Linear Action Models (Red, Silent Red, Black)
Linear Action means when pressing the key feels smooth. There is no bump feel or click noise.
Linear Action Models include: Red, Silent Red, Black. They differ by the force of the spring.
- MX Red requires the least pressure to activate the key. It's really nice. Typing on it is effortless.
- MX Silent Red is a quieter, but require slightly more force to activate.
- Cherry MX Black is same as Red, except more force is required. I don't like MX Black at all.
Tactile Action Models: Brown
The MX Brown switch have a tactile bump. When you press down, after certain point, there's a bump feel.
Click Action Models: Blue
The MX Blue switch has a strong clicky bump. When you press down, the is a very sharp click point. Blue is very noisy. It makes a “click” sound by design.
There are many other color-coded Cherry MX switches, but less common.
