What Is a Clicky Keyboard and What Makes It Click? | Sound Built Into The Switch

A clicky keyboard is a mechanical keyboard whose switches produce an audible click and a tactile bump inside the switch itself, not through a speaker or software.

The first time you press a clicky key, the noise feels almost accidental — like something small and metal just snapped under your finger. It didn’t. That snap is designed, built into the switch housing, and it fires on every press whether the keyboard is plugged in or not.

Understanding what makes that sound is the difference between buying a keyboard you love and one your household asks you to return. Here’s the mechanism, the numbers behind the feel, and the mistakes that cost people a second purchase.

How Does A Clicky Switch Actually Make Its Sound?

A clicky switch generates its sound mechanically, from a two-part plastic stem or a flexing metal bar that snaps past a tension point as the key travels downward.

In a CHERRY MX Blue switch, the switching slide is built in two pieces. After the key passes its tactile point, the white component strikes the blue stem and drops, and that collision is the click you hear. CHERRY’s product page describes the two-part switching slide as part of the design.

The alternative approach is the click bar: a thin spring-steel bar that flexes and snaps past a tension point. Some click bars fire on press, others on the way back up, which is why two clicky keyboards can sound completely different despite both being “clicky.”

Clicky switches sit apart from the other two mechanical families. Tactile switches give you the bump with no intentional click. Linear switches give you neither — just smooth travel from top to bottom. Only clicky designs add the audible event on purpose.

Clicky Keyboard Specs That Shape Feel And Volume

Two numbers decide whether a clicky switch feels light or heavy and where the sound lands: actuation force and pre-travel distance.

Prices shift by retailer and region, so confirm the current figure on the manufacturer’s US page before you commit. CHERRY’s switch overview is a useful reference for how the MX family differs across blue, brown, and red variants.

Where Clicky Keyboards Go Wrong

The most expensive mistake is treating “mechanical” and “clicky” as synonyms — a mechanical keyboard can be linear, tactile, or clicky, and only the last one is built to snap.

Color is the second trap. Blue usually signals clicky and brown usually signals tactile, but those conventions are not standardized across manufacturers. Read the switch spec sheet, not the stem color.

Actuation versus bottom-out is the third. Actuation is the point where the keypress registers electrically; total travel is how far the key moves in full. CHERRY MX Blue actuates at 2.2 mm and bottoms out at 4.0 mm — two different distances people routinely blend together.

Sound is the fourth. Click jackets and click bars behave differently, and keycap material, case construction, plate stiffness, and how hard you type all reshape the result. Two clicky boards in the same room can sound like different instruments.

Finally, hot-swap does not mean universal. A replacement switch has to match the PCB’s pin count, plate clearance, mounting style, and LED design. Gateron Melodic is a five-pin switch with SMD LED support — it wants a compatible hot-swappable PCB or soldering, and it won’t drop into every board.

Then there’s the noise question, and it deserves a straight answer. Clicky switches are loud on purpose. No setting removes the click, and microphone noise suppression only reduces what other people on the call hear. If you share an office, a bedroom wall, or a call schedule, that matters before you buy. If you’ve already accepted the trade-off and want to cut the cable, this roundup of tested clicky wireless keyboards covers the models that keep the snap without the tangle.

For the switch mechanics themselves, CHERRY’s MX2A Blue specifications lay out the actuation, travel, and contact design in detail.

One last habit worth keeping: type with normal force. Hammering the keys adds noise and fatigue without making the switch respond any faster, and it’s the easiest way to make a clicky keyboard unwelcome in a shared space.
