Operating Instructions
Key Switch Types
The MX Mechanical Mini is available with three distinct low-profile mechanical key switch types, each offering a unique typing experience:
- Linear (Smooth Typing): These switches provide uninterrupted key travel with minimal spring force, resulting in fast reactivity and an ultra-smooth typing feeling. They are generally quieter.
