Magnets have been replacing potentiometers in a variety of places for a while now, especially as Hall effect and TMR joysticks have started popping up in fancy game controllers. Now magnetic switches are becoming more common in mice and mechanical keyboards, and Will has spent some time with new products in both of those categories, so we figured it was a good time to lay out how these kinds of switches work, how resistant to wear and electrical "bouncing" they are, what the heck a transducer is, whether there's quantum mechanics involved or not, and what effect these new switches are going to have on the input devices of the future.
