The ergonomic 75% design of the Keychron K3 Version 2 is a more compact version of the TKL layout, optimized for productivity. It provides access to all essential multimedia and function keys, but with a smaller footprint. The specially designed low-profile switches are 40% slimmer than traditional switches. Along with the streamlined aluminum casing, the K3 Version 2 is one of the thinnest and lightest wireless keyboards in the world. Its Keychron Low Profile Optical Switches in MX style are designed for heavy typists and gamers who want to type at lightning speed, featuring an extremely low latency of 0.2 ms. Additionally, they boast a lifespan of 70 million keystrokes, far exceeding industry standards.

With this hot-swappable version, you never have to buy a new keyboard to try a different optical switch option – each switch can be changed in 5 seconds without soldering; just plug it in and you're done. The white backlighting of the K3 Version 2 makes typing in dark environments easier, and the angled bottom frame provides comfortable writing and gaming ergonomics. The K3 Version 2 connects to up to three devices via Bluetooth and easily switches between them.
