HMX Sillyworks Hyacinth V2 Linear Switch

HMX | Sillyworks Hyacinth V2 Switch
The Ultimate Clacky Linear Upgrade: HMX Ultra-Tight Mold Tolerances, Extended POM Stem & Resonant Deep Clack.
Following the legendary success of Hyacinth V1, Sillyworks partnered with premier manufacturer HMX to create the long-awaited Hyacinth V2.
Engineered with an extended POM stem pole, precision PC top housing, and Nylon bottom housing, Hyacinth V2 delivers an insanely crisp top-out sound and a signature deep, poppy "clack" in every keystroke. Paired with a 22mm single-stage Korean spring and HMX's world-class factory lubrication, experience a frictionless, silk-smooth stroke with virtually zero stem wobble.
Why Hyacinth V2 Sets the Gold Standard for Clacky Linears
Upgrade your mechanical keyboard without settling for stem wobble, scratchy travel, or hollow acoustic profiles.
Stem Wobble & Loose Tolerances
Conventional switches often suffer from loose housing fits and stem wobble, ruining keycap stability during fast typing.
Muted & Hollow Sound Profiles
Standard stems fail to produce a clean bottom-out sound, resulting in flat, muddy, or uninspiring typing audio.
Scratchy Unlubed Keypresses
Generic factory lubing leaves spring ping and rail scratchiness, forcing builders to spend hours hand-lubing each switch.
Ultra-Tight Mold Tolerances
HMX Precision Molds & Extended POM Stem Pole
Switched from KTT to HMX manufacturing, utilizing HMX's ultra-precise L3 molds and an extended POM stem pole.
Eliminates stem wobble almost entirely while keeping housing tightness firm without pinching or binding the stem travel.
Enjoy rock-solid keycap stability and a signature, resonant top-out & bottom-out "clack" that transforms typing into pure auditory ASMR.
Resonant Acoustics
Polycarbonate Top & Acoustic Nylon Bottom Housing
Combines a high-clarity Polycarbonate (PC) top housing with a dense Nylon bottom housing and self-lubricating POM stem.
PC amplifies crisp high frequencies upon return, while Nylon deepens the impact tone upon bottom-out for a balanced acoustic profile.
Deliver a rich, creamy, and polished deep-clack sound profile across any custom aluminum, PC, or FR4 keyboard plate build.
Snappy & Frictionless
22mm Korean Extended Spring & Factory Lubrication
Equipped with a 22mm single-stage Korean spring offering 45g actuation and 52g bottom-out, pre-lubed at the HMX factory.
Micro-lubrication on sliders and legs eliminates spring ping immediately out of the box with zero lube pooling risk.
Skip manual lubing entirely. Enjoy an energetic, snappy return push that cradles your fingers during long coding or gaming sessions.

Verified Customer & Builder Reviews
"The HMX mold upgrade is night and day!"
"I loved Hyacinth V1, but V2 manufactured by HMX takes it to a whole new level. Stem wobble is virtually nonexistent and the clack sound on my FR4 plate is deep, crisp, and incredibly loud."
"Smooth as silk right out of the box!"
"Didn't even bother opening them to hand lube. HMX's factory lubrication is chef's kiss level. The 22mm spring gives an amazing energetic pop on the rebound. 10/10 recommend."
"My favorite linear switch of the year!"
"The 1.9mm pre-travel and 3.5mm total travel feels compact, responsive, and ultra-snappy. Best clacky sound profile I've heard on my custom PC gasket mount board."
