Gateron Blacks operate linearly and offer an actuation point of 50 grams. Also linear, the 35-gram Clear switches are the fastest and easiest to press, while the Reds require 45 grams of force and Yellows require 50 grams of force. For those looking for a bit more tactile and clicky feedback, there are the Blues, which offer a 55-gram actuation point, and the super-heavy 80-gram Greens. The 45-gram Brown switches offer tactile but not clicky feedback. Each switch is good for up to 50 million keystrokes.
