UK Keychron K3v2 Bluetooth RGB Optical Tactile Ultra-slim Aluminium Mac/PC 75% Keyboard - K3-E3-UK

Incorporating the world's first hot-swappable low profile Optical switches to customize per-key typing experience with ease, together with all signature Keychron features.


Connects via Bluetooth and switch among 3 Bluetooth devices easily and 1 wired device. Featuring Bluetooth 5.1 chipset, the K3 offers flawless connectivity whether you're working at home or the office while connecting with your smartphone, laptop and iPad.

  • Connects with up to 3 Bluetooth devices
  • Broadcom Bluetooth 5.1
  • USB Type-C connection

The redesigned low profile switch is 40% slimmer than conventional switches. Together with the streamlined aluminum body makes the K3 one of the thinnest and most lightweight wireless mechanical keyboards in the world.
Compatible for both macOS and Windows. Keychron is one of only a few in the market that comes with a Mac multimedia keys layout for Mac enthusiasts. For Linux users, we also have a dedicated user group to help with the experience.
Two level adjustable rubber feet makes the new K3 more comfortable to type on.

We all have our unique typing preferences, that's why we went the extra mile to make the K3 the world's first hot-swappable low profile Optical switch keyboard. We've implemented an MX-styled stem and stabilizers, and conducted numerous design iterations of the keyboard structure.
You can easily hot-swap every Optical switch to customize your typing experience on the K3 without soldering. *Hot-swappable feature is available for low profile Keychron Optical switch version only.

With the MX-styled stem housing and ultra-low latency, the low profile Keychron Optical switches are crafted for typists or gamers who want to type at lightning speed with a lifespan much greater than industry standards.
*Low profile Keychron Optical switch keyboard is not compatible with any conventional mx style mechanical switch.

  • Light actuated
  • 0.2ms Ultra-low latency
  • 70 million keystroke lifespan

We've spent over a year developing and implementing a MX-styled stem on both the low profile switches for the K3 as well as stabilizers on the big keys like the space bar, left Shift, backspace and Enter key.
It will improve reliability, deliver better typing experiences, and may potentially pave the way for other keycap manufacturers to launch alternative keycaps.

Crafted for productivity, the K3's 75% layout is a compact version of tenkeyless layout. It allows users access to all the essential multimedia and function keys, but with a smaller footprint.

Comes with various RGB backlight settings, you can adjust the keyboard brightness to sync with your mood.

Very nice low profile and relatively compact keyboard. Excellent upgrade from laptop keyboards that I had been using without going to the bulk of the admittedly nice but higher profile switch versions of the Keychron.

Easy for me start touch typing quickly (with my poor technique!!) on a long essay. Sound with the Brown Optical switches is pleasant to my ear and they have a subjectively nice actuation force and bottom out point to them. Good Bluetooth switching between devices with low latency and USB connectivity.

RGB lighting is nice but only switchable via the on-keyboard button, though luckily there are a few options I don't find garish. ABS keycaps so will eventually go shiny and few other officially compatible alternative options if they are not to you liking.

Love the product, and also arrived quicker than anticipated! I kept glancing over at my colleagueon site IT engineer guy at work who was using one of these and really sold me on the product, being 75%, low profile, the hot-swappable keys themselves and simply just the look of the keyboard. The box that it comes in is also really nice!!

this is best replacement for mac keyboard the backlaight on K3 is better than on k8 although the feelings are a bit softer comparing with full-size key-caps and standard size mechanical switches.

keyboardco was wery helpful and proactive.

Upgraded from an Apple Magic Keyboard and can't go back now. The brown switches are useable on calls or in the office without bothering people. Dispatched & delivered on time. Great keyboard, Great service.

Great keyboard, Great support by It is very light and feel good to type. I hope next generations will have more battery life. It lasts about 3-4 days after full day usage.

Love this keyboard. It's an upgrade for me on the K2 I bought last year. Love the lower profile and the quieter keys mean I can use it while on Teams calls for work! RGB lights are fun, only had white on my last keyboard. Now to start experimenting with new key caps and hot swappable switches 🤔
