SUITABLE FOR ALL DEVICES

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 (Check high-res keycap layout and size here). For Linux users, we also have a dedicated user group to help with the experience.

HOT-SWAPPABLE

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 a MX-styled stem and stabilizers, and conducted numerous design iterations of the keyboard structure.

You can easily hot-swap every Optical switch in a few seconds to customize your typing experience on the K3 without soldering. *Hot-swappable feature is available for low profile Keychron Optical switch version only.

MECHANICAL OR OPTICAL?

We’ve overcome different technical challenges to redesign both the low profile Gateron Mechanical switch and low profile Keychron Optical switch in order to elevate the typing experience while enhancing its reliability on the ultra-slim keyboard.

With the MX-styled stem housing and 0.2ms ultra-low latency, the low profile Keychron Optical switches are crafted for typists or gamers who want to type at lightning speed with a 70 million lifespan much greater than industry standards.

*Low profile Keychron Optical switch keyboard is not compatible with any conventional mx style mechanical switch.

ALTERNATIVE KEYCAPS

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.
