Problems solved by technology

[0013] However, in the structure of the conventional key switch, in order to increase the stroke, the cup rubber 4 needs to be enlarged. If the cup rubber 4 is enlarged, the connecting rods 2 and 3 interfere with the cup rubber 4, so it is difficult to achieve a long stroke. Scheduling

Embodiment

[0027] (constitute)

[0028] figure 1 It is a structural diagram showing the key switch of the embodiment, figure 2 It is an exploded perspective view showing the push switch of the embodiment.

[0029] The key switch of the embodiment is composed of a key tip 1 , a first link member 2 , a second link member 3 , a cup rubber 4 , a case 5 , a contact piece 6 , a base plate 7 and a spring portion 8 .

[0030] On the key top end portion 1, there are provided rotation support portions 1a, 1b that rotatably support one end of the first link member 2, and figure 1 In the horizontal direction, the sliding support portions 1c, 1d at one end of the second link member 3 are slidably supported.

[0031] As shown in the figure, the spring part 8 is formed by, for example, stamping and bending an aluminum plate to provide fixing parts 8a, 8b and a spring 8c. In this way, the fixing portion 8a is disposed on the first connecting rod 2c described later of the first link member 2, and ...

Abstract

The invention provides a key switch which realizes long strokes, without enlarging a cup rubber 4 in a key switch, in which the pressing operation on a key top 1 is converted into rotational motion and sliding motion in horizontal direction using a first linking member 2 and a second linking member 3, and the first linking member 2 is housed in the second linking member 3 so that they do not overlap in the vertical direction. A spring part 8 is composed of fixed parts 8a and 8b and a spring 8c, in which the fixed part 8a fixes one end of the first linking member 2 to between rotating support parts 1a and 1b which support it so that it can rotate; and the fixed part 8b fixes one end of the second linking member 3 to between sliding support parts 1c and 1d which slidably support it, and puts between the key top 1 and the cup rubber 4 as a whole.

Description

technical field [0001] The present invention relates to a key switch used in a keyboard of a personal computer or the like. technical background [0002] (constitute) [0003] In recent years, with the popularization of notebook type personal computers, there has been a demand for thinner keyboards. Figure 8 This is a structural diagram of a conventional key switch adopted in response to the request for thinning. [0004] A conventional key switch is composed of a key tip 1 , a first link member 2 , a second link member 3 , a cup rubber 4 , a housing 5 , a contact piece 6 and a substrate 7 . On the key top end portion 1, a pair of rotation support portions 1r are provided to rotatably support one end of the first link member 2, and to support the second link member 3 so as to be slidable in the horizontal direction in the figure. A pair of sliding support parts 1s at one end. [0005] The first link member 2 has a pair of legs, and the first connecting rod inserted into ...
