You can broadly separate mechanical switches into three buckets: linear, tactile and clicky. Linear switches feel smooth all the way down; they’re often popular with gamers since they tend to be light and fast to actuate. Tactile switches create a tangible “bump” sensation partway through a press; many people who spend all day typing prefer them because they clearly confirm each press without (always) being all that loud. Clicky switches are functionally similar to tactiles but make an audible “click” sound to match the bump; your coworkers may hate them, but others love the full-throated sense of feedback they provide. To be clear, just because two switches fall within the same bucket doesn’t mean they feel or sound exactly the same. The only way to figure out which switch works best for you is to do your research and, preferably, try some out for yourself.
