Walk into any mechanical keyboard discussion and you'll immediately encounter a confusing rainbow of switch names: Cherry MX Red, Gateron Brown, Kailh Box White. What do these colors mean? Which one is right for you?
This guide demystifies mechanical switches, explaining the three main categories and helping you choose the right switch for your typing or gaming style.
What Is a Mechanical Switch?
Unlike membrane keyboards where you press a rubber dome, mechanical keyboards use individual mechanical switches under each key. Each switch contains:
- A stem: The plastic piece that moves when you press the key
- A spring: Provides resistance and returns the key to the top
- Contact points: Register when the key has been pressed
The way these components interact determines how the switch feels and sounds—and different designs create dramatically different typing experiences.
The Three Main Categories
Linear Switches (Red, Black, Yellow)
Linear switches have smooth, consistent resistance from top to bottom. There's no bump or click—just a straight press down and back up.
Characteristics:
- Smooth, quiet keypresses
- Consistent force throughout the keystroke
- Faster actuation for gaming (less distance to register)
Popular options:
- Cherry MX Red (45g): Light, smooth, the classic gaming choice
- Cherry MX Black (60g): Heavier, reduces accidental presses
- Gateron Yellow (50g): A community favorite for smoothness and value
Best for: Gamers who want fast keypresses, typists who don't like feedback bumps
Tactile Switches (Brown, Clear, Ergo)
Tactile switches provide a noticeable "bump" partway through the keypress. This bump indicates that the key has registered without needing to bottom out.
The tactile bump gives your fingers feedback that the key registered, reducing finger fatigue because you don't need to press all the way down.
Characteristics:
- Bump feedback indicates actuation point
- Quieter than clicky switches
- More satisfying than linears for many typists
Popular options:
- Cherry MX Brown (45g): Light tactile bump, widely available
- Cherry MX Clear (55g): Heavier with more pronounced bump
- Holy Panda: Enthusiast favorite with large, rounded tactility
Best for: Typists who want feedback without noise, office environments
Clicky Switches (Blue, Green, White)
Clicky switches combine a tactile bump with an audible "click" sound. They're the most stereotypically "mechanical keyboard" experience.
Characteristics:
- Loud click on each keypress
- Maximum feedback (tactile + auditory)
- Satisfying for typists; annoying for everyone nearby
Popular options:
- Cherry MX Blue (50g): The classic clicky switch
- Kailh Box White (45g): Sharper, crisper click mechanism
- Cherry MX Green (80g): Heavy, loud, for those who love resistance
Best for: Typists working alone who love audio feedback, those seeking the classic typewriter feel
Beyond Cherry: Switch Manufacturers
Cherry MX pioneered colored switch naming, but many manufacturers now produce excellent alternatives:
- Gateron: Often smoother than Cherry, excellent value
- Kailh: Innovative designs including Box switches with improved durability
- Durock/JWK: Premium smoothness, favorite among enthusiasts
- Akko: Budget-friendly with surprisingly good quality
Colors generally follow Cherry's convention (Red = linear, Brown = tactile, Blue = clicky), but specialty switches may differ.
How to Choose
Ask yourself:
- Primary use: Gaming favors linears; typing favors tactiles or clickies
- Environment: Shared spaces need quieter linears or tactiles; private spaces can handle clickies
- Personal preference: There's no objectively "best" switch—only best for you
If possible, buy a switch tester with multiple switch types before committing to a full keyboard. Typing on a switch for 5 seconds tells you more than any review.
The Bottom Line
Mechanical switches are deeply personal. Some people swear by the smooth travel of linears; others can't type without tactile feedback; and a dedicated subset loves the clicky click. Understanding the three categories—linear, tactile, and clicky—is the first step to finding your perfect switch.
