Mechanical keyboard discussions have a habit of going straight to actuation force curves and stem materials, which is not much help if you just want to know whether the clicky ones will annoy your colleagues. They will, by the way. We will come back to that.
This is a plain explanation of what the three switch families actually feel like, what the numbers on the spec sheet mean in practice, and how to choose without spending a fortune finding out you picked wrong.
Quick Facts
- There are three families: linear (smooth), tactile (a bump partway down) and clicky (a bump plus a loud click).
- Actuation force is measured in grams. Most switches sit between 45g and 67g. Lower is lighter to press, not necessarily better.
- Actuation point is how far down the key registers, typically 1.2mm to 2.0mm of a 3.5mm to 4.0mm total travel.
- Hot-swappable boards let you change switches with no soldering. The single most useful feature for a first mechanical keyboard.
- A switch tester costs a few pounds and settles the argument in five minutes.
The three families, without the jargon
Linear switches go straight down with no interruption. Nothing happens between the top and the bottom of the press except the spring getting slightly stiffer. Gamers tend to prefer them because there is nothing in the way of a fast repeated press, and they are the quietest of the three by a clear margin.
Tactile switches have a small bump partway down that you can feel when the key registers. For typing, most people find this the most satisfying option. You get confirmation through your finger rather than having to bottom out every key. They are slightly louder than linears but not by much.
Clicky switches are tactile switches with a mechanism added specifically to make a sharp click. They sound fantastic. In a shared office they are genuinely antisocial, and on a video call your microphone will pick up every keystroke. If you work alone in a room with a closed door, enjoy them. Otherwise, do not.
What the spec numbers mean
| Spec | Typical range | What it means for you |
| Actuation force | 45g to 67g | How hard you press. Lighter tires you less; heavier reduces typos from resting fingers. |
| Actuation point | 1.2mm to 2.0mm | How far down before it registers. Shorter feels faster and is easier to trigger accidentally. |
| Total travel | 3.4mm to 4.0mm | How far the key goes before it stops. Shorter travel feels snappier, longer feels more cushioned. |
| Bottom-out force | 55g to 80g | The force at the very bottom. Relevant only if you type heavily. |
| Rated lifespan | 50 to 100 million presses | Effectively irrelevant. The board will be replaced long before this matters. |
If you take one number from that table, make it actuation force. Everything else is refinement; that one changes how your hands feel after six hours.
The colour naming, and why it is confusing
Switch colours started as a Cherry MX convention. Red for linear, brown for tactile, blue for clicky, black for a heavier linear. Every other manufacturer then adopted approximately the same scheme, with enough variation to be misleading.
A Gateron Brown and a Cherry MX Brown are both tactile but feel noticeably different. A Kailh Box White is clicky where a Cherry MX White is not. Treat the colour as a rough family indicator and read the actual specification.
| Colour | Usually means | Good for |
| Red | Light linear, around 45g | Gaming, quiet offices |
| Black | Heavy linear, around 60g | Heavy typists who dislike accidental presses |
| Brown | Light tactile, around 45g to 55g | The safe all-round first choice |
| Blue | Clicky, around 50g to 60g | Working alone, and only then |
| Silent variants | Dampened linear or tactile | Shared spaces and video calls |
How to choose without guessing
Quick Steps
- Buy a switch tester with six to nine switches on it, for the price of a couple of coffees.
- Press each one for a minute, not a second. First impressions favour dramatic switches you will tire of.
- Note which one you keep going back to, then check its actuation force.
- Buy a hot-swappable board so you can change your mind later without a soldering iron.
- If you cannot test first and must simply pick, choose a light tactile. It is the option fewest people regret.
The things nobody mentions until afterwards
- The case matters as much as the switch. A gasket-mounted board with foam sounds and feels completely different to a hollow plastic one with identical switches.
- Keycaps change the sound noticeably. Thicker PBT caps give a lower, less hollow sound than the thin ABS ones that ship with budget boards.
- Silent switches are a real category, not marketing. They have dampening pads inside and genuinely cut noise, at the cost of a slightly mushy bottom-out.
- Lubing is optional. It makes good switches better, it takes an evening, and you do not need to do it to enjoy the keyboard.
- Layout is a bigger decision than switches. Going from full size to 65% is a much larger adjustment than red to brown, and it is the change people most often undo.

Glossary
| Term | What it means |
| Actuation | The point in the keypress where the keyboard registers the key. |
| Bottoming out | Pressing the key all the way to the base rather than stopping at actuation. |
| Hot-swap | A socket design that lets switches be pulled and replaced by hand. |
| Linear | A switch with smooth, uninterrupted travel. |
| Tactile | A switch with a felt bump at the actuation point. |
| PBT and ABS | Two keycap plastics. PBT is harder-wearing and does not develop a shine. |
| Gasket mount | A construction where the plate sits on rubber strips, giving a softer typing feel. |
Frequently asked questions
Are mechanical keyboards actually better for typing?
For most people, yes. The feedback and consistency make sustained typing more comfortable. It is a preference rather than a fact, though, and a good membrane board beats a cheap mechanical one.
Which switch is quietest?
A silent linear, such as a Cherry MX Silent Red or Gateron Silent variant. Standard linears are next. Clicky switches are the loudest by a wide margin and are not suitable for shared offices.
What does hot-swappable mean and is it worth it?
It means the switches sit in sockets rather than being soldered, so you can pull one out with a puller tool and push another in. For a first mechanical keyboard it is absolutely worth it, because it makes an expensive mistake into a cheap one.
Do I need to lubricate my switches?
No. It smooths the feel and reduces spring noise, and enthusiasts enjoy doing it, but a factory-lubed switch from a decent manufacturer is perfectly good out of the box.
Will a mechanical keyboard help my gaming?
Marginally, through consistency and a shorter actuation point. Any difference is far smaller than the marketing suggests, and comfort matters more over a long session.
