These days most of the gaming keyboards use Cherry MX keys. These are manufactured by ZF Electronics or formerly known as Cherry Corporation. What you need to realise is that different switches provide different feel and feedbacks. They also require a different amount of pressure to be activated. In the case of Cherry MX keys, they are colour-coded. When you press the Cherry MX Blue keys, you will feel a small bump and clicking sound that is high pitched. Cherry MX Brown switches are stealthy. It makes less noise. But the Cherry MX Black keys are entirely different. There is no tactile and audio feedback. They are totally linear.
