Keyboard switches are the mechanisms beneath each key on a keyboard that register a keystroke. They come in various types, primarily categorized into mechanical, membrane, and scissor switches. Mechanical switches are known for their durability and tactile feedback, while membrane switches are quieter and often found in budget keyboards. Scissor switches are commonly used in laptops for a low-profile design. Each type of switch has unique characteristics, such as actuation force and travel distance, affecting typing experience and performance. Users often choose switches based on personal preference, typing style, and intended use, whether for gaming, typing, or general use.
