In addition, the operating member 6 is placed on the device The pressing portion 6d protruding from the cutout window portion 丨 c of the casing 丨 is pressed on the dustproof sheet 5 on the upper surface of the casing 丨 and is disposed in the storage portion "of the casing 1 so as to be movable in the lateral direction. 盍The body 7 is formed by punching and bending a conductive metal plate, and has a flat upper plate portion 7a of 95961.doc -12 · 1238426, and is provided at four corners of the upper plate portion 7a and is connected to the housing j. The protrusions lb on the upper side are locked by the locking recess 7b, which protrudes from the opposite side 上 of the upper plate portion ~, and is bent along the side of the housing 1 in a state where a gap s is formed and extends downward. And a plurality of locking arm portions 7d protruding downward from the other side end and respectively locked with locking portions (not shown) of the housing 1. The upper plate portion 7a of the carcass 7 is formed. A slanted piece 7e is provided, which is cut from the central portion to the inside of the storage portion 1a of the housing 1, and the head end side thereof is inserted and provided in The opening portion on the base portion 讣 of the operation member 6 is centered and faces the central portion 4b of the movable contact point *. The inclined sheet region is formed by bending downward, and is provided on the operation member 6 The working portion 6c of the head end of the flexible arm portion ^ slides on the slope of the inclined piece 7e, and the center of the moving portion is pressed, so that the central portion of the movable contact 4 is pushed downward and pressed. The pair of leg portions 7e formed by the opposite pair of side ends of the upper plate portion 73 of the cover body 7 projecting and extending downward is formed in a manner facing the operation direction 6 of the operation member 6 and facing each other with the inclined pieces interposed therebetween. Two side portions are formed to extend to both sides of the housing. When assembling the push-button switch having the above configuration, first, a movable contact 4 is placed in the housing ⑽ storage portion U, and the movable contact 4 is used for The dust-proof sheet 5 is covered, and the periphery of the dust-proof sheet 5 is attached to the upper surface of the casing 1. Then, after the operation member 6 is arranged on the dust-proof sheet 5, the cover 7 is placed on the casing 1. At this time, 'by inserting the protrusions 1b into the locking recesses formed on the four corners, respectively In the eighth part, the locking wrist portion 7d is locked with the locking portion (not shown) of the casing 1 respectively. 95961.doc -13- I238426 The operation of the push-button switch having the above configuration will be described below using FIGS. 3 and 4. First of all, in the initial state when #Working member 6 is not pressed, as shown in FIG. 3, "The center of the operating part of the working member 6 is located near the bending part 2 of the inclined piece 7e of the cover 7, and near the root σ 卩. Without elastic displacement downward, the movable contact 4 and the fixed contact 3 will be separated. From this state, when the pressing portion of the operation member 6 is "pressed in the right direction shown in Fig. 4, the operation member 6 The moving part 6c is guided by sliding on a slanted slanted surface cut in from the cover body 7 to the inside of the housing 1. Accordingly, the moving part 6c is elastically displaced by the arm part 6e as shown in FIG. In the downward direction (clockwise), the head end of the moving part presses the central part of the movable contact 4 through the dustproof sheet 5. In this way, the central portion 4b is turned downward to contact the fixed contact 3 and the switch is turned on. When the press-shaped energy of the pressing portion 6d is released from this state, since the elastic force of the arm portion 6e is used, the center of the operating portion is rotated on the inclined surface of the inclined piece 7e while rotating in the upward (counterclockwise) direction of FIG. 4. Therefore, the operation member 6 slides in the left direction in FIG. 4 and returns to the initial state. At this time, 'as the action part ㈣ rotates, the central part of the movable contact 4 is also turned upward by the elastic force to leave the fixed contact 3, and the switch is turned off. The state shown in Figs. 6 and 7 shows a state in which the on-demand switch surface configured as described above is mounted on a mounting substrate such as an electronic device (not shown). On this day, the external connection terminals 2a and 3a for surface mounting formed by protruding the side surface of the peripheral device 1 are mounted on the mounting substrate 8 by soldering with solder 9. In addition, at the same time, it protrudes from the opposite pair of side ends of the upper plate portion 7a of the cover body 7 and is bent downward to form a gap s along the side of the casing 1 facing 95961.doc -14-1238426. Similarly, the leg portion 7c is soldered to the head end side with solder 9. During the operation of the button switch constituted by the fan, the upper plate portion 7a of the cover 7 uses the action portion 6c of the operating member 6 to slide on the slope of the inclined piece 7e. Blow up with force. However, in this configuration, since the cover body 7 is formed of a metal plate, and the two side portions facing each other toward the housing 1 are formed by sloping a part of the cover body 7 from a gap with respect to the operating direction of the operation member 6 toward the housing 1. The two side surfaces are extended to form a leg portion 7c. The head end of the leg portion 7c and the external connection terminal 2a are simultaneously soldered to the surface-mounting substrate 8. Therefore, by mounting ¥ to the substrate 8, By soldering the leg portions 7c (deformation preventing portions) of the cover body 7 simultaneously with the external connection terminals 2a and 3a, the cover body can be reliably prevented from floating. In addition, in FIG. 7, the external connection terminals 2 a, 3 & with respect to the operation direction of the operation member 6 are arranged on the rear end side than the center of the housing 丨, and the width W1 of the leg portion 7 c is made larger than the external connection terminal. The width W2 of 2a and 3a is more sought. By forming the leg portion 7c in this manner, a large soldering area of the leg portion 7c can be ensured, so that the soldering by the solder 9 can be performed firmly. In addition, since the pressing portions 6 (1 and external connection terminals, 3a ') of the operation member 6 are disposed at positions facing each other between the leg portions 7c (deformation preventing portions), the pressing portions 6d are pressed during the pressing operation. Pressing tilted upward, even if the turning torque is applied to the push button switch when the external connection terminals 2a and 3a are used as the fulcrum, the foot 7c is firmly soldered, so that the push button switch can be prevented from peeling. In this configuration, since 9596l.doc -15-1238426 is formed between the leg portion 7c and the side surface of the casing 1, a gap S 'is formed, so that Tan Xi 9 can be soaked from both sides of the plate surface of the leg portion and soldered. 'Thus, soldering can be performed firmly, and at the same time, solder can be prevented from penetrating into the inside of the switch through the chattering portion 7c and the side surface of the casing 1. S shown in FIG. 8 is provided on the cover body between the clamps. The upper and lower plate portions of 7 are formed on the both sides in the vicinity of the oblique sheet, and elongated ribs 7f (deformation preventing portions) are formed along the operation direction of the operation member 6 by protrusions and the like. ^ The ribs 7f are formed on the cover, and the cover 7 is difficult. Shape, it is possible to simply form the deformation preventing portion without adding other components, so that the cost can be reduced. In addition, 'shown in FIG. 9' will be from the two side portions of the cover body 7 to the two side faces of the casing. The head end of the leg portion 70 formed by the extension is bent inward to provide locking pieces 7g, and locking grooves ld are provided on both sides of the housing 1. In addition, 'the locking pieces 7g and Locking and locking can prevent the center of the upper plate portion 7a from bulging upward, and the lid body 7 is difficult to deform. Similarly, the deformation preventing portion can be simply formed without the addition of other components, so that it can be inexpensively realized. At the same time, the locking piece of the foot part can be used to securely lock the cover body 7 with the housing 1. Moreover, in the case of δH, it is not necessary to solder the leg part 7C of the cover body 7 to the surface-mounting substrate. 8 on 'may be soldered only to the external connection terminal core 3a on the surface-mounting substrate 8. According to the embodiment of the present invention described above, the operation member 6 is pressed with the pressing operation of the operation member 6 by the pressing operation 6d. The action part is centered by the inclined piece 7e on the cover body 7.
