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 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. The first hinge part has a first pivot coupling portion and a first connecting portion. The second hinge part has a second pivot coupling portion and a second connecting portion, wherein the first and second connecting portions are connected on an axis, and the first and second hinge parts rotate with respect to the axis. The first and second supporting parts are coupled to two ends of the first and second pivot coupling portions, respectively. The attractable element is disposed on the second hinge part. The magnet is correspondingly located under the attractable element for providing a magnetic force, so that the attractable element is attracted and positioned by the magnetic force.
