(Step difference) 〇The through hole electrode surfaces 1 1 a, l 1 0 a / contact patterns 1 12 connected to the surface, and solder patterns 115 a and 115 b each connected to the back surface (see FIG. 1). Figure 2, Figure 3). An external connection terminal is constituted by a via electrode surface 110a (110a >) and a solder pattern 115a (115b). The through-hole electrode surfaces 110b and 110b are each connected to the front wiring pattern 1 1 3 a and 1 1 3 b and the back solder pattern 1 1 6 a and 116 b. The via electrode surface 110b (110b-) and the pattern for soldering (116a) (116b) constitute an external connection terminal. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs Secondly, the square sheet insulator 120 is made of heat-resistant resin such as polyimide, and its shape is approximately equal to that of the substrate 110. The central part is formed with a through hole 12 a (accommodating part) in accordance with the shape of the metal contact 130. As shown in FIG. 2, the insulator 120 is laminated on the surface of the substrate 110. At this time, the central portion of the fixed contact 1 1 1 and the contact pattern 1 12 is exposed from the through-hole 1 2 0 a. In addition, the paper size of the substrate applies the Chinese National Standard (CNS) A4 specification (210X297 mm) 512375 A7 B7 V. Description of the invention (7) (Please read the precautions on the back before filling this page) 1 1 0 insulator The contact portion of 120 is formed with an anti-etching 1 10 c in advance on the outer side of the through hole 12 a and on the inner side of the outer (edge) edge portion of the insulator 120 in advance (see FIG. 2). As a result, the escape (overflow) portions of the adhesive agent 1 6 0 a, 16 6 ◦ b are located between the substrate 1 1 0 and the insulator 1 2 0 inside and outside each anti-uranium agent 1 1 0c, so that the adhesive is adhered. When the insulator 1 2 0, even if the adhesive 1 70 is crimped on the bonding surface, almost no pressure is applied to the escape portion. Therefore, the adhesive 1 7 0 does not produce a metal contact 1 3 0 side. And the outer (edge) edge portion of the insulator 1 2 0 is exposed (protruded) to the outside. It is also possible to form the insulating layer by screen printing instead of the anti-uranium agent. Next, the rectangular sheet-like cover plate 140 is formed of a heat-resistant resin such as polyimide, and its outer shape is substantially the same as that of the insulator 120. The cover plate 1 40 is laminated to cover (cover) the surfaces of the metal contacts 130 and the insulator 120 to prevent the metal contacts 130 from detaching from the substrate 1 100 and to prevent the flux or the like from penetrating into them. Substrate 1 10 surface. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs, the cover plate 140 is adhered to cover the insulator 1 2 0 containing metal contacts 130, so it is more like a dome-shaped movable. When the top of the contact is directly adhered to the outer periphery, it can be easily adhered without the cover 140 having a roll or the like. Furthermore, because the metal contacts 1 30 are accommodated in the through-holes 1 2 0 a of the insulator 1 2 0 covered by the cover plate 1 40, the metal contacts are pressed for the switching operation (to be described later). At 130, the place where the pressed part escapes can be formed, so the pressing force of the metal contact 130 will not increase to the design level, and a good operation feeling can be obtained. -10- This paper size is in accordance with Chinese National Standard (CNS) A4 specification (210X297 mm) 512375 A7 B7 V. Description of the invention (8) It is on the back of the substrate 1 1 0, and the adhesive to be used to adhere to the insulator i 2 0 The same adhesive is used to adhere the spacer 1 50 (the dream picture 2) made of the same material as the insulator 1 2 0 to cover the wiring pattern 1 1 4 (refer to FIG. 4) to prevent from the through-hole electrode 1 1 1 a, 1 1 丄 b Infiltration of flux or dust. When the fixed insulator 1 2 0 and the cover plate 1 40 are to be adhered to the substrate 1 10, a pressure is applied in a heated state in order to harden the adhesive layer, but in this case, in a normal state, the substrate The coefficient of linear expansion of each raw material of 1 1 〇 and the aforementioned insulator 1 2 0 is different (glass epoxy resin is 2 50 ~ 3 0 0 p pm / ° C, polyimide resin is 2 5 ~ 2 8 ppm / ° C), it will be hardened. After cooling, the substrate 1 1 will bend, so that the contact of the switch contact part will become unstable, or the pattern 115a, 115b, 116a, 1 1 6 b to A circuit board of an electronic device or the like floats and a connection failure occurs. For this reason, in this embodiment, the aforementioned spacers 150 made of the same material as the aforementioned insulator 120 are also formed on the back surface of the substrate 110, so that the substrate 110 can be prevented from being bent. The spacer 150 is formed corresponding to the insulator 1 2 0 so that the occupation ratios on the substrate 1 10 are slightly the same as each other, and the spacer 150 is formed on the substrate except that The pattern for soldering at the 1 10 end portion 1 1 5 a, 1 1 5 b, 1 1 6 a, 1 1 6 b is formed thicker than the thickness of the pattern for soldering.

At this time, the solder is connected so as to be wound around the through-hole electrode surface 1 10a, 110a >, 110b, 110b > of the substrate 110, so that the circuit substrate can be strongly fixedly connected. At this time, The spacer 1 50 (refer to FIG. 2) arranged below the substrate 1 1 0 and A gap is formed between each of the solder patterns 1 1a, 115a, 116ab, 116b and the aforementioned grounding portion, so that the flux (solder) will flow into the portion and prevent the bearing surface of the push button switch 100 from floating. In addition, as shown in FIG. 2, although the insulators 120 and the cover plate 140 have a distance L protruding from the upper side of the through-hole electrode surfaces 110a, 110a /, 110b, and 110b /, the distance Because L is extremely small, this part does not hinder the soldering flux to be viewed from the surface of each through-hole electrode. As shown in FIG. 1, since the through-hole electrode surfaces 110a, 110 a '110b, and 110b are provided on the substrate The four corners of 110 can make the contact pattern 112 uniformly and equally wider than the fixed contact 1 1 1 at the center, so that the space on the substrate can be used in the design of the pattern very efficiently.

V. Description of the invention (16) The above-mentioned side surface of the substrate is formed by laminating in a flat shape parallel to the side surface, so that, for example, a plurality of movable contacts are arranged in the arrangement A plurality of fixed contacts are arranged on a large sheet of substrates. After covering the cover of the large sheet and a plurality of movable contacts, the cover is divided into individual button switches. , The cut surface may be disposed along and close to the metal layer thus configured is configured (overflow) to the holes of the cover plate does not require pre-arranged metal layer corresponding to the escape. As a result, the number of man-hours for machining the escape hole can be reduced, and since it is not necessary to form a cover plate with the escape hole to precisely position the substrate on a large substrate, the effect of shortening the manufacturing process can be exerted. The length of the cover plate protruding from the metal layer can be made small, so that when the push button switch is mounted on a circuit board or the like and soldered, the solder (soldering) portion can be easily viewed. In addition, the metal layer is a through-hole electrode surface, so that the metal can be formed in a large sheet state, and the process can be simplified. In addition, an insulator having a receiving portion to receive the movable contact is laminated between the substrate and the cover, so that it is not rolled when the cover is directly adhered to the surface of the dome-shaped movable contact as is conventionally known. Wait for easy sticking. Furthermore, since the movable contact is housed in a housing portion of an insulator covered with a cover plate, it is possible to form a place for the escape of the air of the pressed portion when the movable contact is pressed to generate an action. The pressing pressure does not increase to the design level or more, and a good operation feeling can be obtained. Also, when assembling a push-button switch, the insulator can be configured so that it does not need to be provided with an escape hole corresponding to the metal layer in advance, so that the manufacturing process of the push-button switch can be further shortened. Furthermore, the substrate has a square shape, and the metal layers are formed at the four corners of the substrate (please read the precautions on the back before filling this page). «1 Order
