2.3 Rapid Trigger Functionality

The K8 HE features Rapid Trigger, which allows keys to activate and reset based on real-time travel distance rather than fixed points. This enables faster, more precise keystrokes, particularly beneficial for competitive gaming.

2.4 Adjustable Actuation Point

Customize the actuation point for each key from 0.2 mm to 3.8 mm with 0.1 mm sensitivity. This allows you to fine-tune key responsiveness to your preference, reducing misfires and optimizing your typing or gaming style.

2.5 Dynamic Keystrokes (DKS)

Dynamic Keystrokes allow you to assign up to four different actions to a single key based on the press depth. For example, a light press could trigger one action, while a deeper press triggers another. This feature enhances efficiency and control, especially in games requiring layered inputs.

2.6 Snap Action

Snap Action, combined with Last Key Priority (LKP), prioritizes deeper keypresses when multiple keys are pressed. This feature contributes to smoother and more precise directional changes, particularly useful in fast-paced gaming scenarios.

2.7 RGB Lighting

The K8 HE features per-key RGB backlighting. Customize lighting effects, colors, and brightness through the Keychron Launcher software to match your setup or mood.

• Use a soft, lint-free cloth slightly dampened with water or a mild cleaning solution to wipe down keycaps and the frame.
• For dust and debris between keys, use compressed air.
• Avoid harsh chemicals or abrasive materials.

3.2 Hot-Swappable Switches and Keycaps

The K8 HE features hot-swappable Hall Effect switches, allowing you to easily replace them without soldering. Keycaps can also be removed for cleaning or customization.

• Removing Keycaps: Use the included keycap puller to gently lift keycaps straight up.
• Removing Switches: Use the included switch puller to carefully grip and pull the switch out.
• Installing Switches/Keycaps: Align the new switch/keycap with the socket and press down gently until it clicks into place. Ensure pins are not bent when installing switches.
