Abstract

See full text

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.
