How to choose a mechanical keyboard
Switch feel and layout size decide whether you keep the board. Everything else is refinement.
Switch type
Linear switches move smoothly with no feedback and suit gaming and fast typing. Tactile switches have a bump at the actuation point, which most typists prefer. Clicky switches add noise and are unwelcome in shared rooms. Actuation force is a secondary preference: heavier springs reduce accidental presses and tire the hand faster.
Magnetic switches are a different product
Hall effect and TMR switches read position continuously rather than as on or off. That gives adjustable actuation depth and rapid trigger, which matter in a few competitive games and nowhere else. They cost more and the switch choice is usually fixed.
Layout size is a daily decision
Full size keeps the numpad. TKL drops it and returns desk space for the mouse. 75 and 65 percent keep the arrow keys. 60 percent puts arrows and function keys on a layer, which some people never adapt to. Decide by what you press daily, not by the photo.
Mount and sound
Gasket mounted boards flex slightly and sound softer. Tray mount is firmer and usually louder and sharper. Case material, plate material and any internal foam change the sound more than the switch does.
Keycaps
PBT resists shine and holds texture. ABS goes glossy within months of heavy use. Check the legend method too: doubleshot and dye sublimated legends do not wear off, printed ones do.
Firmware
QMK and VIA support means remapping without vendor software and without a cloud account. Proprietary software is fine until it stops being updated.
Common mistakes
- Buying clicky switches for an office.
- Choosing a 60 percent board and then needing the function row for work every day.
- Assuming hot swap sockets survive constant switch changing. They do not.
