These keyboards support wired and wireless connections: wired USB-A or USB-C, wireless Bluetooth, and 2.4GHz RF. Several models explicitly offer tri-mode switching so you can switch between USB-C, Bluetooth, and 2.4GHz.
Most listings use mechanical switches, with some models offering Hall effect switches. Several keyboards include hot-swappable sockets compatible with 3‑pin or 5‑pin switches to make switch replacement easy.
Several listings highlight durable PBT keycaps and manufacturing methods such as double‑injection molding, dye‑sublimation (heat sublimation), or side‑engraving to resist fading and wear.
A number of models include extra controls like a multi-function knob (for volume, lighting, or device switching) and an LCD or smart screen for quick system info, backlight control, and device management.
Some keyboards list long switch lifespans, commonly citing tested durability figures such as around 100 million keystrokes for the switches.
