GATERON Magnetic Jade Series Switches (Jade Pro Dual-SMD, 70) Review (2026)

How magnetic Hall effect switches work here

The Jade Pro is a linear Hall effect switch that reads the position of a magnet in the stem rather than closing a metal contact, which is what allows features like rapid trigger and adjustable actuation points on supporting keyboards. GATERON's own product page lists an initial actuation force of about 36 grams-force, rising to roughly 50 grams-force at bottom-out, with 3.5mm of total travel. Because actuation depends on magnetic flux rather than a fixed mechanical point, the pre-travel distance can be set freely in firmware on boards that support it, letting a user dial in a lighter, faster trigger for gaming or a heavier one for typing.

Dual-SMD lighting design

The Dual-SMD designation refers to two surface-mounted LED positions supported by the switch housing instead of one, which GATERON markets as giving brighter, more evenly spread per-key RGB lighting on boards wired for it. This is a newer revision of the Jade Pro line, and GATERON's spec sheet lists an initial magnetic flux of about 120 Gauss and a bottom-out flux near 700 Gauss on a 1.2mm PCB, values that need to match what a given hall effect board and its firmware expect. Buyers should confirm their keyboard's PCB is calibrated for this flux range before ordering, since not every hall effect board handles every switch revision identically.

Pack size and coverage

This listing is the 70-piece pack, which is enough for a compact 65 percent or 60 percent layout hall effect keyboard, the size range most rapid trigger and gaming-focused magnetic boards ship in. It will not stretch to a tenkeyless or full-size board without ordering a second pack, so builders should count their exact key total before buying. The switches arrive pre-lubed from the factory, according to GATERON, which should help keep the linear travel smooth without requiring a separate lube step before installation. GATERON also states the pack ships with a 20mm customized spring tuned for the magnetic stem, and the housing keeps the same plate-mount footprint as earlier Jade switches, so builders upgrading from a previous Jade revision should not need to change their plate or case to fit this pack.

Cost and where it fits

Magnetic Hall effect switches cost more per unit than standard mechanical switches because of the added sensor technology and the PCBs built to support them, and this pack is no exception, sitting at a premium price point compared with basic linear switches. That cost buys features unavailable on standard boards, chiefly adjustable actuation and rapid trigger, both of which matter most for competitive gaming where a faster or more consistent keypress can matter. Typists who do not need those features, or who are not using a hall effect board in the first place, will get more value from a standard mechanical switch instead.

Who should buy this pack

This pack is aimed at someone building or upgrading a compact hall effect keyboard who wants the newer dual-SMD lighting revision and does not mind checking PCB compatibility first. It suits gamers who want rapid trigger and adjustable actuation more than typists chasing a specific tactile or clicky feel, since the Jade Pro is a linear-only switch. Anyone without a compatible magnetic PCB, or building a standard mechanical keyboard, should skip this pack, since these switches will not function outside a Hall effect system built to read them. Builders who already own a hall effect board with a known-compatible flux range and want the newer dual-SMD lighting upgrade get the most value from this specific pack over an older single-LED Jade revision.
