Red vs brown vs blue switches

The red, brown and blue naming comes from Cherry, the German company whose MX switch became the template for nearly every mechanical keyboard switch made today. Cherry color coded its stems so you could tell the variants apart at a glance, and other makers such as Gateron, Outemu and Kailh copied the scheme for their MX-compatible clones. That is why a budget keyboard listing can say "brown switches" without naming a brand. The color tells you the switch family. It does not tell you who made it or exactly how it feels, and those details matter more than most listings admit.

The short version

• Red is linear. The key moves straight down with no bump and no click. Resistance rises smoothly from the spring and that is all you feel.
• Brown is tactile. There is a small bump partway down the stroke that tells your finger the key is about to register. No deliberate click sound.
• Blue is clicky. There is a sharper bump plus an audible click produced by a separate part inside the switch. It is the loudest of the three by a wide margin.

If you want to hear the difference before reading further, open the keyboard simulator, pick Cherry MX Red, then MX Brown, then MX Blue, and type a sentence on each. The sounds are simulated from the published specs rather than recorded, but the gap between a linear and a clicky is obvious within a few keystrokes.

The numbers, side by side

These are the figures from the site's own switch library, which separates the force a brand publishes at actuation from the force at the tactile peak and at bottom-out. That separation matters, because brands do not all rate the same point of the stroke.

Two things stand out. First, the three Cherry switches are almost the same weight. A Brown is not a heavier Red; it is a Red with a bump added, and the bump itself is the extra resistance you feel. Second, the same color does not mean the same weight across brands. Both Cherry and Gateron quote force at actuation, yet Gateron's Brown and Blue are rated 10 g heavier than Cherry's. Spring curves and tolerances also vary, so read what actuation force means before treating a few grams on a spec sheet as decisive.

Red: the linear

A red switch has a plain stem with no bump leg. Press it and the only thing pushing back is the spring, which gets firmer the further you go. Nothing in the stroke tells you where the key registers (2 mm down on a Cherry MX Red), so most people press all the way to the bottom until they adapt.

That predictability is why reds dominate gaming keyboards. Held movement keys feel identical every time, double taps are fast because there is no bump to reset, and the light 45 g actuation is easy to hold for hours. The tradeoff shows up in typing: with no feedback, light-fingered typists can brush a neighboring key hard enough to trigger it. If that sounds like you, a heavier linear such as the Gateron Yellow or MX Black keeps the smooth stroke and adds a little margin against accidental presses.

Brown: the tactile

A brown switch adds a small bump to the stem leg. You feel it as a brief rise in resistance just before the key registers, then the resistance drops away and the key falls to the bottom. In principle the bump lets you stop pressing once you feel it, which reduces bottoming out and finger fatigue.

In practice, the classic MX Brown bump is famously mild. Enthusiasts often describe it as barely there, and that reputation is the reason the hobby went looking for stronger tactiles like the Holy Panda and Zealios V2. For a beginner, though, the mild bump is a reasonable middle ground: you get some feedback, no click, and a switch that works acceptably for both games and long typing sessions. That is why brown is the color most often recommended to people who have no idea what they want yet.

Blue: the clicky

A blue switch uses a two-part stem. A separate plastic collar called a click jacket snaps past a ledge as you press, producing both a sharp tactile event and the high-pitched click that defines the switch. On the return stroke the jacket resets with a second, quieter click. The MX Blue registers a little later in the stroke than the other two, at 2.2 mm, and its 60 g tactile peak is the firmest of the three.

Blues are satisfying to type on and give the clearest confirmation of any common switch. They are also the switch most likely to annoy everyone around you, and the click carries clearly through a desk microphone. For gaming they are the weakest of the three, since the jacket mechanism has a small hysteresis: the point where the key resets on release is not the point where it actuated, which makes very fast repeated presses less precise. If you love the click but want something crisper, look at click bar designs such as the Kailh BOX Jade, which use a separate metal bar instead of a jacket. Our guide to switch types covers the different click mechanisms in more detail.

Noise: how loud is each one?

Red and brown sound much the same. Most of the noise from either one is the stem hitting the bottom of the housing and the keycap striking the plate, so the board, keycaps and how hard you type change the sound more than the color does. Blue adds a deliberate click on every press and release, so it is noticeably louder regardless of the board.

If you share a room or an office, rule out blue first. If you need genuinely quiet keys, none of the three is the answer: look at dampened switches such as the MX Silent Red, explained in our guide to silent switches, and read the quietest switches ranking.

How to choose

• Mostly gaming, fast reflex games: red, or another light linear.
• Mostly typing, quiet room or shared space: brown, or a stronger tactile if the bump feels too faint.
• Mostly typing, alone, you want feedback you can hear: blue.
• Mixed use and unsure: brown is the least likely to disappoint.
• Heavy-handed typist: consider a heavier linear or tactile rather than any of the light defaults.

If your keyboard is hot-swappable, the choice is less final than it looks. You can buy a small pack of a different color and swap a few keys to try them, which is the cheapest way to learn what you actually prefer. Our guide to hot-swap vs soldered boards explains how to tell whether yours supports it.
