Hall Effect keyboards use magnetic sensors to detect key depth rather than physical contact, enabling features impossible with traditional switches. Rapid Trigger allows keys to reset and re-actuate at any point during travel, dramatically reducing response time in competitive gaming. Adjustable actuation lets users set the exact depth at which a key registers, from a hair trigger 0.1mm to a deliberate 4.0mm. Multi-point actuation enables different actions at different depths on the same key. The Wooting 80HE remains the benchmark, but competitors like Corsair Vanguard 96 and Keychron Q1 HE are bringing this technology to broader audiences.
