The fixed contact 7 includes a central fixed contact 7b provided at the center, and a central fixed contact 7a provided between the central fixed contact 7a and opposite peripheral fixed contacts 7b provided on both sides. The 'peripheral fixed contacts 7b may be oppositely arranged, or may be arranged in a comb-tooth shape or a ring shape. In addition, the peripheral fixed contacts 7b may also be arranged. Instead of arranging a pair of opposite contacts, only one place is arranged. · When the sheet with the movable contact is mounted on the insulating substrate 6, the separation sheet 5 is peeled off from the side 2 (lower side) of the bonding part 2 of the i-th sheet i, and borrows 97322.doc -16- 200523962 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 abuts on the peripheral fixed contact, and at the same time, a contact portion 3f 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. Hereinafter, the operation of the button switch configured as described above will be described. In the initial state shown in Figs. 5 and 6, the two fixed contacts 7a and 7b are not conductive, and the switch is 0FF. Here, "the upper side of the second sheet 4 is pressed by an operating unit such as an electronic device (not shown), and the projecting portion 3c on the dome of the movable contact 3 is pressed downward to flip it over." The contact portion 3f on the lower side of the protrusion 3C is in contact with the central fixed contact disposed opposite to each other, and the movable contact 3, the central fixed contact 7a, and the peripheral fixed contact 7b are electrically connected to each other and become an ON state. output signal. In addition, the operation section of the above-mentioned electronic device is provided with a pressing section for pressing while pressing the dome-shaped section surrounded by the contact section 3f. The operating portion is preferably provided with a pressing protrusion on the rubber sheet. At this time, even if there is a _twist deviation, the pressing protrusion of the rubber sheet can be deformed and the arch portion can be bent. Therefore, the contact portion 3f can be reliably abutted in the center, and can be trapped in the receiving hole la. As the movable ^ 3 moves out from the above connection to the adjacent adjacent receiving hole h in. Therefore, there is no need to worry that it will hinder a good turning action of the movable contact. _ Action of Rishou 'can be obtained. In this case, foreign matter is intruded into the contact in the adjacent receiving hole 1a. The workbook U is 71. Therefore, it is possible to prevent it from standing out from the first and second sheets. In addition, as a way to obtain a good turning action; 97322.doc 200523962 can also replace the connection slot lb and the second sheet 4 and the insulating substrate. 6 is provided with an air hole communicating with the receiving hole la. In addition, a space is provided between the inner wall of the receiving hole 1 a and the outer periphery of the movable contact 3 on this day, and the gap is formed so that the inner wall of the ridge portion of the receiving hole 1 and the outer periphery of the movable contact 3. The gap S2 is wider than the wide towel field of the receiving hole h. The gap $ 1 between the inner wall of the cymbal and the outer periphery of the movable contact 3 is large. In this way, the space between the inner wall of the narrow portion of the receiving hole la and the outer periphery of the movable contact 3 is large, so that the adhesive portion 4a between the second sheet 4 and the i-th sheet can be separated from the narrow of the movable contact 3. Since the outer periphery in the width direction reduces the restraint of the movable contact 3 caused by the second sheet * sticking, it is possible to perform a more reliable turning operation. Next, when the pressing of the second sheet 4 is released from the above state, the movable contact 3 is flipped upward due to its own elastic force, and the flip protrudes due to the flip: the contact portion on the lower side of 3c is fixedly connected from the center. The points are separated from each other, and the central fixed contact point ~ and the peripheral fixed contact point 7b are electrically cut off and become OFF. ^ ^ Due to the / 0 receiving order, the long direction of the movable contact 3 in the receiving hole la & sets the connecting direction connecting the connecting groove ^ between the receiving holes la, so when the movable contact 3 is flipped, The adhesive portion 4 of the second sheet 1 near the narrow portion of the movable contact 3 is cut on the insulating substrate 6 so that it can be reliably weighed and prevent the adhesive from entering the contact. ^ This' will mount the sheet with the movable contact 3 that houses the movable contact 3 described above. ^ The insulating substrate 6 is provided with a top-shaped outer portion that contacts the lower end peripheral portion of the movable contact 3. ^ P 6 peripheral fixed contact 71 >, And the central fixed contact ㈣ opposite to the round outer dog portion 3C of the movable contact 3, so that the structure of a thin-type push button switch can be easily obtained by 97322.doc -18- 200523962, and it can provide an improvement due to the above configuration. n A button switch that is guilty, ensures the desired stroke, and can be miniaturized.
