The Translation: A “hot-swappable” keyboard has special sockets that let you pull out the mechanical switches and push new ones in using just a pair of tweezers. No soldering iron required.
Use It In a Sentence: “I wasn’t sure if I would like loud, clicky keys, so I made sure to buy a hot-swappable board so I can easily change them later.”
Why You Care: If you are a beginner, you absolutely must buy a hot-swappable keyboard. In the old days, if a single key broke or you wanted to change how the board sounded, you had to melt metal solder with a hot iron to remove the switch. Hot-swappable boards make customizing your keyboard as easy as plugging in Lego bricks.
