KEYSWITCH STRUCTURE

摘要

A keyswitch structure includes a base, a keycap, at least one lift mechanism, a link, and a restoration mechanism. The lift mechanism is connected to and between the base and the keycap. The link is moveably on the base. The restoration mechanism is disposed on the link and the base and can generate a restoration force. When the keycap is pressed down by a user to move toward the base, a sliding portion of the lift mechanism slides on the base to drive the link to move relative to the base. Further, when the pressing on the keycap by the user is eliminated, the restoration force urges the link to move to drive the sliding portion to slide reversely, so that the keycap moves away from the base.

1. A keyswitch structure comprising:
a base comprising a first magnetic portion; a keycap disposed above the base; a first lift mechanism connected to and between the base and the keycap, the first lift mechanism comprising a first supporting part and a second supporting part, the first lift mechanism and the keycap being connected by a first connection portion, the first supporting part having a first sliding portion slidably disposed on the base, the keycap being capable of moving up and down relative to the base through the first lift mechanism; and a link moveably disposed on the base, the link having a second magnetic portion, the second magnetic portion and the first magnetic portion generating a magnetic force therebetween; wherein when the keycap is pressed by a user so that the keycap moves toward the base through the first lift mechanism, the first sliding portion slides on the base in a sliding direction and drives the link to move relative to the base, and when the pressing on the keycap by the user is eliminated, the magnetic force urges the link to move to drive the first sliding portion to slide in a direction opposite to the sliding direction so that the keycap moves away from the base.
