Magnetic Switch

Adjustable Actuation Point

Customise each key with precision, adjusting actuation points from 0.2 to 2.9 mm with 0.1 mm sensitivity. Set shallow keypresses for instant actions and deeper ones for deliberate engagement, minimising accidental touches and giving you an edge in both gaming and typing.

Last Key Priority (LKP) & Snap Click

LKP allows seamless directional changes by prioritising the last key pressed, ensuring smoother gameplay in titles like Valorant. With Snap Click, deeper keypresses take precedence when two keys are hit at once, automatically resetting shallower presses.

*They are disabled by default, but you can easily enable them in Keychron's Launcher web app when needed.

One Key. Multiple Commands

Assign four actions to a single key based on the depth of your press. For example, lightly press a key to walk forward in a game, and press deeper to run. Additionally, releasing the key also supports two-stage settings. This allows for smoother, personalised combinations that can give you an edge in competitive gaming.

Dynamic Rapid Trigger

Activate or deactivate keys based on how far they travel, not predefined points. This means immediate key reactions—press to activate, release to reset—allowing for faster, more precise keystrokes. In rapid gameplay, this translates to executing complex actions in real-time without delay, giving you a serious advantage during fast-paced sequences.

Analogue Mode

Experience the power of Analogue Mode on your K3 HE, bringing game controller-like precision to your keyboard. This mode enables variable inputs instead of the usual on/off signals, letting you achieve more fluid and dynamic control.

With each keypress, the K3 HE detects how far you press, translating it into different speeds and intensities. Enjoy nuanced control and heightened responsiveness in racing games, sports simulations, and more.

Launcher Web App

Programme with QMK & Launcher

The open-source QMK firmware means endless possibilities for key remapping, macros, shortcuts, and more. Now you can easily customise each key with the Keychron Launcher web app.

Experience peak gaming performance on the fly with the K3 HE's 2.4 GHz wireless connection boasting a rapid 1000 Hz polling rate. For seamless multitasking across your computer, phone, and tablet, you can effortlessly connect the K3 HE via Bluetooth 5.2 to three devices.

Powerful ARM Core

An Epic Core Inside the Keyboard

Engineered with a powerful chip (MCU), 256K flash, and QMK open-source firmware to provide more flexibility for developers. The polling rate is 1000 Hz out of the box in Type-C wired mode and 2.4 GHz mode, which greatly helps when competitively gaming.
