Tired of the muffled sound of dustproof stems?
Dustproof Stems Sound Dull
Traditional dustproof wall stems are stable, but they sacrifice crisp bottom‑out sound, making each keystroke feel underwhelming.
HiFi Seekers Left Wanting
You want smoothness paired with concentrated, pleasing acoustics—most switches fail to deliver both.
Lackluster RGB
Basic light guides scatter illumination, failing to do justice to your carefully chosen keycaps and case.
🌙 Luna Switch – Born for HiFi Typing — The cross‑stem BOX structure unlocks crisp, focused acoustics; the upper‑stem stabilization platform eliminates wobble; the POK+POM self‑lubricating combo gets smoother with use; the diamond‑cut light guide delivers stunning RGB diffusion.
Why Luna Is the Ultimate HiFi Linear
🎵 Cross Stem · HiFi Acoustic Design
Cross Stem BOX — Unleash Pure HiFi Sound
Feature The upgraded cross stem replaces traditional dustproof wall stems while retaining BOX durability, blending MX‑style acoustic optimization. The stem bottoms out centrally, softening top‑housing impact while releasing chamber space for a crisper, louder sound.
Advantage Compared to wall stems, the cross stem delivers more focused, pleasing bottom‑out tones—rich high‑frequency detail without muddy lows. The return sound is smooth, with an open soundstage.
Benefit Enjoy an immersive “HiFi typing” experience—every keystroke flows like moonlight, with concentrated, layered acoustics that turn typing into an auditory pleasure.
Evidence Kailh acoustic lab tests show the cross‑stem BOX structure improves bottom‑out clarity by up to 35% compared to wall stems. Users say “the sound is like a finely tuned instrument.”
🔒 Upper Stem Stabilization
🧈 POK Stem + POM Housing
✨ Self-Lubricating, Gets Smoother
⚡ 45gf Light Actuation
🛡️ Ultimate Stability, Silky Smooth
Stabilization Platform + Self-Lubricating Materials — Stability and Smoothness United
Feature The upper‑stem stabilization platform increases contact area, dramatically reducing stem wobble. The POK stem paired with POM top and bottom housings features self‑lubricating properties with an extremely low coefficient of friction.
Advantage The stabilization platform minimizes wobble even on plateless keyboards. The POK+POM combination ensures buttery smoothness from the first press to millions of cycles later—no additional lubing required.
Benefit Consistent feel, precise control, and zero keycap rattle—perfect for intense gaming or long writing sessions.
Evidence Kailh internal tests show the stabilization platform reduces stem wobble by 62%. After 8 million actuations, friction increase is only 2%—virtually negligible.
🔒 Gold-Plated Contacts · Diamond-Cut Light Guide · 80M Life
Superior reliability, stunning illumination, built to last✨ Reliability Meets Aesthetics
Gold Contacts + Diamond-Cut Light Guide — Peak Stability and Style
Feature Gold‑plated contacts resist oxidation for flawless conductivity; the diamond‑cut light guide with a beveled back enhances light focusing; high‑rebound spring and 80M‑cycle design ensure longevity.
Advantage Gold contacts eliminate double‑clicks or failures caused by corrosion. The diamond‑cut light guide delivers brighter, more uniform RGB illumination with a starburst effect from side angles.
Benefit Long‑term reliability meets jaw‑dropping RGB aesthetics. Luna not only sounds and feels premium but also becomes the visual centerpiece of your desktop.
Evidence Kailh’s gold‑contact technology has been deployed in flagship switches with a failure rate below 0.01%. The community rates its lighting “the most evenly diffused RGB I’ve ever seen.”
🌙 Luna vs. Traditional Dustproof BOX – The Acoustic & Stability Evolution
| Feature | Traditional Dustproof BOX (e.g., BOX Red) | Kailh Luna Switch |
|---|---|---|
| Stem Type | Dustproof wall stem (stability‑focused) | Cross stem + upper stabilization platform (stability & acoustics) |
| Sound Profile | Relatively muffled bottom‑out, weak high frequencies | Central bottom‑out, focused pleasing sound, softer top‑housing impact, crisper chamber release – HiFi acoustics |
| Stem Stability | Wall design offers decent stability | Stabilization platform reduces wobble by 62%, surpassing traditional dustproof designs |
| Light Guide | Basic diffuser, scattered light | Diamond‑cut light guide with beveled back – uniform, bright, starburst effect |
| Contact Technology | Gold‑plated (on select models) | Gold‑plated contacts with superior oxidation resistance, 80M life |
| Material Combination | Mixed POM/POK (varies by model) | POK stem + POM top/bottom housings – self‑lubricating, gets smoother with use |

❓ Frequently Asked Questions
What’s the difference between Luna’s cross stem and traditional dustproof BOX stems?▼
Traditional dustproof (wall) stems prioritize stability but often result in a muffled bottom‑out sound. Luna’s cross stem retains BOX durability while optimizing acoustics through central bottom‑out and chamber tuning, delivering a crisper, more focused, HiFi‑grade sound. Additionally, the upper‑stem stabilization platform actually surpasses traditional dustproof designs in stability.
Is 45gf too light for gaming?▼
45gf is the ideal balance between comfort and responsiveness—lighter than standard Reds (45–50gf) but with a high‑rebound spring for quick reset. It provides snappy actuation for FPS and MOBA games while reducing finger fatigue during long sessions.
Do I need to lube these switches?▼
No. Luna comes factory‑lubed with precision lubrication. The POK stem and POM housing are inherently self‑lubricating, so they’re smooth out of the box. If you prefer a custom sound signature, you can add a thin layer of lube, but it’s not required.
Will the 5‑pin design fit my 3‑pin hot‑swap board?▼
Yes. The two plastic positioning pins can be clipped off with flush cutters to convert to a 3‑pin switch, making it compatible with most 3‑pin hot‑swap PCBs.
How would you describe the sound?▼
The sound is focused, clean, and satisfying—bright highs without harshness, and a controlled low end. The bottom‑out is crisp, and the return is smooth. Many users describe it as “tapping on moon rock” or “like a finely tuned instrument.”
Is the 80M lifespan reliable?▼
Absolutely. Kailh’s gold‑contact technology combined with POM/POK wear‑resistant materials ensures consistent performance well beyond 80 million keystrokes. Lab tests show negligible degradation even after extended use.
