Mechanical Switches Explained

Linear? Tactile? Clicky? We break down the jargon so you can choose the perfect switch for your fingers.

Test Your Keyboard

The beauty of mechanical keyboards is customizability. The most important choice you will make is the "switch" – the mechanism under each keycap. This guide explains the three main types.


The 3 Main Switch Types

Linear (Red)
Smooth

No bump, no click. Just a smooth travel from top to bottom.

  • Best for Gaming
  • Quietest
  • Easy to make typos
Tactile (Brown)
Bump

A small bump you can feel when the key activates, but no loud click.

  • Best Hybrid
  • Great for typing
  • Moderate noise
Clicky (Blue)
Loud

A bump plus a loud "click" sound. Very satisfying but noisy.

  • Heavy Typists
  • Audible feedback
  • Bad for office/streaming

Switch Color Reference Guide

Color Type Feel Noise
Red Linear Smooth, Light Quiet
Black Linear Smooth, Heavy Quiet
Brown Tactile Light Bump Moderate
Clear Tactile Heavy Bump Moderate
Blue Clicky Clicky Bump Loud
Green Clicky Heavy Click Very Loud

*Note: Colors are based on the Cherry MX standard, but most brands (Gateron, Kailh) follow this scheme.


Popular Switch Brands Compared

Not all switches are created equal. Here are the major players in the market.

Brand Reputation Price Best For
Cherry MX The Gold Standard High Durability & Consistency. The original mechanical switch.
Gateron Smoother Clone Medium Enthusiasts who want a smoother feel than Cherry. Great value.
Kailh Innovator Medium Unique distinctions like "Box" switches (dust/water resistant) and click bars.
Outemu Budget King Low Entry-level mechanical keyboards. Decent feel but more key wobble.

Beyond Standard: Specialty Switches

Optical Switches

Use light beams instead of metal contacts. Theoretically faster response times and double the lifespan (100M clicks). Popular in esports.

Low Profile

Shorter switches for slimmer keyboards. Shorter travel distance means faster actuation but a different, "laptop-like" typing feel.

Silent Switches

Internal dampeners reduce the "clack" sound on the downstroke and upstroke. Perfect for open offices (e.g., Cherry MX Silent Red).

Speed Switches

Actuate at 1.1mm-1.2mm (vs standard 2.0mm). Extremely sensitive. Great for gaming reflexes, annoying for typing (ghost presses).


Which Switch Should You Choose?

The Gamer

Recommendation: Linear (Red, Silver) or Optical.

You need speed and consistency. No bumps to distract rapid tapping.

The Writer

Recommendation: Clicky (Blue) or Tactile (Brown).

Rhythm matters. The physical feedback helps you know a key is pressed without bottoming out.

The Office Worker

Recommendation: Tactile (Brown) or Silent Red.

You want the mechanical feel without your coworkers plotting your demise due to the noise.

Sound Profiles: Thock vs. Clack

Enthusiasts often describe switch sounds with these terms:

  • Thock: A deep, bass-heavy sound (like wood blocks hitting). Often achieved with lubed linear switches and thick keycaps.
  • Clack: A higher-pitched, crisp sound. Typical of un-lubed switches or clicky switches.
  • Ping: A metallic ringing noise from the spring. Bad. Get rid of it by lubing the springs!

Key Terms You Should Know

Actuation Point
The exact depth you need to press a key for the computer to register it. Speed switches have a high actuation point (1.2mm); standard is 2.0mm.
Actuation Force
How hard you have to press. Measured in grams (cN). Red is light (45g), Black is heavy (60g).
Bottom Out
Pressing the key all the way down until it hits the backplate. Mechanical switches don't need to be bottomed out to register.
Travel Distance
The total distance a key can move. Standard is 4.0mm.

Frequently Asked Questions

Red or "Speed Silver" switches are generally considered the fastest. Their linear nature and often shorter actuation paths allow for rapid-fire keypresses without resistance.

It depends on your keyboard. If your keyboard features a "Hot-Swap" PCB, you can pull switches out and replace them without soldering. Standard keyboards require desoldering to change switches.

Most mechanical switches are rated for 50 million to 100 million keystrokes, which is decades of heavy use. Regular cleaning helps maximize this lifespan.
