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.
✨ The Hyacinth V2 Solution: HMX ultra-precise L3 molds, extended POM stem pole for deep clacks, 22mm Korean springs, and micro-thin factory lubrication.
Ultra-Tight Mold Tolerances
HMX Precision Molds & Extended POM Stem Pole
Manufacturing Upgrade (Feature)
Switched from KTT to HMX manufacturing, utilizing HMX's ultra-precise L3 molds and an extended POM stem pole.
Engineering Advantage (Advantage)
Eliminates stem wobble almost entirely while keeping housing tightness firm without pinching or binding the stem travel.
What It Means For You (Benefit)
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
Material Synergy (Feature)
Combines a high-clarity Polycarbonate (PC) top housing with a dense Nylon bottom housing and self-lubricating POM stem.
Acoustic Advantage (Advantage)
PC amplifies crisp high frequencies upon return, while Nylon deepens the impact tone upon bottom-out for a balanced acoustic profile.
What It Means For You (Benefit)
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
Precision Tuning (Feature)
Equipped with a 22mm single-stage Korean spring offering 45g actuation and 52g bottom-out, pre-lubed at the HMX factory.
Performance Advantage (Advantage)
Micro-lubrication on sliders and legs eliminates spring ping immediately out of the box with zero lube pooling risk.
What It Means For You (Benefit)
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."
— @ClackEnthusiast, Verified Buyer
★★★★★
"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."
— @KeebModder_Dan, Software Engineer
★★★★★
"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."

Genuine HMX manufactured Hyacinth V2 switches with precision L3 molds.Frequently Asked Questions
The biggest upgrade is changing manufacturers from KTT to HMX. HMX uses ultra-precise L3 molds resulting in significantly tighter tolerances, minimal stem wobble, zero housing flex, and a cleaner, deeper acoustic "clack" profile.
No! HMX factory lubrication is regarded as some of the finest in the industry. The lube is applied consistently across the stem rails and spring, making them ready to install straight out of the box.
Yes. These switches feature a 5-pin PCB mount layout for maximum stability. If your keyboard PCB only supports 3-pin switches, you can easily clip off the two extra plastic alignment pins using flush cutters.
Thanks to the extended stem pole, PC top housing, and Nylon bottom housing, Hyacinth V2 produces a distinct, crisp, and resonant deep "clack" rather than a muted thock.
