Product Description

The Bloody Hand

Bringing the functionality of a full-sized keyboard with N-key rollover and a 1,000Hz report rate, A4 Tech introduces the Bloody B640 Keyboard, built with optical switches to give you the fastest gaming experience possible. Get into the mood with red LED backlighting and feel the caress of textured, grooved, silicon WASD keys so you never lose your place as your fingers fly across the keys.

This keyboard uses a new innovative switch that was recently invented by A4Tech and is Cherry MX Compatible

Cut the Chatter

You’ve moved on from your rubber dome keyboard and jumped into the smooth existence that is mechanical keyboards, but one of your keys keeps double tapping. It’s not your technique that’s suffering, but a phenomenon called key chattering. Most mechanical switches work by metal-on-metal contact, but their flexibility can cause them to bounce and be registered twice. The Bloody B640 keyboard’s optical switches eliminate that problem by removing any physical switch contact, keeping you at a 100% hit rate.

Deactivate a Laser with a Click

Instead of touching two pieces of metal together, each key is outfitted with an optical sensor and light source which registers the keystroke at the speed of light. Every key press is registered as soon as the light beam is interrupted allowing for unparalleled accuracy and speed. Relying purely on the life of led instead of any physical components you can safely click away to your hearts delight without worrying about any key failure.
