Hello. What is the difference between brown, red or blue switches? Is it the sound?

Hi! The main differences between brown, red, and blue mechanical keyboard switches are in their sound and feel. These switch types belong to different mechanical keyboard switch designs and have distinct characteristics.

1. **Brown Switches**:
   - Sound: Brown switches are generally relatively quiet mechanical keyboard switches. When you press the keys, they produce a subtle "thock" sound, but it's relatively light.
   - Feel: Brown switches offer moderate resistance, requiring a moderate amount of force to press the keys. They are suitable for people who need to type but don't want to make much noise.

2. **Red Switches**:
   - Sound: Red switches are also relatively quiet mechanical keyboard switches, without a noticeable "click" sound. Pressing the keys feels smooth and doesn't produce a distinct sound.
   - Feel: Red switches are very light, requiring a light touch to activate the keys. They are ideal for users who need to rapidly and continuously press keys, such as gamers.

3. **Blue Switches**:
   - Sound: Blue switches are relatively loud mechanical keyboard switches. Pressing the keys produces a clear "click" sound, which some people enjoy, but others may find noisy.
   - Feel: Blue switches require a moderate amount of force, and they provide a noticeable tactile feedback. They are suitable for typists and users who appreciate a pronounced keypress feel.
