Powerful Core Inside
Hot-Swappable (Optional)
Every detail matters for a personalized typing experience, so we empower you. You can hot-swap almost all 3-pin and 5-pin MX style mechanical switches on the market (including Cherry, Gateron, Kailh, Panda, etc.) on the K2 Max without soldering. You can customize your typing experience in seconds.
Keychron K Pro Switches
Our exclusive Keychron K Pro switches feature a new mold with unparalleled precision. Each switch is professionally quality-tested and has a lifespan of up to 50 million clicks, providing excellent reliability and high performance for long typing sessions. Its new light guide structure with a transparent top housing also ensures high light transmittance and more consistent, brighter backlighting.
OSA Profile Double-Shot PBT Keycaps
To further fine-tune your typing experience, the K2 Max is equipped with our unique OSA profile (OEM profile with spherical angle) and double-shot PBT keycaps, designed to provide a more comfortable fingertip feel and excellent oil resistance for long-term use on a 75% layout.
Screw-In PCB Stabilizers
Even small parts matter for your fingertip feel. We've integrated PCB-mounted screw-in stabilizers for a smoother typing experience on large keys (like spacebar, Shift, Enter, and Delete), reducing wobbliness. The Keychron K2 Max also supports third-party screw-in PCB stabilizers.
RGB Backlight
The RGB design is intended to better illuminate the keyboard backlight from the typist's perspective. The RGB will not be interfered with when the user installs alternate Cherry profile keycaps on the keyboard. With over 22 RGB backlight settings, you can easily further fine-tune the RGB's hue, saturation, brightness, and effect speed.
Ergonomic Support
Three adjustable typing angles (5º, 9º, and 12º) and curved OSA profile keycaps work together to provide long-lasting ergonomic support, caring for your wrists.
