Quick Summary
The BSUN Mozzarella Cheese is a factory-lubed tactile switch designed by Keys in Studio and built by BSUN, aimed at people who want a rounded mid-tactile feel without committing to a heavy bump. It pairs a gentle tactile event with a neutral, poppy sound signature and a short overall travel. If you like tactility that informs rather than fights you, it’s an easy switch to live with.
Specs and Feel
This is a mid-leaning tactile bump, present and clearly felt but never sharp or jarring. Pre-travel sits around 2.3mm with a total travel of roughly 3.3mm, so the keystroke feels noticeably shorter and snappier than a standard 4mm MX switch, and the 55g bottom-out keeps it in comfortable medium-weight territory for long sessions. The POK top and POM bottom housing over an LY stem give it a neutral, mild-toned acoustic that leans poppy and a touch sharp depending on the build. The 20mm single-stage spring delivers a clean return, and the factory lube keeps stem travel smooth with no meaningful scratch through the bump. Wobble is well controlled for a switch in this price bracket.
Tuning
These come pre-lubed, so most builders can run them stock and be happy. If you want to nudge the sound deeper or tame any sharpness, a set of films and a slightly fuller spring would help, but it’s optional rather than necessary. Save the effort for switches that actually need it.
Verdict
Buy the Mozzarella Cheese if you want an approachable, well-mannered tactile that doesn’t demand a tuning session. The mild bump, short travel and neutral-poppy profile make it a comfortable everyday pick rather than a statement switch. Tactile purists chasing a heavy, dramatic snap should look elsewhere, but for a balanced, low-fuss build this is an easy recommendation.
Frequently asked
Are BSUN Mozzarella Cheese switches lubed from the factory?
Yes, they ship factory-lubed. That handles most of the scratch, so they're a solid drop-in if you don't want to hand-lube a full board.
How heavy is the tactile bump?
It's a mid-leaning bump, not aggressive. Combined with the 55g bottom-out it reads as a gentle, rounded tactile rather than a sharp snap.
What's the travel like compared to a standard MX switch?
Travel is short: about 2.3mm to the bump and 3.3mm total, versus the usual 4mm. Expect a slightly quicker, more responsive bottom-out.
