▎ 摘　　要

NOVELTY - Key structure 100E comprises a first electrode, a key cap arranged on the first electrode and a restoration member arranged between the key cap and the first electrode, where the key cap or the restoration member has a second electrode, and a sensing signal is generated by the second electrode with a movement of the key cap or the restoration member relative to the first electrode. USE - Key structure for a keyboard utilized to assist users in operating or inputting signals to a personal desktop computer, a notebook computer or a tablet computer and other electronic products equipped with a keyboard or an external keyboard. ADVANTAGE - The key structure enhances operating sensitivity of the keyboard and reduces the possibility of false triggering, thus additional conductive member is not required in the key structure to trigger a switch and the mechanism is simplified. DESCRIPTION OF DRAWING(S) - The drawing shows schematic cross-sectional view of a key structure.
