Geon Raptor HE ~$9.00 / 10

Hall Effect switches like the Geon Raptor HE represent a fundamentally different approach to switch design. Rather than using physical contact between metal components to register a keypress, Hall Effect switches detect the magnetic field of a magnet embedded in the stem. As the stem moves down, its magnetic field changes relative to a Hall Effect sensor on the PCB, which converts this field change into position data. The result is a switch that can report analog position — not just on/off — and has no mechanical wear point.

The practical implications are significant for gaming. With a compatible Hall Effect keyboard like the Wooting 60HE or Geon F1-8K, the actuation point can be set anywhere from 0.1mm to 4.0mm through software. Want a 0.5mm hair-trigger for FPS games? Set it. Prefer 2.5mm for typing accuracy? Done. This configurability is impossible with traditional mechanical switches where actuation is fixed by the physical mechanism.

Analog input support is the other transformative feature. In compatible games, Hall Effect switches report partial travel as analog input — like a joystick axis. A key pressed halfway down can represent "walk" while fully pressed represents "run," without needing a separate thumbstick. This feature is still emerging in game support but represents a genuine evolution in keyboard gaming capability.

Feel-wise, Hall Effect switches are smooth throughout travel with no distinct bump or click. The magnetic force provides a spring-like return force that can be adjusted through stem design. The Raptor HE specifically is designed to feel similar to a medium-weight linear — smooth, consistent, and predictable. Without the physical contact of traditional switches, there is no scratchiness and no need for lubing.

Compatibility is the main limitation. Hall Effect switches require keyboards with Hall Effect sensing PCBs — standard MX hot-swap keyboards cannot use them. This means building or buying a specifically compatible board. The technology is newer and board options are more limited than traditional MX designs, though the ecosystem is growing rapidly as the gaming community recognizes the performance advantages.
