Quick Summary

The Kailh Blue is the budget clicky everyone tries at least once: a ~50g click-jacket switch with a sharp, bright click and a genuinely loud voice. It is built for typists who want tactile-and-audible feedback, not for gamers chasing fast resets or anyone sharing a room. As a cheap Cherry MX Blue stand-in, it does the job and then some.

Specs and Feel

You get a 2.0mm pre-travel and a full 4.00mm total travel, with actuation around 50g (±15g unit to unit). The nylon top and bottom housings and POM stem keep things firm and clacky rather than refined. The click comes from a separate click jacket on the stem, so the tactile bump and the audible click fire together: that is what makes it feel crisp and report so loudly. Smoothness is middling by enthusiast standards, but at this price the appeal is the snap, not glassy travel. Stem wobble is average for a non-BOX Kailh.

Tuning

Resist the urge to lube the slider: oil on the click jacket mutes the very thing you bought it for. If you get spring ping, a careful dab of grease on the spring ends helps without touching the click mechanism. Otherwise this is a stock-and-go switch; thocky keycaps or a foamed case will tame some of the high-pitched ring if it is too sharp for you.

Verdict

Buy the Kailh Blue if you want maximum click for minimum money and you type somewhere nobody will file a complaint. It is louder and sharper than a tactile Box Brown and far brighter than a refined clicky like the Box Jade, which sounds deeper and more controlled. Skip it for shared spaces, late-night sessions, or competitive gaming.

Frequently asked

How loud is the Kailh Blue?

Very loud. This is one of the most boisterous clicky switches around: fun at home, but a fast way to annoy office or call-mates.

Is it a good Cherry MX Blue alternative?

Yes. At roughly 50g with a 2.0mm pre-travel and a classic click-jacket mechanism, it covers the same ground as an MX Blue for a fraction of the cost.

Should I lube it?

Leave clicky switches mostly alone — lubing the slider kills the click. You can lightly grease the springs to quiet any ping, but keep oil off the click jacket.
