This brand new Kailh Deep Sea silent mechanical keyboard switch is something special. Kailh is a close partner and has been working on this Master iteration for some time. In the past Masters had minor quirks that needed ironing out. This may be, at present, the highest quality and most advanced silent linear switch that Kailh manufactures.
Introducing the Kailh Deep Sea Ultra-Silent Box Master V3.
Highly Limited stock
Keycap Compatible LED Window
The older Linear Jellyfish Master has a slightly miss-aligned operating and reset-point, a nylon stem that can turn scratchy over time. The V2 improved on the stem but didn't align the operating and reset-point fully. V3 improves upon past experiments with even tighter tolerances. There is a fully-sealed circular white POM stem with Nylon Housing (BOX) and an overlapped operating and reset path.
The Box Masters V2 series is still relatively new and hasn't fully hit stores yet. We didn't like the V2 as their viewing window for LEDs could jam on certain keycaps, so we declined to feature them. V3 has an improved tapered LED window to prevent keycap compatibility issues seen in previous Masters.
An improvement on the BOX Silent series, the V3 Master design mitigates both downstroke and upstroke noise. We take the same circular stem dust wall design from our popular BOX Silent switches from Kailh, upgraded the stem material, and apply enhanced sound absorption using novel TPE/Stainless Steel blends. Unlike the BOX Silent switches the stem has no integrated padding, increasing compatibility with other stems for franken-switches. Noise levels from the Kailh lab measured an exceptionally silent, ≤ 35db*.
The V3 retooling comes with even higher tolerances (including production QA). Switch quality is significantly upgraded, full copper alloy plates with composite gold contacts.
BOX Housing rated at IP54 (except terminals). The switch uses a 3-pin bottom housing to ensure high plug-and-playability.
These switches have a 100 Million Activation Life Expectancy and are IP54 - except terminals.
These switches are packed in a protective tin and include a switch puller.

Due to the high quality of material and increased design complexity, a rigorous lab testing process was instilled. Weatherization: sub-zero temperature of -20C for 48 hours. Heat-stressed at 70c for 48 hours.
Temperature Fluctuations: five repeated cycles of temperature fluctuating between 20c, -20c, 20c, 70c (1 hour each)
Humidity: 48 hours, with 90-95% relative humidity at 60c.
In the spirit of SwitchCaptain and the Deep Blue naming of this switch, the Kailh lab also sprayed the switches with salt water for 12 hours straight at 35c. No corrosion, no cracks, no exposed base plates.
For those DIYers soldering the switch, we ensured no abnormalities at soldering temperatures of 260c were present at 3-second intervals. The switch can handle 350c soldering temperature at 3-second intervals and will ensure a 95% surface area solder immersion.
*Sound Testing Specifications
Background Noise: 10db Max
Mechanical Push Lever: Activate product 3 times per second for 10 seconds
Distance: 10cm max from the switch
Dongguan Kaihua Electronics Co., known in the USA as Kailh, is a manufacturer of top-of-the-line mechanical keyboard switches and is famous in particular for their box switches.
All BOX Silent Brown switches are ordered directly from Kailh, tested in the US by SwitchCaptain, and packaged in sets.
What is the SwitchCaptain Authentication program?
We are keyboard and mice enthusiasts ourselves, we have spent hours (perhaps days, okay fine, weeks) trying to find particular keycaps, switches, lubricants, and more. Too often we stumble across knock-off products, poor quality components (that can do real damage), and sometimes even stores passing non-genuine products as the real thing! Enough is enough. So we got together and decided on a plan moving forward to stop fake products from hurting all the different folks involved.
The SwitchCaptain Authentication program includes a holographic seal on every item we sell, each seal has a unique code that lets you verify your product came from the original brand.
We want you to know that if you buy a product from us that what you get is real.
Let us be clear:
- All branded products we sell are bought from the manufacturer directly, we do not try to save a buck and purchase from a supplier (which we find super suspicious in the first place). If a manufacturer won't sell to us direct we will not have it in the store. This includes big names as well as up-and-comers.
- This also means that manufacturers ship directly to us, we inspect for quality, package them in sealed bags (so they cannot be tainted), code them into our authentication database, and ship it to the customer (that's you!). We do not allow 'middle-persons' to broker any product, as this opens up an opportunity for manipulation.
- Any product from SwitchCaptain without an authentication sticker is counterfeit or repurposed without authorization. Even our refurbished products are authorized.
- We require all brands to provide us with proof of any certifications they say they have. The onus is still on them of course. If a manufacturer cannot produce for example their RoHS (Restriction of Hazardous Substances Directive) when they are supposed to be able to, we will not work with them. While we do not know of all licenses, permits, and certifications, we try our best to keep an eye out.
