Abstract
A key includes a substrate, a keycap, a connection component, and protruding structures. The connection component includes a first connection member and a second connection member, and the first connection member and the second connection member are between the substrate and the keycap. The protruding structures are disposed on the upper surface of the first connection member and disposed on the upper surface of the second connection member. When the keycap is pressed to a pressed position, the protruding structures on the first connection member and on the second connection member abut against the bottom surface of the keycap, so that a gap is formed between the keycap and the connection component. Therefore, the bottom surface of the keycap does not contact the upper surface of the first connection member and the upper surface of the second connection member so as to prevent from generating keystroke noises.
