Kailh Black Iris Linear Silent Switch
The Stealth Speed Demon: 25dB Dual-Silicone Dampening Meets an Ultra-Rapid 1.8mm Total Travel.
Are you tired of sluggish low-profile switches that clatter loudly in quiet offices or bottom out in mushy ambiguity during clutch fighting-game combos? Kailh redefines low-profile mechanics with the exclusive "Black Iris" (墨鸢/黑鸢 Mini) switch.
Engineered on the acclaimed Falcon/Raptor low-profile tooling, it integrates precision dual-side silicone sound-absorption pads alongside an aggressive 1.2mm fast actuation and 1.8mm condensed bottom-out travel. Delivering a balanced 40gf operating force and a 15mm stainless steel recoil spring, it produces whisper-quiet 25dB acoustics while delivering instantaneous input resets for keyboards and competitive leverless fightsticks alike.

Core Advantages: Engineering The Ultimate Low-Profile Switch
Standard low-profile switches force compromises between sharp plastic clatter, long 3.0mm bottom-out delays, and mushy return dampening. The Kailh Black Iris eliminates all three.
The Problem: Clattering Office Distraction
Conventional low-profile switches lack internal dampeners. The shallow housing accentuates high-frequency plastic clacks on bottom-out and top-out, causing friction in open workspaces.
The Problem: Sluggish 3.0mm Reset Delay
Standard low-profile switches utilize 2.8mm to 3.0mm travel. In fast-paced rhythm games or competitive fighting games (Hitbox controllers), excess travel wastes critical milliseconds on rebound.
The Problem: Mushy Bottom-Out Fatigue
Poorly implemented silent pads make the keystroke feel like stepping in mud. They deaden sound at the cost of crisp bottom-out certainty, creating hand fatigue during long typing marathons.
⚡ The Kailh Black Iris Solution: Dual-rail precision silicone silencing down to ≤25dB, an ultra-compressed 1.8mm total travel, and a self-lubricating POM core for crisp, rapid-fire resets.
Acoustic Masterclass
Dual-Rail Silicone Rings for ≤25dB Whisper Silence
The Solution
Constructed with dual-side integrated silicone dampening pads precision-embedded along both guide rails of the POM stem, intercepting both downstroke bottom-out and upstroke top-out impact forces.
The Benefit
Enjoy near-silent operation measured at ≤25dB. Harsh plastic collision noise is transformed into a subtle, velvety whisper, allowing uninhibited high-speed typing in libraries, quiet bedrooms, or shared office bullpens without drawing unwanted attention.
Lightning Physical Advantage
1.2mm Fast Conduction & 1.8mm Total Short Travel
The Solution
Dramatically reduces traditional 2.8mm - 3.0mm low-profile key travel down to an ultra-condensed 1.8mm bottom-out, registering commands at a hair-trigger 1.2mm pre-travel point.
The Benefit
Unlock unmatched tactile responsiveness. By stopping the stroke at 1.8mm, your fingers spend 40% less time bottoming out, leading to instantaneous mechanical resets. Whether executing quarter-circle special moves on a Hitbox arcade controller or typing at 130+ WPM, input lag is virtually erased.
Endurance Engineering
Self-Lubricating POM Core & Universal Hot-Swap Mount
The Solution
Forged with a wear-resistant POM stem and solid POM bottom base, paired with a 15mm high-grade stainless steel recoil spring and high-grade copper alloy contact leaves.
The Benefit
Enjoy enduring buttery smoothness that gets slicker the more you play. Engineered for broad low-profile platform hot-swap compatibility (including Lofree Flow / Edge low-profile architectures and specialized leverless fight controllers), guaranteed for over 50 million flawless actuations.

"Installed on my leverless Hitbox. Game changer."
"The 1.8mm bottom-out distance makes a massive difference in Street Fighter 6. My double-taps and drive rushes come out instantly because you don't waste time plunging down 3mm. And the 25dB silence means I can play in the living room late at night without waking anyone."

★★★★★
"The quietest low-profile switch I've ever typed on."
"I put these into my slim wireless board for office meetings. The silence is genuine—not that fake clack dampened with grease, but actual internal silicone rings. 40g actuation feels effortless during 8-hour document editing sessions."
— @SilentTyper, Remote Product Manager
★★★★★
"No mushiness despite being silent."
"Most silent switches feel like pressing into wet dough. Because the Black Iris stops hard at 1.8mm with firm silicone rails, the bottom-out is crisp and definite. The POM-on-POM glide feels buttery right out of the packaging."

No, this is a dedicated Low-Profile mechanical switch built on the Kailh Mini / Falcon low-profile platform. It is engineered specifically for low-profile mechanical keyboards (such as the Lofree Flow series, Lofree Edge, and Kailh low-profile compatible PCBs) as well as leverless arcade controllers (Hitbox / Flatbox). It will not fit into full-height standard Cherry MX-style PCB switch sockets.
Standard low-profile switches have around 2.8mm to 3.0mm of travel, while traditional mechanical switches travel 4.0mm. By condensing total travel down to 1.8mm with a 1.2mm actuation point, the switch bottoms out almost immediately after actuation. This allows the 15mm spring to push the key back up much sooner, enabling significantly faster double-taps, lightning-fast fighting game inputs, and effortless high-speed touch typing with minimal finger fatigue.
Unlike typical switches where rigid plastic parts slam directly into each other at the bottom and top of the stroke, the Black Iris embeds specialized silicone dampening rings on both side rails of the POM stem. These micro-cushions absorb the impact kinetic energy before plastic-on-plastic collision can occur, muffling operation noise to an ultra-low 25 decibels—comparable to rustling leaves.
In competitive fighting games like Tekken, Street Fighter, and Guilty Gear, execution speed is paramount. The combination of 1.2mm hair-trigger actuation, 1.8mm bottom-out stop, and 40gf light actuation gives players near-instantaneous command verification and zero return lag for directional inputs. The 25dB silence is an added bonus, eliminating the distracting clicky noise during intense tournament matches or late-night practice.
No manual lubing is required. The switch slider and base housing are made from premium self-lubricating POM material and come factory-lubricated with high-precision automated application on the guide rails and contact leaf. It glides smoothly right out of the box with zero scratchiness.
