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. Benchmark Reviews checks out the Bloody B840 LK Optic Mechanical Gaming Keyboard, equipped with next-generation "clicky" optical key switches.
