Cherry MX switches are mechanical switches used in many mechanical keyboards. They were first developed by the Cherry Corporation in the 1980s and have since become a popular choice for their durability, tactile feedback, and audible click. They use a spring-loaded design, where each switch has a spring inside that provides resistance when the key is pressed. This resistance, or actuation force, is what gives the user feedback when a key press is registered.

Cherry MX switches come in several different variations, each with their own unique characteristics. The most common types are the Cherry MX Red, Brown, Blue, Black, Silver and Green.

Cherry MX Red switches have a linear actuation, meaning the resistance is consistent throughout the key press. They have a low actuation force of 45g and no tactile feedback. They are popular for gaming and fast typing.

Cherry MX Brown switches have a tactile actuation, meaning there is a small bump when the key press is registered. They have a moderate actuation force of 55g and are popular for general typing and gaming.

Cherry MX Blue switches have a tactile actuation and an audible click when the key press is registered. They have a high actuation force of 60g and are popular for typing but not recommended for gaming.

Cherry MX Black switches have a linear actuation, but higher actuation force of 60g. They are popular for gaming and fast typing.

Cherry MX Silver switches have linear actuation, actuation force of 45g and are popular for fast typing and gaming.

Cherry MX Green switches have a tactile actuation and an audible click when the key press is registered, they have a high actuation force of 80g and are similar to the Cherry MX Blue switches but with a higher actuation force.

In addition to the different switch types, Cherry MX switches also come in different colors, which indicate the switch's actuation force and tactile feedback. The color of the stem of the switch is usually used to identify the switch, Red for linear, Brown for tactile, Blue for tactile and clicky, Black for linear, Silver for linear and Green for tactile and clicky.
