Abstract

See full text

A key structure includes a base plate, a keycap and a connecting element. The connecting element includes a first frame and a second frame. The first frame is connected with the base plate and the keycap. The first frame includes a first linking part. The second frame is connected with the base plate and the keycap. The second frame includes a second linking part. The second linking part is contacted with the first linking part. When a depressing force from the user is applied to the keycap, the first frame is swung relative to the second frame. Moreover, in response to a friction between the first linking part and the second linking part, the keycap is correspondingly moved.
