Problems solved by technology

[0006] However, in such a contact structure 1 made of a plate-shaped metal, it is difficult to deform due to an increase in the strength of the metal plate, such as Figure 8 As shown, if insulating microscopic foreign matter 5 such as dust enters the inside of the switch and adheres between the contact structure 1 and the counter electrode 4, when the contact structure 1 and the counter electrode 4 are brought into contact, the metal plate will not It will be deformed according to the shape of the foreign object, and a gap 5a will be generated in a large range, resulting in a significant reduction in the contact area, and the problem of poor conduction of the button switch is likely to occur.

Embodiment 1

[0049] By etching a metal sheet made of SUS304 with a height of 50 μm, a metal body sheet 11 having a dense honeycomb-like structure is manufactured. The dense honeycomb-like structure is a hexagonal cross section. The through holes 6 are arranged. In this thin metal plate 11, the wall thickness (hereinafter referred to as line width) of the end portions 7a and 7b of the metal wall 7c is 20 μm, and the width between the metal walls 7c and 7c arranged in parallel (hereinafter referred to as the space width) is 185μm, the cross-sectional area of ​​the through hole 6 (hereinafter referred to as the void area) is 29640μm 2 The void area / the area of ​​the metal part of the metal body (hereinafter referred to as the opening degree) is 81.4%, and the filling rate (100-opening degree) is 18.6%.

[0050] On one side of such a metal sheet with a dense honeycomb structure, primer No. 18 (manufactured by Shin-Etsu Chemical Co., Ltd.) was applied with a brush, and then dried at 200 degrees Cel...

Embodiment 2 and comparative example 2

[0063] Except for using the same contact structure as in Example 1 and Comparative Example 1, and using an approximately spherical insulating foreign material 5 with an average particle size of 100 μm, the same conduction test as in Example 1 and Comparative Example 1 was performed . The results are shown in Table 2.

Embodiment 3

[0069] In use, it has a line width of 45μm, a space width of 380μm, and a hole area of ​​125054μm 2 , The metal body sheet 11 made of SUS304 with an approximately honeycomb dense structure with an opening of 79.9% and a height of 50μm, and the filling rate of silicone rubber is 20.1%, the same contact structure as in Example 1 was used. As for the body, the same conduction test as in Example 1 was performed except that a substantially spherical insulating foreign material 5 having a particle size of 200 μm was used. The results are shown in Table 3.

Abstract

In a push-button switch member provided with a movable contact composed of a metal member 7 constituting a contact surface to an opposing electrode 4, a number of holes 6 are formed to the contact surface in the height direction thereof, and the holes 6 are filled up with a filler 8 formed of a flexible resin.

Description

Technical field [0001] The present invention relates to a button switch component, which has a metal body in contact with a counter electrode, and particularly relates to a button switch component and a method of manufacturing the same, even if there is insulation between the button switch component and the counter electrode It is difficult to cause poor conductivity due to small foreign objects. Background technique [0002] Since the button switches used in power windows, door mirrors, etc. are all supplied with a high current of about 100 to 500 mA, a plate-shaped metal body is used as the button switch component . Moreover, in the conventional closed type (ノ-Mary-Cro-ズドタイプ) contact, in order to prevent the push button switch components from sticking to the counter electrode and cannot be separated, which is the so-called sticking phenomenon, a plate is used The metal body is used as a button switch component. [0003] in Figure 7 Shown in is a schematic cross-sectional view ...
