What Are Mechanical Keyboard Switches? Explained

What a switch is

A mechanical keyboard switch is the individual mechanism beneath each key that registers a press. Unlike a typical membrane keyboard, where all keys press down onto a single rubber-dome sheet, a mechanical keyboard has a separate spring-loaded switch for every key. Each switch has moving parts, a stem, a spring, and metal contacts, that physically actuate when pressed. This per-key mechanism is what gives mechanical keyboards their distinctive feel, durability, and the ability to be tuned to different typing preferences.

How they differ from membrane keyboards

Most inexpensive keyboards are membrane types: pressing a key pushes a rubber dome that completes a circuit on a shared membrane. They are cheap and quiet but can feel mushy and wear out over time. Mechanical switches instead give a crisper, more consistent feel, register the press at a defined point, and are rated for far more keystrokes, often tens of millions, so they last much longer. They also make a keyboard repairable and customizable, since individual switches and keycaps can be swapped.

The three main types

Switches broadly fall into three families based on feel. Linear switches move straight down smoothly with no bump, quiet and consistent, favored by many gamers. Tactile switches have a noticeable bump partway down that tells you the key has registered, popular for typing. Clicky switches add an audible click to that tactile bump, satisfying to some and annoying to others nearby. The right family is a matter of personal preference for feel and noise, there is no objectively best type.

Actuation and travel

Two useful concepts describe how a switch behaves. Actuation point is how far down you must press before the keystroke registers, some switches actuate with a light, short press, others need more. Total travel is how far the key can go down overall. Switches also vary in the force required to press them, measured in grams. Lighter switches can feel faster and less tiring; heavier ones give more deliberate feedback and can reduce accidental presses. These specs let you match a switch to your typing style.

Sound and feel customization

Part of the appeal of mechanical keyboards is how much you can tailor them. Beyond choosing a switch type, enthusiasts change keycaps (which affect sound and feel), add dampening, and, on 'hot-swappable' boards, pop switches in and out without soldering to try different ones. This has grown into a whole hobby around tuning exactly how a keyboard sounds and feels. But even casually, simply picking the right switch type gets you most of the benefit for everyday typing or gaming.

How to choose

Start with how you will use the keyboard and where. For quiet offices, avoid clicky switches, choose linear or tactile. For gaming, many prefer light linear switches for fast repeated presses. For lots of typing, tactile switches offer helpful feedback. If possible, try a switch tester or a friend's keyboard, since feel is subjective. And consider a hot-swappable board if you want to experiment. There is no wrong answer, only what feels best to your fingers, which is exactly why mechanical keyboards are so popular.
