Abstract: A key structure, including a keycap, a scissor component, an elastomer, an optical switch, a shading portion, and a circuit board, is provided. The scissor component is formed of a first and a second supporter. The circuit board has two first and two second limiting units. The keycap has two third and two fourth limiting units. The first supporter is rotatably or slidably connected to the first and the third limiting units. The second supporter is rotatably or slidably connected to the second and the fourth limiting units. The keycap is disposed on the circuit board through the scissor component. The elastomer is interposed between the circuit board and the keycap. The optical switch includes an emitter and a receiver. The shading portion is disposed on the first or the second supporter to block a light signal transmitted between the emitter and the receiver.

Abstract: A key structure includes a key cap, a bridge assembly, a first supporting part, a second supporting part, an attractable element and a magnet. The bridge assembly includes first and second hinge parts. One end of the first hinge part has a first link bar, and the other end has a first pivot coupling portion and a first shaft having a first connecting portion. One end of the second hinge part has a second link bar, and the other end has a second pivot coupling portion and a second shaft having a second connecting portion coupled to the first connecting portion. When the magnet under a first attractive position, the first end of the attractable element is attracted to the first attractive position. When the magnet under a second attractive position, the second end of the attractable element is attracted to the second attractive position.

Abstract: A keyboard including a substrate and a key structure is provided. The key structure is disposed on the substrate and includes a keycap, an antenna, and a sensor. The keycap is disposed on the substrate, and a length of the keycap is greater than a width of the keycap. The antenna is disposed on a back surface of the keycap facing toward the substrate. The sensor is disposed below the keycap and is electrically connected with the antenna.
