Alps-inspired mid-weight tactile whose pronounced POM stem step front-loads the bump event, producing a sharp snap with quick decay rather than the plateau or drawn-out crossing of conventional MX tactiles. Polycarbonate top over nylon bottom; factory-lubed on rail contacts only, leaving the bump face dry to preserve tactile sharpness. 5-pin PCB mount.
Gazzew designs, Outemu molds, and a plastic softer than nylon does the rest. Every Boba is the same chamber with something deliberately left out — and the pattern of subtractions is the whole family tree.
thock has already reached for the buckling-spring snap twice — once to describe a Topre dome, once to describe a click-bar's sharpness — without ever explaining what a buckling spring actually is. The mechanism predates both, and it is stranger and more mechanically honest than either.
The Durock T1 keeps turning up as the comparison point in other switches' deep-dives — the reference a reviewer reaches for when a bump needs to read as heavy and serious. It has never had its own.
Same housing, same bump position — the U4T's whole personality comes down to what Gazzew left out. Pull the dampening pads from a Boba U4 and the bottom-out stops being polite.
Gateron's Lanes draws its DNA from the Alps SKCM Orange — one of the most loved tactile mechanisms of the 1980s — and arrived in June 2026 with enough community conviction to sell out on first drop.
An optical switch replaces the metal contact with a beam of light. That one change eliminates contact bounce entirely, reshapes the latency math, and is why some optical boards can offer per-key actuation at 0.1mm granularity. The mechanism is simpler than the marketing makes it sound.
Cherry's MX2A landed in 2023 with a real engineering update — factory lube, tighter tolerances, the same 100M-press lifespan. The reason the discourse cooled isn't that the switch failed; it's that the enthusiast slot it aimed at was already claimed by the time it arrived.
Two years ago HMX was a name on a vendor page nobody pronounced confidently. In W19, the Cloud sat second among switches on our tracker and landed in half the $120 prebuilts the scene argues about. The rise wasn't an accident.
A Hall-effect switch is not a faster MX switch. It is a different sensing lineage — a magnet in the stem, a sensor on the PCB, and an analog voltage where contact closure used to be. The features the marketing pages lead with all unwind from that one architectural fact.
