The second major upgrade over the K60 is the use of mechanical switches under every key. Cherry MX red switches are being used in the K70, which are highly responsive, linear and soft switches, making them ideal for gaming. This keyboard also has n-key rollover, meaning that it does not matter which and how many keys you are pressing at once; they will all register.
Corsair also provides ten textured keys, designed to assist hardcore FPS gamers. These keycaps are red and their surface has greatly increased grip over standard keys.
The textured keycaps are also contoured, meaning that the W, A and D keys face towards the center key, S, the 1 key faces slightly rightwards and the 6 key leftwards.
Lighting is the third major upgrade of the K70 over the K60, as the latter had none. The K70 features red lighting LEDs under every single key. There are three brightness settings, not including the lighting-off option, as well as three basic modes: all keys, no keys and WASD plus 1 to 6 keys.
The multimedia buttons are backlit as well. A very interesting feature of the K70 however is that you can also set which keys you want lit and which not, allowing you to create your own patterns by simply holding down the lighting settings button.
