Quick Summary
The Gateron Magnetic Jade Ruby is a light linear built for Hall Effect boards, using a magnet and sensor instead of a physical metal contact to register each press. The payoff is an exceptionally smooth, bounce-free keystroke with none of the chatter that plagues worn mechanical contacts, plus the analog depth that magnetic switches unlock: adjustable actuation, rapid trigger, and the like. It is a clear pick for anyone building a magnetic gaming or analog board who wants a light, fast switch.
Specs and Feel
This is a true linear: no bump, no click, just a clean downstroke. Force is light, sitting around 36g at actuation and roughly 50g at the bottom over a 3.5mm total travel, so it presses with very little resistance and resets quickly. A customized spring keeps that light weighting consistent through the stroke rather than mushing out near the end. The headline trait is smoothness: because actuation is magnetic, there is no leaf to drag across, so the travel reads as glassy with no scratch and no contact bounce. Stem wobble is well controlled for a stock switch, and the overall feel is composed enough that the light weight never turns vague.
Tuning
Leave it stock. Magnetic switches depend on precise stem-and-magnet positioning, and hand lubing risks gumming the sensing tolerances for little gain on an already-smooth stem. Films are unnecessary here too. The housing is consistent enough that the upside is marginal. If anything, spend your effort calibrating actuation in your board’s software rather than reaching for tools.
Verdict
If you own or are building a Hall Effect board, the Jade Ruby is an easy recommendation: light, fast, smooth, and chatter-free, with the analog flexibility that makes magnetic switches worth the platform lock-in. The one caveat is exactly that lock-in: it will not work in a standard mechanical keyboard, and even some magnetic PCBs may not play nicely, so verify compatibility first. For magnetic-board owners who want a light linear, it is a buy.
Frequently asked
Does the Gateron Magnetic Jade Ruby work in a regular mechanical keyboard?
No. It is a Hall Effect switch that senses position through a magnet rather than metal contacts, so it only works on dedicated magnetic / analog PCBs. Even among magnetic boards, compatibility varies, so confirm your PCB supports Gateron's magnetic switches before buying.
How heavy is the Jade Ruby?
It is on the light side, roughly 36g at the actuation point and about 50g at the bottom, paired with a 3.5mm total travel. That makes it well suited to fast gaming presses and long typing sessions without fatigue.
Do magnetic switches need lubing?
Generally no. With no metal leaf to overcome and a smooth stem, the Jade Ruby feels clean out of the box, and many magnetic boards rely on tight stem-to-magnet tolerances that hand lubing can disturb.
