A4Tech is a Taiwanese company whose ?Bloody? gaming division was launched in 2012. Bloody produces gaming keyboards and mice using a unique switch technology: rather than metal contact points closing an electrical circuit when a key is pressed, Bloody's mechanical switches use infrared LEDS and photosensors, which Bloody claims provides faster key response and a more reliable and durable switch.
