Keyboard Basics

Basic Terms

• Keycap: [Plastic outer covering][keycaps] of a particular key typically inscribed with the character that gets sent to the computer when struck.
• PCB: Printed Circuit Board (really, just a circuit board), which registers keystrokes and sends them to the computer.
• Switch: underlying mechanism that the keycap covers, and in some way creates contact with the PCB to let it know that a keystroke needs
