Keychron B33 vs Lemokey X4: your questions
The B33 uses a scissor switch mechanism, not traditional mechanical switches. Keychron describes it as having an innovative scissor design that is taller than standard for more accurate and quieter keystrokes. It provides a low-profile, silent typing experience different from a standard mechanical keyboard.
Yes, the Lemokey X4 features a hot-swappable PCB. This allows you to easily remove and replace the mechanical switches without any soldering required, as long as you use compatible 3-pin or 5-pin switches.
Both keyboards are compatible with macOS, Windows, and Linux. The B33 includes a physical system toggle switch to change between Windows and macOS layouts. The X4's compatibility is managed through its QMK firmware and the Lemokey Launcher web app.
