Abstract: A keyboard includes a plurality of key modules. Each key module includes a baseplate, a circuit membrane disposed on the baseplate, a metal dome disposed on the circuit membrane, an elastic member disposed on the metal dome, and a keycap. The elastic member and the linkage member are configured to be a movable switch mechanism. The circuit membrane has a conductive circuit. The metal dome has an opening corresponding to the conductive circuit of the circuit membrane. A trigger portion protrudes from an underside of the elastic member. When the keycap is pressed, the trigger portion passes through the opening of the metal dome, and moves downwards to abut against the conductive circuit to induce a conducting signal. The movable switch mechanism can be made by a double injection molding method.

Abstract: A key structure includes a supporting board, a base board, a pre-stressing force applying assembly, a key cap, a pivot assembly, an attractable element and a magnetic element. The pre-stressing force applying assembly is connected to the supporting board or the base board. When the magnetic element is under the first attractive position, the first end of the attractable element is attracted by the magnetic force and moved to the first attractive position, and the pre-stressing force applying assembly generates a first pre-stressing force; when the magnetic element is under the second attractive position, the second end of the attractable element is attracted by the magnetic force and moved to the second attractive position, and the pre-stressing force applying assembly generates a second pre-stressing force. The first pre-stressing force or the second pre-stressing force reduces the resistance during the sliding of the base board or the supporting board.

Abstract: A key structure comprises a bottom board, a key cap and two first balance plates. The two first balance plates are plate shaped, disposed between the bottom board and the key cap, and symmetric to each other. An upper end of each of the two first balance plates is connected to the key cap. A lower end of each of the two first balance plates is connected to the bottom board. Thereby, a key structure is formed which provides a normal tactile feel while saving space, thereby achieving a slim design.
