Designed for Magnetic Keyboards

Built exclusively for compatible Keychron HE 8K Series, Keychron HE 1K Ultra-Fast Lime version keyboards, Lemokey L0 HE, or L5 HE keyboards to unlock advanced performance features such as adjustable actuation, LKP & snap click, multi-stage inputs, and rapid trigger.

Adjustable Actuation Point

Customize each key with fine-grained actuation control. 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 on Keychron magnetic switches

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.

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 Keystrokes: up to four actions on one Keychron magnetic switch

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.

Compatible Keyboard:

Compatible keyboard: Keychron HE 8K series, Keychron HE 1K Ultra-Fast Lime version keyboards, Lemokey L0 HE and L5 HE keyboards.

Note: After replacing switches, recalibrate the affected keys if required by your keyboard model.
