3.3 Hall Effect Magnetic Switches and Rapid Trigger
The K556 HE utilizes Hall Effect magnetic switches for hyper-fast actuation and extended lifespan. The Rapid Trigger technology, enabled via software, allows for precise actuation point adjustment between 0.1mm and 3.4mm. This dynamic activation/deactivation feature is crucial for competitive gaming, enabling quicker key presses and resets.
