. The Crepe switch also introduces Keygeek’s updated top housing structure. The stem-to-top housing contact point now uses a stripe-shaped surface design, helping improve top-out acoustics and creating a cleaner, more controlled sound signature. Keygeek Crepe comes factory lubed using Keygeek’s newest lubrication process. Lube is applied precisely to maintain a buttery smooth feel without excessive oiliness, preserving both switch smoothness and sound clarity straight out of the box – Unikeys. | HMX Cthulhu is here! Designed in collaboration with SULAB for enthusiasts who love loud, sharp, and clacky typing, it delivers an ultra-clacky, bright sound that stands out on any build. Featuring a smooth M1 modified POM stem and a high-fiberglass P7 bottom housing — the highest fibreglass content HMX has used to date – SerpentKeys. |
