Red switches are the most popular switches in the market. They are used in all keyboards, including gaming keyboards, mechanical keyboards, and even regular office keyboards.
There are many benefits of using red switches. They offer great tactile feedback that is not too heavy or too light, and they have a good actuation force. However, red switches also have some disadvantages, such as their high actuation force and high noise level.
You can find red switches at various prices depending on what type of keyboard you are buying them for. For example, a gaming keyboard with a red switch can cost up to $200, while a regular office keyboard might only cost $15-30 dollars for a set of keycaps with a red switch installed.
