Keyboard keycaps are plastic cap-shaped components installed on top of keyboard keys, directly in contact with the fingers. Their main functions include:
Identifying key functions: Letters, numbers, or symbols are printed on the surface to indicate the function of each key.
Affecting typing feel: The material, height, and shape directly affect the tactile feel and comfort when typing.
Determining keyboard appearance: Personalized aesthetic expression is achieved through color, patterns, and manufacturing processes.
Material determines durability and feel:
ABS: Smooth feel, rich colors, but prone to "oiling" (surface becomes shiny after wear).
PBT: Wear-resistant, oil-resistant, dry to the touch, but difficult to process and has limited color options.
POM: Self-lubricating, silky smooth feel, extremely wear-resistant, but limited color options (mostly black) and high cost.
