TMR keyboards work nothing like the one you’re typing on

TMR switches, short for Tunnel Magnetoresistance, are regarded as one of the most exciting developments in mechanical keyboards. They do not operate via conventional contact points, nor do they use traditional Hall-effect sensors.

Instead, they measure changes in magnetic resistance, doing so with significantly greater precision. This results in a more finely controllable actuation, opening up new possibilities for both frequent typists and gamers. But what does this mean in practical terms...
