Mechanical keyboards are mainly classified according to mechanical switches. The mainstream can be divided into red switches, black switches, green switches and brown switches according to color. They mainly differ in the initial pressure, triggering pressure and the size of the sound produced by the knocking itself. Different axes are suitable for different people and scenarios. Logitech, Rapoo, and Razer are all good mechanical keyboard brands. The following is a detailed introduction:

1. Red axis Red Switch, this is a linear axis with a trigger key stroke of 2.0mm, an initial pressure of 30cN, and a trigger pressure of 45 to 15cN. The reason why the red axis is said to be a linear axis is that it has no sense of paragraphs when pressed, and is straight down and straight up. At the same time, the trigger pressure is smaller, which makes it require lighter force when pressed, making it suitable for long-term coding or operations. Keyboard person. Although the sound of the red switch itself is not too loud, Cherry has launched a special silent version for it. If you are not so obsessed with the clicking sound of mechanical keyboards, the red axis is a more balanced choice;

2. Black Switch Black Switch, this is also a linear axis with a trigger key travel of 2.0mm , initial pressure 30cN, trigger pressure 60 ± 20cN. The black axis, like the red axis, is a linear axis, but the trigger pressure is larger. It is suitable for people who like the keyboard to feel heavier and need to press hard. However, for most people, long-term use may cause finger fatigue. The number of users of the black switch is relatively small, mainly because long-term use can easily cause fatigue, so it is more difficult to use;

3. The blue switch Blue Switch is a segmented switch with a trigger key travel of 2.2mm. Pressure 25cN, trigger pressure 50 ± 15cN, step pressure 60 ± 15cN, step stroke 1.75mm. Although the actuation key travel is longer, the initial pressure is even smaller than the red switch, so it is easier to hit. However, considering that the green switch has a sense of passage when pressed, it will make a ticking sound, which is similar to a ballpoint pen pressing a switch, so the sound will be louder;

4. Brown Switch, this is also Step shaft body, trigger key travel 2.0mm, initial pressure 30cN, trigger pressure 45 ± 20cN, step pressure 55 ± 25cN, step stroke 1.25mm. The brown switch is the switch closest to the membrane keyboard, because although there are steps, it is not obvious, and the trigger pressure is also lighter. If you are just transitioning from the membrane keyboard, it is more suitable to choose the brown switch. At the same time, the less obvious sense of paragraphs also makes the sound when pressed smaller than that of the blue axis.
