Problems solved by technology

[0014] However, the conventional keyboard switch 21 requires the bases 35, 36 which are parts for positioning the link members 33, 33, so the board 22 cannot be eliminated, and there is a problem that the number of parts increases.
[0015] In addition, when assembling, since the upper rotating shafts 33a, 33a of the link members 33, 33 have to be positioned on the seats 35, 36 formed on the base plate 22, there is a problem that many assembling man-hours are required.

Abstract

The present invention provides a keyboard switch which can reduce the number of assembly processes by decreasing the number of components and which can be easily assembled. First to third link members 5, 6 and 7 of a keyboard switch of the present invention include one end portions 5a, 6a and 7a and the other end portions 5g, 6g and 7g, which face each other. The first to third link members 5, 6 and 7 are installed so as not to cross each other, and have their one end portions 5a, 6a and 7a slidably supported by first to third slide supporting portions 3a, 3b and 4a formed on a key top, and their other end portions 5g, 6g and 7g rotatably supported by first to third rotating supporting portions 10a, 10b and 10c formed on a base plate 10.

Description

technical field [0001] The invention relates to a keyboard switch mechanism, in particular to a keyboard switch mechanism that uses a plurality of connecting rod parts to support key caps. Background technique [0002] if according to Figure 15 A conventional keyboard switch will be described. In the conventional keyboard switch, a substrate 22 is disposed on the lower side, and a keycap 23 is disposed above the substrate 22 . [0003] The substrate 22 is provided with a membrane switch 24 formed by laminating three film sheets on the lower surface, and the membrane switch 24 is sandwiched between the metal panel 25 and the substrate 22 . [0004] In addition, a through hole 26 is formed on the base plate 22, and around the circular hole 26, slide guides 27, 28 are formed standing upright from the base plate 22 and extending outward in parallel with the respective base plates 22. On the slide guides 27, 28, The lower rotation shafts 33b, 33b of the pair of link members 33,...
