Abstract

The invention relates to a key switch device which is characterized in that the key top part moves down smoothly without shaking when being pressed. The key switch device is also characterized in that when pressing the key switch (13), the upper and lower ends of the great connection component (15) of the key top part (13) can slide along the direction that parallels to the upper surface of base board (12), and the key top part (13) can move down directly; also, the left-right shake that the key top part (13) relatives to the great connection component (15) can be eliminated by pressing the right and left sides of the great connection component (15) set on the key top part (13).

Description

technical field [0001] The present invention relates to a key switch device, in particular to a connection type key switch device suitable for thin keyboards of notebook personal computers. Background technique [0002] Conventionally, for example, Patent Document 1 (Japanese Unexamined Patent Publication No. 2001-283675) and the like disclose a link type key switch. The key switch device disclosed in this Patent Document 1 generally has the structure shown in FIG. 6 . In the key switch device shown in FIG. 6, a rubber spring 3 is installed between a base plate 1 and a key top 2, and the key top 2 is formed so as to be able to move freely. Furthermore, between the base plate 1 and the key top 2, there are provided a small connecting member 4 and a large connecting member 5 which are not in contact with each other, and which are perpendicular to each other and rotate. The small connection part 4 is formed of synthetic resin, and the large connection part 5 is formed by bend...
