A sheet-type button switch structure (see, for example, Patent Document 1). The structure of such a conventional sheet with a movable contact and a known switch is shown in FIGS. 7 and 8. Fig. 7 is an exploded perspective view of a conventional sheet with a movable contact, and Fig. 8 is a cross-sectional view of a main part of a button switch using a conventional sheet with a movable contact. In the figure, a plurality of movable contacts are made of a flexible round dome-shaped sheet metal such as stainless steel or phosphor bronze, and can be displaced in accordance with the forcing force from the top. In addition, the movable contact 51 does not have a hole penetrating into the dome shape, but has a contact portion 5ia formed in a central portion thereof so as to protrude into the dome shape. The adhesive sheet 52 is formed of a thin base material such as a polyester resin. The adhesive sheet 52 includes a flexible sheet-like sheet portion 53, a plurality of holes 52 a provided in the sheet portion 53, and a, and is disposed in an air passage except a non-adhesive portion. The adhesive tape 54 of a portion other than the portion 55 is formed, and the airway portion 55 is formed under the sheet portion 53 except for the hole 52a. 97322.doc 1242224 The airway portion 55 is formed by screen printing the adhesive 54 under the sheet portion 53. At least one end of the airway portion 55 is connected to the hole 52a of the adhesive sheet 52 or the airway opening 56 at the outer peripheral edge 52b of the adhesive sheet 52. Connected. In addition, the upper surface of the movable contact 51 is adhered by the adhesive 54 of the adhesive sheet 52, and the upper surface of the movable contact 51 and at least a part of the movable contact end portion 5 lb are attached to the airway portion 55 and adhered. The sheet 57 is formed of a polyester resin film having substantially the same shape as the adhesive sheet 52, and has a plurality of holes 57a formed therethrough. In addition, the separator 57 is adhered to the lower surface of the adhesive sheet 52 by the adhesive 54 of the adhesive sheet 52, and the holes 52a of the adhesive sheet 52 and the holes 57a are opposed and overlapped. The movable contact 51 is sandwiched between the spacer 57 and the adhesive sheet 52, and the lower surface of the movable contact 51 is protected, thereby forming a sheet 58 with the movable contact.

The sheet 52 effectively reflects light to illuminate the operating body that presses the movable contact 51. (Not shown). FIG. 8 shows a push button switch. The insulating substrate 59 is formed of a flexible substrate such as a polyimide film. On the surface, a first fixed contact 59a made of copper foil and formed around the first fixed contact 59a are formed by etching. The second fixed contact 59b having a substantially U-shape at the point 59a. Then, the spacer 57 adhered to the lower side of the adhesive sheet 52 with the movable contact-attached sheet 58 is peeled off, so that the adhesive sheet_adhesive 54 is exposed, and the end portion 51b of the movable contact 51 and the second fixed contact are peeled off. In contrast to 59b, the adhesive sheet 52 is stuck on the insulating substrate 59. At this time, the 'movable contact 51' is mounted on the surface of the insulating substrate 97322.doc 1242224 board 59 in a state where the periphery of the end Sib is always in contact with the second fixed contact. Patent Document 1 · Japanese Patent Application Laid-Open No. 2001-160334 However, in the above-mentioned conventional sheet and push button switch structure with a movable contact, there are problems in that the size of the movable contact and the arrangement pitch occupied by the movable contact are problematic. The size of the thin-type pushbutton switch brought about by the narrowing, and the use of a circular dome-shaped movable contact with a smaller twist size results in a reduction in the height of the protruding portion. Therefore, it is used for turning over the protruding portion. The amount of movement is small, and a desired operation feeling cannot be obtained. SUMMARY OF THE INVENTION Accordingly, the present invention has been made in order to solve the above-mentioned problems, and an object thereof is to provide a sheet with a movable contact capable of ensuring a desired operation stroke, miniaturization, and good operation feeling, and a sheet using the sheet. power switch button. In order to solve the above-mentioned problem, the thin film with a movable contact according to the first solution of the present invention employs a structure system having two opposite sides having a dome-shaped protrusion and a lower peripheral portion of the sacral protrusion. The side portion is cut to form a long movable contact; a first sheet having a receiving hole capable of accommodating the movable contact; and a portion having a bonding portion on the back surface and holding the movable contact by the bonding portion and blocking the first contact. The second sheet on the receiving hole of 1 sheet; the receiving hole of the first sheet is formed in a long shape including a wide portion and a narrow portion, so that the movable contact forms a narrow side surface and the receiving hole. The narrow portion corresponding to and accommodates the movable contact in the receiving hole. In addition, the configuration used in the second solution is to provide a predetermined gap between the inner wall of the receiving hole and the outer periphery of the movable contact, and the configuration of the gap is such that the inner wall of the narrow portion of the receiving hole is opposed to the inner wall of the receiving hole. The gap between the outer periphery of the movable 97322.doc 1242224 contact is larger than the gap between the inner wall of the wide portion of the receiving hole and the outer periphery of the opposite movable contact. In addition, the configuration used in the third solution is: forming a plurality of the receiving holes in the first sheet, and accommodating a plurality of the movable contacts in the receiving holes, and narrowing the narrow portions of the adjacent receiving holes. A plurality of arrays are arranged opposite to the narrow width portions of the adjacent movable contacts. In addition, in the structure of the '4th solution, an adhesive portion is provided on the back surface of the first sheet, and the adhesive portion is covered with a peelable release sheet. In addition, the constitution used in the fifth solution is that the first sheet is formed with a connection groove for an air flow path between inner walls of the adjacent receiving holes, and the second sheet covers the receiving hole and the A protective sheet covering the receiving hole and the lower surface of the coupling groove is provided on the upper surface of the coupling groove. -In addition, the configuration adopted in the sixth solution is: the configuration adopted in the seventh solution, except that the connection groove is provided along the longitudinal direction of the movable contact accommodated in the trough hole, and the configuration adopted in the seventh solution: the above The movable contact has a skirt portion which rises at a predetermined angle from the peripheral portion of the lower end and is continuous with the rest: a dome-shaped outer protrusion which is inverted. The peripheral portion of the lower end of the skirt portion is protruded by a circle which is continuous with the skirt portion. The arc formed by the middle collar of the part is larger and the arc is formed, and the fixed contact of the arc of the lower peripheral part of the substrate is fixed.丨 The composition system used in the 8th solution of Juebu: has any of the 丨 $ schemes: η tear, +, ,, 1 ~ 7 solutions, and a thin sheet with movable contacts , The second contact of the lower end peripheral portion of the movable contact in the sheet containing the 97322.doc 1242224 == the movable contact, and the ridge-shaped outer protrusion which is arranged adjacent to the peripheral fixed contact and is in contact with the movable = The top and bottom of the can be contacted with the fixed fixed contact and the insulating substrate provided with the peripheral fixed contact and the upper contact. The effect of the T. dog mouth invention is as described above, the movable contact of the present invention, and the protrusion and the protrusion are adjacent to the _, ^, ',-. The two sides of the two sides of the two sides are cut by the openings of the first U-shaped adhesive contact portion of the movable contact, and the second portion of the above-mentioned receiving hole of the first sheet can be held by the adhesive portion; A long strip composed of a wide section and a narrow section ... The narrow contact portions forming the narrow sides of the two sides and the receiving hole are used to receive the movable contact in the receiving hole. Therefore, it corresponds to the first === section. It accommodates long movable contacts with dome-shaped protrusions on the ground, and from now on, the operation scale when flipping the zygomatic protrusions is large, and at the same time, it can be miniaturized to obtain a good feeling. The predetermined gap is formed between the inner wall of the hole and the outer periphery of the movable contact. The formation of the gap allows the inner wall of the narrow portion of the receiving hole to be opposite: the gap between the outer periphery of the movable contact is wider than the receiving hole. ㈣ = Moving: The gap between the outer periphery of the point is large. Therefore, the narrow space of the receiving hole, the inner soil, and the gap between the outer periphery of the movable contact are large. Therefore, the second sheet: the bonding portion with the first! Sheet can be kept away from the movable part. The contact ’s narrow width perimeter reduces the restraint of the movable contact caused by the adhesion of the second sheet to 97732.doc 1242224, which allows more reliable flipping operations. In addition, multiple accommodations are formed on the 14th piece Holes, ^ movable contacts are accommodated in these receiving holes, and the narrow portions of the adjacent receiving holes and the narrow portions of the adjacent movable contacts are arranged in multiple groups facing each other. The movable contacts are integrated with the i-th sheet, and the key spacing is narrow.

By providing the protective sheet, the upper and lower sides of the through hole constituted by the receiving hole 13 and the sink groove lb and the like can be covered with a sheet, and dust can be prevented from entering from the outside. When the contact reading sheet is assembled on the insulating substrate 6, it is peeled from the first sheet i. In addition, the second sheet 4 is formed of one sheet having a substantially rectangular shape 2 similar to the first sheet 1. However, a plurality of small pieces may be replaced into four separate spoons (/ not shown) Separately formed and kept separate by this separate sheet 97322.doc -15-1242224 Don't store on the top of the movable contact 3 in the storage hole 1 a of the first sheet 1, and plug the top of the storage hole 1 a The states are adhered to the upper surface of the first sheet 1. In the sheet with the movable contact configured as described above, the receiving hole la of the first sheet 1 is formed into a long shape composed of a wide portion and a narrow portion, so that the movable contact 3 forms the narrow side faces of both sides. The movable contact 3 is stored in the receiving hole 1 & corresponding to the narrow portion of the receiving hole la, and has a dome corresponding to the narrow portion of the trough hole 1a of the first sheet 1 The elongated movable contact 3 is formed in the shape of the projecting portion 3c. Therefore, the operation stroke when the dome-shaped projecting portion 3c is reversed can be set to be large, and at the same time, it can be miniaturized and a good feeling can be obtained. That is, as compared with the case where the movable contact 3 is formed into a dome-shaped movable contact having the same diameter as that of the narrow side surface portions, the height of the outer protrusion can be increased, and as a result, a large operation stroke can be secured. Figures 5 and 6 show the structure of a push button switch using a sheet with a movable contact. The base plate is formed of an insulating substrate 6 and a layer of 4 layers such as grease. On the insulating substrate 6 is formed by Fixed contacts 7 printed with a conductive material such as carbon or rhenium. The fixed contact 7 is composed of a central fixed contact 7a provided in the center and peripheral fixed contacts 7b provided on both sides of the central fixed contact to be opposed to each other. Also, the 'peripheral fixed contacts 7b may be arranged relative to each other-pair, or may be arranged in a comb-tooth shape or a ring shape. In addition, the outer peripheral fixed contacts 7b may not be arranged in a pair, but only in one place. The insulating substrate 6 is mounted on the right side. Ten, taxis, and the sheet with the movable contact are attached. The peeling sheet 5 is peeled from the side 2 (the lower side) of the bonding part 2 of the first 1y j aa 4 sheet. 97322.doc 1242224 The first sheet 1 is adhered to the insulating substrate 6 by the adhesive portion 2 of the first sheet 1. At this time, the abutting portion 3e of the movable contact 3 is in abutment with the peripheral fixed contact 7b. At the same time, the contact portion 3f composed of a plurality of protruding portions on the back of the dome-shaped outer protruding portion 3c is fixedly connected to the center. The points 7a are separated from each other. The operation of the above-mentioned push button switch is described below. In the initial state shown in Figs. 5 and 6, the two fixed contacts 7a and 7b are not turned on, and the switch is in the OFF state. Here, when the upper side of the second sheet 4 is pressed by an operating unit such as an electronic device (not shown), the outer protrusion 仏 on the dome of the movable contact 3 is pushed downward and turned over. The contact portion 3f on the lower side of the protrusion 3c is in contact with the central fixed contact 7a arranged opposite to each other. The movable contact 3, the central fixed contact 7a, and the peripheral fixed contacts are electrically connected to each other, and are output in a ⑽ state. signal. In addition, the electronic voice-activated operation 咅 P is provided with a pressing member that presses while bending the dome-shaped portion surrounded by the contact portion 3f. The operating portion is preferably provided with a pressing protrusion on the rubber sheet. At this time, even if there is some deviation, the pressing protrusion of the rubber sheet can be deformed and the arch portion can be bent. Thereby, the contact point_ can be reliably abutted on the central fixed contact point 7a. : When the air trapped in the receiving hole U is turned at the time of the dagger, as the movable contact 3 is turned over: It flows out to the other adjacent storages connected through the connection ㈣. Therefore, there is no need to worry that it will interfere with the operation when the movable contact 3 is inverted, and a good inversion operation can be obtained. In this case, since the air moving due to the inversion flows into the phase =: hole U, it is possible to prevent foreign matter from coming into contact between the i-th and the second sheet. In addition, as a good way to obtain a good reversing action, 97322.doc -17-1242224 may replace the connecting groove lb and provide an air hole in the second sheet 4 and the insulating substrate 6 that communicates with the receiving hole la. In addition, at this time, a gap is provided between the inner wall of the receiving hole 丨 a and the outer periphery of the movable contact 3, and the gap is formed so that the inner wall of the narrow portion of the receiving hole la and the outer periphery of the movable contact 3 The gap S2 is larger than the gap si between the inner wall of the wide portion of the receiving hole and the outer periphery of the movable contact 3. In this way, the gap S2 between the inner wall of the narrow portion of the receiving hole la and the outer periphery of the movable contact 3. It is large, so that the bonding portion between the second sheet 4 and the i-th sheet 1 can be moved away from the outer periphery of the movable contact 3 in the narrow width direction. Therefore, the movable contact caused by the second sheet 4 being bonded to a The restraint of 3 is relieved, and a more reliable turning operation can be performed. Next, if the pressing of the second sheet 4 is released from the above state, the movable joint 3 is turned upward due to its own elastic force, and the overhang is caused by the turning. The contact portion on the lower side of 3c is separated from above the central fixed contact, and the central fixed contact 7a and the peripheral fixed contacts are electrically cut off and become 0ff. Long direction of movable contact 3 _ set link above The connection direction of the above-mentioned connection groove ^ between the receiving holes 1a. Therefore, when the movable contact 3 is reversed, the adhesive portion 4a of the second sheet 4 near the narrow portion of the movable contact 3 does not adhere to the insulating substrate 6. Obtain a reliable reset, and at the same time prevent the adhesive portion 4a from entering the inside of the contact. In this way, the thin sheet with the movable contact of the above-mentioned movable contact 3 is loaded, and the insulating substrate 6 is disposed with the movable Lower end peripheral portion of contact 3 · Peripheral fixed contact% contacted by abutment portion 3e of 3a, and central fixed contact 相对 opposite to movable contact head and apex-shaped projecting portion 3c, which can easily 97322 .doc -18 · 1242224 The structure of a thin-type button switch is obtained.
