Quick Summary
The Gateron Jupiter Banana 59g is a medium-weight tactile switch built around a rounded, pronounced bump and a shortened 3.4mm travel. It pairs a POM stem with a polycarbonate top and nylon bottom housing, comes factory lubed, and uses a two-stage spring for a snappier return. If you want a tactile that feels deliberate and a little punchy without crossing into heavy clack territory, this is an easy recommendation.
Specs and Feel
This is a clearly defined tactile, not a soft mushy bump. The 59g spring lands in comfortable everyday territory, while the tactility itself feels stronger than the weight implies. The bump is rounded but assertive, with a clean release into the keystroke. The headline trait is the 3.4mm total travel: bottom-out arrives noticeably sooner than a standard switch, which gives the whole press a brisk, controlled cadence that faster typists tend to appreciate.
Smoothness is good for a stock tactile thanks to the factory lube, with only faint scratch on the upstroke if you go hunting for it. Stem wobble is modest and well within normal for a Gateron, so legends stay stable and shine-through caps line up cleanly over the LED diffuser. The PC-and-nylon housing gives the sound a slightly deeper, rounder pop rather than a sharp tactile snap.
Tuning
There is little obligatory work here; the factory lube does most of the job. If you want to push it further, switch films will tighten housing rattle and a thin manual lube pass on the rails can quiet the upstroke, but neither is necessary to enjoy these stock.
Verdict
A confident, well-rounded tactile that earns a pick for most builds. The shortened travel and snappy two-stage spring make it especially appealing if you type quickly and want the bump to land early, and the medium weight keeps it comfortable over long sessions. Skip it only if you specifically want a heavy tactile or full 4.0mm throw. Otherwise the Jupiter Banana 59g is one of the more satisfying stock tactiles in its class.
Frequently asked
Is the Gateron Jupiter Banana a heavy tactile switch?
Not really. At 59g it sits in the medium range, heavier than a stock Brown but well short of a true heavy tactile. The bump feels more pronounced than the spring weight alone suggests, so it reads as confident rather than fatiguing for all-day typing.
Do the Jupiter Bananas need lubing out of the box?
They come factory lubed and are perfectly usable stock. A light hand-lube and switch films are optional refinements rather than fixes, mostly tightening housing wobble and smoothing the return.
What is the total travel on the Jupiter Banana 59g?
Total travel is a shortened 3.4mm rather than the MX-standard 4.0mm, which shaves the bottom-out and suits faster typists who want the bump to land sooner.
