A coral sparkline climbing steadily across five data points toward a flat warm-grey ceiling line near the top of the frame, the gap between the two narrowing from left to right, plotted beside a muted cross-section motif of a magnet over a sensor pad, with a small warm-bronze theme dot in the upper-right margin.

TMR is closing the gap on Hall-effect. It hasn't caught it.

TMR switches have climbed every week on thock's trend tracker from W38 through W42 — 55, 63, 71, 85, 90. That's the second-highest score on this week's board, and the gap behind Hall-effect's ceiling has gone from 42 points to 10 in five readings.

What a TMR sensor is actually measuring under a magnetic switch

Keychron's Q16 HE 8K and Cherry's XTRFY TMR boards get covered as a new switch generation. The real change sits a few millimeters below the magnet — a tunnel junction reading field strength through resistance instead of voltage, with a noise floor low enough to matter at the shallow end of the stroke.

Keychron launches Q16 HE 8K with ceramic-TMR magnetic switches

Keychron's Q-series just picked up a Kickstarter campaign, a ceramic-housed TMR magnetic switch, and an 8000Hz polling claim in one launch. It's the brand's first bet on tunnel-magnetoresistance sensing rather than the Hall-effect tech it already made the category default.

Cherry bets on magnetic: the XTRFY pivot

Cherry's mainline MX switches have spent the better part of a year losing ground on the tracker. On July 3, 2026, Cherry's gaming sub-brand XTRFY answered not with another MX revision but with a magnetic-sensing switch — and gave the parent brand its first positive tracker signal in months.

Nova Socket: Keychron's bet on not choosing a switch technology

A single hot-swap socket that accepts a standard mechanical switch or a TMR magnetic switch, decided per key, is a strange thing for a mainstream prebuilt brand to ship. It's also exactly the move Keychron has been building toward all year.
