Mechanical Keyboard Switches Explained: Clicky, Tactile, or Linear?

What a Mechanical Switch Actually Is

A mechanical switch is a self contained mechanism under each keycap: a spring, a stem, two metal contact leaves, and a housing. Press the stem and the leaves close a circuit at a fixed depth. That depth is the actuation point, and it usually sits between 1.2 mm and 2.0 mm of travel on a switch with 3.5 mm to 4.0 mm of total travel. The spring weight, the stem shape, and whether the housing adds a click mechanism define the three properties buyers actually feel: force, feedback, and sound.

Every mechanical keyboard, from a $30 board to a $300 custom build, is built on this same three category taxonomy. Learn the categories once and every product page reads the same way.

The Three Switch Families

Linear

Linear switches move straight down with no bump and no click. The force curve is smooth from the top of the keypress to the bottom. Cherry MX Red actuates at 45 g, Gateron Yellow at roughly 50 g, and Cherry MX Speed Silver shortens actuation to 1.2 mm for faster triggering. Because nothing interrupts the stroke, linears register keypresses quickly and feel light, which is why they dominate gaming. The trade off is zero physical confirmation, so a typist who rests fingers on the keys can bottom out or misfire more often.

Tactile

Tactile switches add a bump you feel just before actuation, without a separate click sound. Cherry MX Brown is the reference point at 55 g, while enthusiast options such as the Boba U4T (around 62 g) and the Gazzew Boba U4 (a silent tactile) sharpen or soften that bump. The feedback tells your finger the key registered, which reduces typos during long typing sessions and suits writing and coding. Bottoming out still produces a soft thock, so tactile is quieter than clicky but not silent.

Clicky

Clicky switches use a separate click bar or click jacket to fire an audible snap at the actuation point along with the tactile bump. Cherry MX Blue sits at 60 g and Kailh Box White at roughly 50 g with a crisp click. The sound is the point for people who like typewriter feedback, and it is the problem for anyone on open microphones. Measured a foot away, a clicky board runs noticeably louder than a linear or tactile one, and that noise carries on video calls even through a noise gate.

Actuation Force and Travel, Side by Side

Actuation force is the grams of pressure needed to register a key. Light switches (35 g to 45 g) reward speed but punish resting fingers. Medium switches (45 g to 55 g) feel closest to a laptop keyboard and suit most all day typing. Heavy switches (60 g to 67 g and up) demand deliberate presses, cut accidental actuations, and can fatigue fingers over an eight hour day. Travel and actuation depth matter too: a standard switch actuates near 2.0 mm of a 4.0 mm stroke, while speed variants drop to 1.2 mm.

Not sure which weight fits your hands and your workload? The keyboard switch finder walks through use case, noise tolerance, and force preference and returns a shortlist of switches to try.

Cherry MX vs Gateron vs Kailh

The switch category tells you feel; the manufacturer tells you consistency and price. Cherry MX is the German original, known for tight quality control and a slightly scratchier stock feel, priced around $0.30 to $0.50 per switch. Gateron, based in China, produces smoother linears out of the box and often undercuts Cherry at $0.25 to $0.35 per switch, which is why boards like the Keychron K8 ship with Gateron. Kailh, the retail arm of Kaihua, owns the Box housing that seals the stem against dust and adds a crisper click on its clicky line. A full board needs 61 to 104 switches, so a $0.10 per switch difference adds $6 to $10 to a build.

Silent Switches and Hot Swap Boards

Silent variants such as Cherry MX Silent Red and Gazzew Boba U4 add rubber dampeners inside the housing that mute the bottom out and the return. They cut the loudest part of a keystroke at the cost of a slightly softer, mushier travel. For a fully open microphone in a quiet room, silent linear or silent tactile is the closest a mechanical board gets to a laptop keyboard in volume.

A hot swap board holds each switch in a socket instead of a soldered joint, so you can pull a switch with a puller and press in another in seconds. Swapping a full board of 87 switches takes about 20 minutes and needs no soldering iron. Keychron, GMMK, Akko, and NuPhy all sell hot swap boards at no meaningful price premium, which means one keyboard can move from tactile to linear as your preference changes.

What Else Shapes Feel and Sound

The switch sets the baseline, but three cheap factors move it further. Stem plastic matters: POM stems (used in Gateron Ink and many linears) glide more smoothly than the nylon stems in stock Cherry, which is why POM switches feel less scratchy out of the box. Factory lube, a thin film of grease on the stem rails and spring, cuts spring ping and scratch; pre-lubed switches such as the Gateron Oil King ship with it, and hand lubing a set of 87 switches takes about an hour with a $6 brush and a syringe of Krytox 205g0.

The board around the switch changes the sound just as much. A gasket-mounted plate softens and deepens the bottom out compared with a rigid tray mount, and adding a layer of case foam or a poron plate pad removes hollow echo. On the same MX Brown switch, a foamed gasket board can sound like a muted thock while a bare tray board rings and rattles. None of this changes the actuation force or the category, but it explains why two boards with identical switches can sound completely different.

Which Switch for Which User

• Fast paced gaming: Linear at 45 g to 50 g (Cherry MX Red, Gateron Yellow), or a 1.2 mm speed silver for quicker triggering.
• All day typing and writing: Tactile at 55 g (Cherry MX Brown, Boba U4T) for feedback that reduces typos without a click.
• Solo office, loves feedback: Clicky at 50 g to 60 g (Kailh Box White, Cherry MX Blue) where noise is not a factor.
• Open microphone or shared room: Silent linear or silent tactile (MX Silent Red, Boba U4) to keep bottom out noise down.
• Undecided: A hot swap board plus a tester kit so you can change your mind for the price of new switches.

The three families and the force numbers are the whole framework. Match the category to how you work, pick a weight near 45 g to 55 g if you are unsure, and buy hot swap so the choice is never permanent.
