Linear switches have the simplest operation, moving straight up and down without any additional tactile feedback or loud clicking noise – we’ll come to these more complicated switches later on. There are two common types of linear switches – Black and Red.
Cherry MX Black switches were introduced in 1984, making them one of the older Cherry switches. They have a medium to high actuation force, at 60 cN (gr), which means they are the stiffest of the four most common Cherry switches. The stronger spring also means that they rebound faster, meaning they can be actuated quite quickly given enough force – although you may also find fatigue becomes more of a factor than with other switches. May suitable for needs of double click with it's fast rebound.
Cherry MX Red switches are the most silent of all Cherry MX switches (because it's linear). They have a low actuation force, at 45 cN (gr) – tied with Brown for the lowest of the four most common switches. Red switches have been marketed as a gaming switch, with the light weighting allowing for more rapid actuation, and have become increasingly common in gaming keyboards.
Tactile, non-clicky switches
Tactile switches provide, as the name suggests, additional tactile feedback as the key actuates. As you press the key down, there is a noticeable bump which lets you know that your key press has been registered.
The most popular type of tactile, non-clicky switch is the Cherry MX Brown. This switch was introduced in 1994 as a special ‘ergo soft’ switch, but quickly became one of the most popular switches. It has 45 cN (gr) actuation force. Brown switches are good middle-of-the-road option appropriate for both typing and gaming. They are also ideal for typing in office environments, where a clicky switch might annoy some.
Tactile, clicky switches
The Cherry MX Blue is the most common clicky switch, and was first made available in Filco keyboards in 2007. Blue switches are favoured by typists due to their tactile bump and audible click, but can be less suitable for gaming as the weighting is relatively high – 50 cN – and it is a bit harder to double tap, as the release point is above the actuation point. Blue switches are noticeably louder than other mechanical switches, which are already louder than rubber domes, so these switches can be a bit disruptive in close working conditions.
