Other keyboards have a mechanical-style feel but are built on different mechanisms entirely. The hot new trend in gaming-focused keyboards, for example, is Hall effect switches, which use tiny magnets to register keystrokes and let you customize the sensitivity of each press. Optical switches, meanwhile, offer similar functionality by replacing the physical contact point of a typical mechanical switch with a beam of infrared light. More recently, we’ve seen a couple keyboards launch with inductive switches, which can work like magnetic switches but use inductive coils in the keyboard’s printed circuit board (PCB) to cater to all switches collectively and don’t require a sensor for each individual switch. We touch on a couple of magnetic-switch keyboards in our picks below, but for a fuller breakdown of this sort of tech, we recommend you check out our dedicated buying guide to the best gaming keyboards.
