Kailh Silent Series Flagship
BOX Deep Sea Hush Pro Tactile (Whale)
The Ultimate Symphony of Abyss-Level Silence and Solid Mechanical Confirmation.
Are you still tolerating the clatter of mechanical keys or the cheap, mushy feel of typical budget silent switches? Kailh proudly introduces the flagship evolution of our silent lineup—the "BOX Deep Sea Hush Pro Tactile," also known as the Whale Switch.
Engineered for professionals who demand a "zero-interference" focus and gamers who crave definitive tactile feedback. It combines an upgraded high-polymer dampening system with the legendary BOX sealed structure to aggressively suppress noise below 35dB. Tuned with a refined 60gf tactile bump, it completely eradicates the "muddy" feel of traditional silent switches, delivering a pure, crisp typing experience as serene as the deep sea.

Core Advantages: Reshaping Your Silent Input Perception
We know you love the satisfying "bump" of tactiles but demand absolute silence. The Whale Pro is built to balance "zero noise" with "solid mechanical confirmation."
The Problem: Loud & Disruptive
Standard tactile switches (like Browns/Blues) clack loudly, interrupting focus. Typical silent switches often have incomplete noise cancellation, leaving behind annoying friction sounds.
The Problem: Mushy & Vague
To mask sound, many switches use soft pads that make bottoming-out feel like "stepping in mud," leading to a weak rebound and vague, unsatisfying tactile feedback.
The Problem: Dim & Unreliable
Standard housings block your RGB lighting, while ordinary housings allow dust to enter, leading to failure or annoying double-clicks over time.
✨ BOX Deep Sea Hush Pro (Whale): The ultimate solution offering ≤35dB polymer silence, a crisp 60gf tactile bump, and a legendary 100M cycle BOX sealed structure.
Say Goodbye to Bothersome Clack
≤35dB Abyss Silence via Precision Dampening
Traditional Issue
Standard tactile switches emit sharp clacks that disrupt thought flow. Typical budget silent switches suffer from residual friction noise and incomplete dampening.
The Whale Pro Advantage
Features a newly designed dual-silicone silencing architecture, including thickened sidewall dampeners and specialized high-polymer buffer pads for full-travel coverage.
The Benefit
Make your keyboard "invisible" to ears. This bi-directional design absorbs over 95% of physical impact noise. Even in a silent library or bedroom at night, you hear only a faint, pure "thud" (≤35dB), restoring total peace.
Say Goodbye to Mushy Silence
60gf Sharp Confirmation & Snappy Rebound
Traditional Issue
Most silent switches compromise by feeling soft and vague, almost like "stepping in mud." The weak rebound ruins the typing rhythm and causes significant finger fatigue.
The Whale Pro Advantage
Meticulously tuned with a 60gf tactile bump at 1.3mm, paired with an automated factory lube and a 19.5mm extended snappy spring.
The Benefit
Every keystroke yields a definitive confirmation. The long spring provides strong initial support and a snappy return, completely eliminating the "muddy" feel. Experience a solid, "walking on thin ice" sensation that enhances your rhythm and prevents typos.
Say Goodbye to Dim RGB & Decay
BOX Sealed Safety & 100M Cycle Durability
Traditional Issue
Solid switch housings block RGB light, and standard housings allow dust to enter, leading to premature failure or annoying double-click issues during long-term use.
The Whale Pro Advantage
Features an independent high-transparency Light Guide Pillar to focus RGB light, alongside the signature BOX sealed-chamber technology for core components.
The Benefit
A switch that lasts a lifetime. The BOX structure provides IP56-rated water and dust resistance. The Light Guide Pillar boosts RGB brightness by over 40%, ensuring your setup shines with vibrant, even lighting for a certified 100-million cycle life.

Most silent tactiles feel "mushy" because they focus too much on soft dampening. The Whale switch uses a higher-density polymer dampener and a deliberate 60gf tactile bump. This creates a crisp, definitive confirmation—similar to "stepping on thin ice"—while staying almost completely mute. It solves the "sponge" problem of silent switches entirely.
No. The Whale series is precision-lubricated at the factory on friction points like the stem rails and springs using professional automated equipment. They reach a peak buttery state straight out of the box, ready to be installed immediately without any extra work.
35dB is roughly equivalent to background noise in a quiet library or a faint whisper. It effectively absorbs both the bottom-out impact and the upstroke collision, making it perfect for office environments where focus is key or shared bedrooms late at night.
Significantly. Ordinary switch housings often block bottom-mounted LED light. The independent Light Guide Pillar acts like a fiber optic channel, focusing and diffusing the light directly to the keycap, boosting overall RGB brightness by over 40% while ensuring zero dark zones and more accurate colors.
Yes! Whale Pro uses a standard 3-pin design and is compatible with almost all MX-style hot-swap mechanical keyboards on the market (including brands like Lofree, IQUNIX, Keychron, and NuPhy). As long as your keyboard supports standard Cherry-cross style stems, it will fit perfectly.
