Over at CES 2018, Cooler Master has its new MasterKeys MK851 keyboard on display. This peripheral distinguishes itself from the pack by offering optical switches for the WASD keys and four more keys. It's not the first keyboard to offer this but it's still a pretty unique feature. The optical switches are made by Aimpaid and they're pressure sensitive, so they operate more like a gas pedal rather than an on/off switch. The other keys on the MK851 feature Cherry MX Red switches.
"Traditional keyboards act like an on/off switch where keys are actuated then released. With Aimpad activated, the MK851 keys function like a gas pedal. The result is more control, especially when driving vehicles, making slight adjustments, or course corrections without having to continuously tap keys. Instead, press down slightly for smooth control."
Other special features include two Precision Wheels, which can be used to control various things like audio volume or LED settings.
Cooler Master says the MasterKeys MK851 will ship in Q2 or Q3 of this year. Furthermore, the company will also offer a MK850 variant. That version will not have the pressure-sensitive WASD keys but will be offered in Cherry MX Blue and Brown switch types.
