Mechanical Switch Types for Typing

A mechanical key registers partway through its travel, not at the end. On a typical switch with four millimetres of total travel, the signal is sent at around two — so half the movement after that point is doing nothing except decelerating your finger against the keyboard's base.

That gap is the whole reason switch feel matters for typing. If you cannot perceive the actuation point, you have no way to stop at it, so every keystroke travels the full distance and ends in an impact. Over a working day that is thousands of impacts you did not need to make.

A typist who can feel where the key registers can learn to release just past it, which shortens each keystroke and lets the next one begin sooner. This is a small effect per keystroke and a substantial one per hour, and it is the mechanism behind most claims that a particular switch is 'faster'.

A linear switch has a smooth, uniform resistance curve from top to bottom. Nothing marks the actuation point at all.

This is genuinely preferable for rapid repeated presses of the same key — a gaming pattern — because there is no bump to push past on each repeat, and because consistency matters more than information when you are pressing the same key many times.

For typing, the consequence follows from the section above: with no feedback, most people bottom out on every stroke. Some experienced typists learn to type linears lightly by developing a sense of the depth rather than of a physical cue, but that is a skill acquired despite the switch rather than because of it.

Linears are also the quietest of the three by a wide margin, which is not a small consideration in a shared room and is the reason many office typists choose them despite the above.

A tactile switch adds a bump to the resistance curve, positioned at or just before the actuation point. You feel it, you know the key has registered, and you can stop.

This is the feedback type that most directly addresses a typist's actual problem. It is why tactile switches dominate recommendations for typing while linears dominate them for gaming, and the split is not marketing — it follows from what each activity needs.

Bumps vary considerably in sharpness and placement, and the difference is larger than the marketing categories suggest. A gentle rounded bump gives a mild cue; a sharp one is unmistakable and can feel abrupt at speed. A bump placed early gives you more remaining travel to arrest in; one placed close to the bottom gives you less warning and less benefit.

If you are choosing without being able to try them, a moderate tactile bump placed early is the least likely to be wrong.

This is the most common misunderstanding in the category. The click is not the bump made louder. It is a distinct mechanism — typically a separate jacket or bar inside the switch — that produces an audible snap, and it can be present with a bump that is not especially pronounced.

So the sound and the tactile cue are separable, and the useful part for typing is the one you feel rather than the one you hear. Your fingers can act on a bump; your ears can only confirm afterwards, by which point the keystroke has already happened.

What the click does provide is confirmation that is pleasant, and there is nothing wrong with choosing it for that. What it does not provide is any additional ability to stop before bottoming out.

The practical cost is noise, which is substantial and carries. In a shared space or on a video call, clicky switches are a decision affecting other people, and that is worth weighing more heavily than most reviews do.

The reasoning above narrows the field; it does not pick a switch, and beyond a certain point the remaining differences are genuinely matters of taste.

Spring weight is one. Heavier springs resist accidental presses and tire some people; lighter ones are quicker and produce more accidental actuations for others. The threshold at which a spring becomes tiring varies enough between individuals that no recommendation covers everyone. Weight and travel are discussed properly in actuation force and key travel.

Smoothness is another. Some switches feel gritty as the stem moves in its housing; lubrication addresses it. Whether that difference is worth noticing depends on how sensitive you are to it, which varies enormously.

And sound signature — the pitch and character of the noise a board makes — is almost entirely aesthetic, is heavily influenced by the case and keycaps rather than the switch alone, and is a legitimate reason to prefer one board over another that has nothing to do with typing performance.

A switch tester — a small block holding a selection of switches — costs little and answers the question directly, and it is the only reliable way to know how a bump feels to your hands rather than how it is described.

If you cannot try before buying, the ordering that follows from the argument above is: tactile for typing, linear if noise matters more than feedback, clicky if you want the sound and the room permits it.

One caution about hot-swappable boards, which let you change switches without soldering. They are genuinely useful and they also make it easy to spend a long time chasing a marginally better feel. The gap between a reasonable switch and an optimal one is small compared with the gap between a good typing position and a poor one, and the position is free.
