• Hot-Swappable Mechanical Switches

  The full-key hot-swappable design supports most 3/5-pin switches, allowing for easy customization and replacement. The keyboard comes with high-quality satellite stabilizers and pre-lubricated linear red switches, providing a quiet and smooth typing experience with high precision and fast response.

• Gasket Mount Structure with Sound-Absorbing Foams

  Engineered with a gasket mount design and multi-layer sound-absorbing and shock-absorbing foams (including EVA cotton, IXPE foam pad, PET premium sound pad, bottom cotton, and silicone pad), the AK820 significantly reduces vibration and noise. This construction isolates the plate and PCB from the case, providing a focused and comfortable acoustic profile. The 1.2 mm PCB board slotting and PC positioning board slotting further optimize resilience and stability for a softer, more elastic feel.

• CNC Knob & Fn Multi-Function Key

  The integrated CNC knob allows for independent volume adjustment by twisting and play/pause control by pressing. This durable knob is designed for longevity. The Fn key provides access to various functional controls for both Mac and Windows operating systems when combined with other keys.

  The keyboard features a white LED backlight with 20 lighting effects, 5 brightness levels, and 5 lighting speeds. North-facing LEDs and high light transmittance ensure characters are clearly visible. Custom keyboard driver software is available to personalize lighting modes, brightness, and speed.
