Description of the invention: [Technical field to which the invention belongs] The present invention relates to the structure of a push-button switch used as an operation switch of various electronic devices, and more particularly to a dome-shaped bulging portion that is turned by pressing to make contacts. The structure of the movable contact body of the contact or separate push button switch. [Prior Art] The structure of the Shirai push button switch has a structure of a sheet switch in which a plurality of circular dome-shaped movable contact bodies are arranged on a substrate (for example, refer to Patent Document 1). The construction of such a conventional thin-plate switch is shown in FIG. 7. Fig. 7 is an exploded perspective view showing a thin-plate switch. In the figure, the first thin plate 51 is a thin film-shaped insulating thin plate, and an adhesive material is applied to the lower surface. The movable contact 53 is formed in a dome shape from an elastic metal material, and has a bulging portion which can be turned in the center. The second thin plate 54 is provided with a storage hole 54a in which the movable contact 53 is stored. The movable contact 53 is stored in the storage hole 54 & and the i-th thin plate 51 is adhered to the upper surface thereof. The circuit board 58 is formed with a plurality of circuit patterns of an outer fixed contact 59 and a central fixed contact 60 made of a conductive material. The second thin plate 54 is adhered to the circuit board 58 such that the lower end of the outer periphery of the movable contact 53 is brought into contact with the outer fixed contact 59, and the top of the bulged portion is opposed to the central fixed contact 60. In addition, the movable contact 53 is pressed through the first thin plate 51 to turn the bulging portion, whereby the movable contact 53 is brought into contact with the central fixed contact 60, thereby making electrical connection. {疋 Recently, due to the miniaturization of the movable contacts and the narrow pitch of the arrangement of the movable contacts 94692.doc 1238425, θ requires the miniaturization of the entire thin-plate switch. The movable contact itself has also been miniaturized and reduced to a small diameter. Therefore, the height of the bulging portion becomes small, and a problem arises that a desired operation stroke cannot be obtained. Therefore, a switch having a structure in which leg-shaped pieces are protruded from the outer periphery of a circular dome-shaped movable contact to extend the stroke has been proposed in order to extend the operation stroke (for example, refer to Patent Document 2). FIG. 8 shows the structure of a contact spring of a conventional switch. In the figure, the occupying bullet η 111 is formed as a shallow circle D which is a spherical portion as a whole, and a foot u2 is formed in a state of being extended at four places on its outer periphery. This contact dance spring 111 ′ performs a combination of a turning action and a bending action of the foot 112 when the top of 11 is pressed, so that the operation stroke generated by pressing can be increased. Patent Document 1 · Japanese Patent Application Laid-Open No. 2001-14973 Patent Document 2: Japanese Patent Application Laid-Open No. 2000-348556 However, in the structure of the above-mentioned push button and movable contact, it is necessary to use the movable contact The miniaturization and the narrow pitch of the movable contact arrangement realize the miniaturization of the entire thin-plate switch, and the use of an α-shaped movable contact with a smaller diameter size will increase the height of the bulging portion accordingly. A problem arises that a desired operation stroke cannot be obtained. . Therefore, although it is considered that a foot is protruded from the periphery of the movable contact to prolong the operation stroke ^, the problem of a long-term application of cracks at the root of the foot due to the "operation capacity" arises. [Summary of the Invention] Therefore, an object of the present invention is to solve the above-mentioned problems, and to provide a movable contact body that improves reliability, secures a desired operation stroke, and achieves miniaturization, and a push button switch using the same. In order to solve the above-mentioned problem, the ith solution of the present invention is configured to include a lower end peripheral portion placed on the fixed contact, a skirt portion standing at a predetermined angle from the lower end peripheral portion, and The skirt is connected to the dome-shaped bulging portion which can be turned over, and the aforementioned cymbals are cut in parallel on opposite sides of the square. It is formed in an elongated shape with openings on both sides of the face, the skirt is formed at a position facing each other with the bulging portion interposed therebetween, and the center of the circle constituting the outer periphery of the lower end peripheral portion and the The tops of the dome-shaped bulges connected to the skirts are different from each other. In addition, the second solution is configured such that a lower end peripheral portion of the skirt portion is formed by a larger arc than an arc formed by a center of a dome-shaped bulged portion connected to the skirt portion, and the lower end is formed. Both ends of the arc of the peripheral portion are placed on the fixed contact. In addition, the third solution is configured to connect a plurality of movable contact bodies as described in the first or second solution to a strip-shaped metal plate through a punched residual edge, and form the punched residual edge. On the outer peripheral portion except for the opening portion of the skirt portion and both end portions of the lower end peripheral portion.

In addition, since there are no unnecessary protrusions in the outer shape of the movable splicing body 3, the reliability can be improved. FIG. 4 shows that a plurality of the movable contact bodies are formed into a band-shaped metal by punching the residual edge. An endless belt-shaped movable contact body 3 in a state on the plate 4. In this case, the movable contact body 3 has a pair of openings formed on the opposite side surfaces of the opposite side of the side part ^ in parallel, and the lower end peripheral part 3a formed on the skirt part. The above-mentioned blanking residual edge 4a is formed on the outer peripheral part of the foot part ㈣ on both ends. In addition, in the figure t, the hatched portion indicates a void (punching). As described above, by forming the movable contact body 3 in the shape of an endless belt, the turning force Γ of the movable contact 3 can be easily and stably supplied. In addition, the blanking edge h is formed at the position of the opening portion 3d having a large amplitude during the operation and the contact portion 3e fixedly connected to the periphery of the black sub-connection. Therefore, the name is 94692.doc • 12-1238425 When the movable contact body 3 is cut from the endless belt material, even if the cutting residue of the punching residual edge 4a is generated, the occurrence of cracks can be suppressed, and the fixed contact 2b with the periphery can be prevented from being cut off. The contact surface makes the contact unstable. 5 and 6 show a movable contact body 3 of a thin plate in which a plurality of movable contact bodies 3 are adhered to the openings 3d of the adjacent movable contact bodies 3 with respect to each other. In this case, the peeling plate 7 is adhered to the adhesive surface side (lower side) where the adhesive 6 is applied to the adhesive plate 5. The peeling plate 7 is used to protect the movable contact body 3 during transportation and assembly until the movable contact body 3 is placed on the fixed contact 2 of the insulating substrate. As described above, by adjoining the adjacent openings 3d to each other and forming a horizontal strip shape, the movable contact body 3 is adhered to the adhesive plate 5 to achieve a narrow pitch of the thin-plate switch. In addition, by covering the lower surface of the adhesive plate 5 with a protective peeling plate 7, the handling, preparation, and assembly can be easily performed, and the operability can be improved. Moreover, in the above-mentioned embodiment, although a thin-plate switch is constituted by one thin plate of the adhesive plate 5, a pad plate provided with a receiving hole for receiving the movable contact body 3 may be provided between the adhesive plate 5 and the peeling plate 7. . Alternatively, a strip-shaped adhesive tape narrower than the movable contact body 3 may be used instead of the adhesive plate 5 to adhere the upper surface of the movable contact body 3 to each of the contacts.
