anyone here knows about mechanical keyboards?
cherry blue brown what is this
Most cheap keyboards are membrane keyboards that use this thin sheet of plastic underneath the keys to input your keystroke and can sometimes be inaccurate or uncomfortable.
Mechanical keyboards instead have an individual switch for each key and in turn feel better to type on, and are much less likely to give any N-key rollover or inaccuracies.
Though most people go for mechanical keyboards for how it feels. It's simply a different experience using one compared to a membrane, you'll feel it almost as much as you can hear the difference. Hence the PCMR quote: "Once you go clack, you'll never go back."
As far as switches go, most users will use the "Cherry" switches which have a variety of colors and keystroke variance in terms of force and feedback.
Red: the most common for gaming is a linear switch, with no tactile feedback to it, so you won't "feel" the actuation point between when you press down and when it gets input on your computer, and is perhaps the most "light" of switches, so you won't have to press very hard to see your input, so it's really good for things where typing super fast or spamming keys is a necessity.
Black: is a lot like red, in that it's linear and you won't feel the actuation point of your keystroke, but you'll notice a significant increase in resistance to the amount of force for your keystrokes, so it feels much "heavier" to type, which is good for heavy-handed typists.
Brown: one of the few switches that are non-linear and introduce a tactile feedback upon your keystroke, but is relatively subtle. It's difficult to describe, but imagine very gently applying force to one key, and finally reaching a threshold in force that will bring the key all the way down to it's actuation and input point.
Which can be very satisfying for a general typing experience.
Blue: this is probably the most notorious switch and what most people think of when someone mentions mechanical keyboards, due to it's distinct "click" sound. This switch is also non-linear and gives tactile feedback, but will require slightly more force than a brown switch, which almost makes your keyboarding experience akin to that of a typewriter, which is kinda cool in it's own way.
Green: a relatively rare switch that tends to be mostly exclusive to razer's line of keyboards, these switches are a lot like blue in that they're tactile and clicky, but are significantly heavier in force necessary for their actuation point. Like nearly 50% heavier, at a whopping 80 grams of force to input your keystroke.
TL;DR
