ERGONOMIC ANGLE DESIGN

Two level adjustable rubber feet makes the K5 SE more comfortable to type on.

K5 SE LAYOUT

Full Size

Comes with a 104 key full size layout included number pad that offers convenient access to all the essential keys* for Mac and Windows included the dedicated Screenshot Key, Siri (Cortana) Key. *Num Lock works with Windows OS only.

HOT-SWAPPABLE

You can easily hot-swap every Optical switch or Gateron switch (hot-swappable) version in a few seconds to customize your typing experience on the K5 SE without soldering.

*Hot-swappable feature is available for low profile Keychron Optical switch and low profile Gateron Mechanical (Hot-swappable) versions only. *Low Profile Keychron Optical and Low Profile Gateron mechanical version keyboards are NOT compatible with any normal profile mx style mechanical switch.

Mechanical Or Optical?

Available in Gateron mechanical and Keychron optical low profile switch to elevate the typing experience with a more slimmer and subtle look, the K5 SE provides an excellent typing performance, whether you prefer linear (Red), clicky (Blue), or something in between (Brown, Banana, Mint).

Low-Profile Mechanical

Durable and ultra-slim low profile Gateron Mechanical switch with a 50 million keystroke lifespan to provide an unrivaled tactile responsiveness. K5 SE was designed to boost your productivity yet meets your desktop aesthetics perfectly. Classic clicky tactile or quicker response, for office or personal gaming, the Gateron low profile is the way to choose.

Low-Profile Optical

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

The Banana and Mint switches comes with an early tactile bump of every downstroke like those Panda switches, that's the main difference between the Banana/Mint and the Brown switch. More add-on switches here.

 SLIM YET DURABLE

The aircraft-grade reinforced aluminum frame as a pillar to make the K5 SE durable yet elegantly slim. A SGCC galvanized steel plate is added to the plastic bottom frame in order to strengthen the K5 SE's body structure, while still maintaining a stable wireless transmission capability of the K5 SE.

MX STYLE STEM

We developed an MX-style stem on the K5 SE's low-profile switches as well as stabilizers on the big keys (e.g.: space bar, left Shift, backspace, and Enter key) in an attempt to revamp the reliability. Read more here.
