Advanced Acoustic Foams

Elevate your typing with the J12 HE, featuring multi-layer acoustic foam for smoother keystrokes and a more refined sound. Designed for magnetic switches, the refined internal structure delivers smoother keystrokes, stable feedback, and precise responsiveness.

Keychron Ultra-Fast Lime Magnetic Switches

The Keychron J12 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, they deliver an incredibly satisfying, soft, and thocky typing sound, enhancing every keystroke for a more enjoyable typing experience.

Hot-Swappable

Unlike mechanical switches that rely on physical contact, magnetic switches detect key presses through magnetic fields — making them smoother, more durable, and easy to swap out with compatible magnetic switches.

The J12 HE is compatible with the magnetic switches sold on the Keychron website only.

RGB Backlighting

Comes with more than 22 RGB backlight settings (as well as a static white backlight option), and 14 types of backlight settings on the White Backlight version. You can further fine-tune the RGB hue, saturation, brightness, and effect speed with ease.
