As a result, the operation knob 70 is swingably supported with respect to the knob main body 63 and, at the same time, when the operation knob 70 swings, the connecting member 260 slides in the connecting member guide portion 65 in a linear direction. . At this time, the shaft 261 of the connecting member 260 moves in a linear direction (longitudinal direction) in the shaft engaging portion 79 while relatively rotating in the shaft engaging portion 79 of the operating knob 70, so that the operating knob 70 Is smoothly converted into a linear motion of the connecting member 260. Here, the shaft 261 and the shaft engaging portion 79 constitute a motion direction conversion connecting portion that converts the swinging motion of the operation knob 70 into the linear motion of the connecting member 260.

  Next, while placing the lower surface of the knob case 61 to which the operation knob 70 and the like are mounted on the operation knob body mounting portion 49 of the upper case 40, one surface of the connecting member guide portion 65 is placed on the upper surface plate 41. At that time, the attachment portion 267 of the connection member 260 is engaged with the connection member attachment portion 103 of the connection member attachment portion 101 of the slide member 100 protruding from the opening 47 of the upper case 40 by a snap-in method. . A portion where the connecting member attaching portion 103 and the attaching portion 267 are engaged is referred to as an engaging portion. At this time, the connecting member guide portion 65 and the slide member 100 are arranged such that their longitudinal directions (moving directions) face the same direction, and a part of them is located in parallel. At this time, the position of the mounting hole 51 of the operation knob body mounting portion 49 and the position of the screw insertion portion 69 of the knob case 61 coincide with each other, so that the screws 290 are screwed in from the mounting hole 51 side to fix them together. Thereby, the swing switch 1 is completed. The above assembling procedure is an example, and it goes without saying that the assembly may be performed using other various assembling procedures.

  At this time, as shown in FIG. 1, the front end surface of the protruding portion 113 of the slide member 100 abuts or approaches the upper surface plate 41 of the upper case 40. At the same time, the front end surface of the coil spring 280 is elastically contacted with the upper surface plate 41 of the upper case 40, whereby the operating body 210 is pressed toward the movable contact body 170, and the contact portion a on the outer peripheral surface of the rotating body 240 is Elastically touch the surface. FIG. 1 shows a state in which the slide member 100 is moving upward, and the two operation bodies 210 are moved in the same direction (the rotation body 240 of the rotating body 240) by the pressing portions 111 of both operation body insertion portions 105 provided on the slide member 100. The abutting portion a is inclined in a direction in which a position away from the movable contact 181 is seen from a portion of the movable contact body 170 supported by the movable contact body support 150. At this time, the contact locking portion 173 of the movable contact body 170 contacts the bottom surface of the storage portion 11 of the case 10, and the movable contact body 170 is held at this position and is stationary. Therefore, any movable contact 181 is located away from the fixed contact 141, and any terminal portion 135, 161 is in an OFF state.

  When the upper surface on the side where the operation knob 70 is lifted is pressed in the direction of arrow G shown in FIG. 1, the operation knob 70 rotates about the rotation shaft 77 and rotates (swings). The shaft 261 of the connecting member 260 moves in a linear direction (longitudinal direction of the shaft engaging portion 79) while relatively rotating inside, so that the swinging motion of the operation knob 70 is connected to the connecting member 260 and this. Is converted into a linear motion of the slide member 100. Then, the linearly moving slide member 100 moves linearly downward as shown in FIG. 1, and at this time, the pressing portions 111 of both operation body insertion portions 105 simultaneously lower the outer peripheral side surfaces of the switch operation bodies 220 of both operation bodies 210. When pressed in the direction, both operating bodies 210 swing about the swing shaft 223, and move while the front contact portion a contacts the surface of the movable contact body 170. At the stage beyond the support portion 153 of the body support 150, the movable contact body 170 rapidly swings around the support portion 153 due to the elastic force of the coil spring 280, and both the movable contacts 181 are simultaneously fixed to the two fixed contacts. 141 and the terminals 135 and 161 are turned on. When the operation body 210 swings, the swing shaft 223 moves in the linear direction in the shaft locking portion 19 of the case 10 at the same time. Needless to say, when the upper surface of the operation knob 70 on the side lifted by the above operation is pressed, the operation returns to the state shown in FIG. 1 by the reverse operation to that described above, and the terminal portions 135 and 161 are turned off.

  As described above, according to the swing switch 1, the switch case 10 (and the upper case 40), the slide member 100 installed in the switch case 10 so as to be linearly movable, and the slide member 100 attached to the switch case 10. The pair of fixed contact bodies 130 and the movable contact body support bodies 150 installed in series along the linear movement direction are supported by the movable contact body support bodies 150 so as to be swingable, and the fixed A pair of movable contact members 170 having a movable contact 181 that contacts and separates from the fixed contact 141 provided on the contact member 130, and swings around the swing shaft 223 installed in the switch case 10 and at the tip contact portion a. Moves while abutting on the surface of each movable contact body 170, and a pair of operation bodies 210 that swing the movable contact body 170, and the slide member 10. The operation knob 70 is installed at a position away from the slide member 100 along the linear movement direction, and is supported so as to be swingable about the rotation shaft 77, and the operation knob 70 and the slide member 100 are connected to each other. And a connecting member 260 that converts the swinging motion of the slide member 100 into the linear motion of the slide member 100, and both the operating bodies 210 are simultaneously driven in the same direction by the slide member 100 that linearly moves. The operating body 210 is simultaneously swung, and the contact portions a are simultaneously moved on the surfaces of the two movable contact bodies 170 to swing both the movable contact bodies 170 so that the two sets of the movable contact 181 and the fixed contact 141 are simultaneously moved. It is comprised so that it may contact / separate.

  According to this oscillating switch 1, each of the two sets of the fixed contact body 130, the movable contact body support body 150, and the movable contact body 170 (these three parts are referred to as “switch body”) are arranged in series (linearly). Therefore, the dimension in the thickness direction (the swing axis direction of the operation knob 70) can be reduced. At the same time, since the operation knob 70 is installed at a position away from the slide member 100 along the linear movement direction of the slide member 100, the slide member 100 and the switch main bodies 130, 150, and 170 extend in the back direction when viewed from the operation knob 70 side. Placed in. That is, the projected area of the swing switch 1 when the operation knob 70 is viewed from above can be reduced. Therefore, when the swing switch 1 is attached to a member to be attached such as the outer case 300, other electronic components can be installed close to the vicinity of the periphery where the operation knob 70 of the member to be attached is installed. Integration of various electronic components to be installed is also possible.

  The connecting member 260 has a substantially linear shape, and one end of the connecting member 260 is a motion direction conversion connecting portion (consisting of a shaft engaging portion 79 and a shaft 261) that converts the swinging motion of the operation knob 70 into the linear motion of the connecting member 260. The other end side is engaged with the slide member 100 by an engagement portion (consisting of the connection member attachment portion 103 and the attachment portion 267) that directly transmits the linear motion of the connection member 260 to the slide member 100. ing. As a result, the swinging motion of the operation knob 70 can be easily converted into the linear motion of the slide member 100 with a simple structure at the connecting portion between the two, and the on / off operation of the pair of switch bodies 130, 150, 170 can be reliably performed simultaneously. Can do.

  Further, since the linear movement of the connecting member 260 is guided by the connecting member guide portion 65 covering the connecting member 260, the straightness of the connecting member 260 is further improved, and the on / off operation of the pair of switch bodies 130, 150, 170 is performed. Can be performed more reliably. Further, since the connecting member guide portion 65 and the slide member 100 and a part thereof are arranged in parallel, the dimension in the depth direction of the swing switch 1 can be shortened. In other words, the length of the connecting member guide portion 65 can be increased without increasing the dimension of the swing switch 1 in the depth direction, and the straightness of the connecting member 260 can be further improved. Further, since the engaging portion including the connecting member attaching portion 103 and the attaching portion 267 is disposed in the vicinity of the center of the slide member 100, substantially the same force can be applied to the pair of operating bodies 210, and the pair can be smoothly and well balanced. The operating body 210 can be driven.

  Further, each operating body 210 is installed in the switch case 10 so as to be swingable about the swing shaft 223 and so that the swing shaft 223 itself can move in a linear direction, and is directed toward the contact portion a by the coil spring 280. Therefore, the operation body 210 can move smoothly while contacting the surface of the movable contact body 170. On the other hand, the slide member 100 is provided with the operation body insertion portion 105 that is engaged by inserting each operation body 210, so that the operation member 210 can be smoothly operated and driven by the slide member 100.

With this configuration, as indicated by phantom lines in FIG. 14, the terminal portions 135-2 and 161-2 are inserted into the small holes provided in the printed circuit board 400-2 and soldered, whereby The dynamic switch 1-2 can be attached to the printed circuit board 400-2. Therefore, as described above, the swing switch 1-2 can be fixed without providing the bullet locking portion 73 on the knob case 61, and the outer case 300-2 is placed over the operation knob body 60-2. By doing so, the operation knob body 60-2 can be exposed and installed from the swing switch insertion hole 301-2. Of course, the knob case 61-2 may be further provided with a bullet locking portion to directly fix the swing switch 1-2 and the exterior case 300-2. Further, for example, a board mounting piece is projected from the upper case 40-2 of the swing switch 1-2, and the swing switch 102-2 is printed by locking the board mounting piece to the printed circuit board 400-2. You may attach to the circuit board 400-2.

  As another method of attaching the swing switch to the outer case, for example, a mounting part is provided on the chassis separately installed on the back side of the outer case so as to protrude outward from the upper case. A screw insertion hole may be provided, and the mounting portion may be fixed to the chassis by fixing means such as screwing.

  17 and 18 are views showing a fixed contact body 130B and a movable contact body support 150B used in still another embodiment of the present invention, respectively. FIG. 17 (a) is a front view of the fixed contact body 130B. 18B is a right side view of the fixed contact body 130B, FIG. 18A is a front view of the movable contact body support 150B, and FIG. 18B is a right side view of the movable contact body support 150B.

Items other than those described below are the same as those in the embodiment shown in FIGS. The fixed contact body 130B and the movable contact body support 150B are different from the fixed contact body 130 and the movable contact body support 150 shown in FIGS. 6 and 7 in place of the terminal portions 135 and 161 for tab terminals. In addition, terminal portions 135B and 161B having a lead wire soldering terminal configuration having lead wire mounting holes 139 and 165 in the vicinity of the center are used. The lead wire mounting holes 139 and 165 have a shape in which two circles having a large diameter and a small diameter are overlapped, and the lead wire is easily attached. However, other various shapes may be used. These terminal portions 135B and 161B are inserted between the ends of the flexible lead wires into the lead wire mounting holes 139 and 165 and wound, and the wound portions are soldered to each other (the fixed contact body 130B and the lead wires). Between the wires and between the movable contact body support 150B and the lead wire) are electrically and mechanically connected. When this connection structure is used, the swing switch cannot be mounted on the printed circuit board.
