Keychron Ultra Fast Lime Magnetic Switch
The Keychron C3 HE comes with pre-lubed Keychron Ultra-Fast Lime Magnetic Switches for an ultra-stable and ultra-responsive typing experience with an industry-leading, lightning-fast response time, and precise control over the way your keyboard feels and responds.
Made from POM material, it delivers an incredibly satisfying, soft, and thicky typing sound, enhancing every keystroke for a more enjoyable typing experience.


ADJUSTABLE ACTUATION POINT
Customize each key with precision, adjusting actuation points from 0.1 to 3.35 mm with 0.01 mm sensitivity. Set shallow keypresses for instant actions and deeper ones for deliberate engagement, minimizing accidental touches and giving you an edge in both gaming and typing.
LAST KEY PRIORITY (LKP) & SNAP CLICK
LKP allows seamless directional changes by prioritizing 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 our Launcher web app when needed.


ONE KEY. MULTIPLE ACTIONS
Thanks to Dynamic Keystrokes (DKS), you can now assign up to 4 distinct actions per key based on press depth. A light press moves your character, a deeper press makes them run, and releasing the key enables additional commands. This layered control lets you execute multiple moves with ease.
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.


ANALOG MODE
Experience the power of Analog Mode on your C3 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 C3 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.


Cherry Profile Double-shot PBT Keycaps
The ergonomically sculpted shape of Cherry keycaps helps your fingers naturally find the right keys, offering quieter, more muted sound and reduced typing fatigue over long sessions. C3 HE combines this with double-shot PBT technology to deliver a superior durability and long-lasting legends.

Screw-In PCB Stabilizers
Even small part matters for your fingertip feel. We’ve integrated the PCB-mounted screw-in stabilizers for a smoother typing experience with less wobbliness on the big keys such as space bar, shift, enter, and delete. The Keychron K8 Max also supports third-party screw-in PCB stabilizers.

North-facing RGB Backlights
The south-facing RGB is designed to better illuminate the keyboard backlight from the typist’s angle. The south-facing RGB is also free from interference when the user installs Cherry-profile alternative keycaps on their keyboard.
Comes with more than 22 types of RGB backlight settings. You can further fine-tune the RGB hue, saturation, brightness, effect speed with ease.

Ergonomic Support
Three levels of adjustable typing angle (4.6º & 8.7º) and cherry profile mfffcv keycaps are all working together to provide long-lasting ergonomic support for your wrist.
