The switching contact 37 is in elastic contact with the inner bottom surface 3 1 a, and forms a horizontally long contact portion 37 a, whose front end portion extends parallel to the inner fixed surface to the left wall 3 1 c and the right wall 3 1 e. And the illustrated right end portion of the contact portion 37a is a guide portion 37b bent upward as shown in FIG. 12. Further, the second arm portion 34c becomes a movable contact point and can be connected to and disconnected from the contact point portion 37a. Further, the spring support shaft 33 mounts the torsion coil spring 34 on the lower side, and supports the operation lever 38 on the upper side so that it can rotate freely. This lever has an operation portion 38a located outside the housing 3 in the initial state before operation, and forms a connecting portion 38b to be connected to a portion (not shown) supported by the spring support shaft 33. On the opposite side, in the storage portion 31b, a spring pressing portion 38c capable of pressing the second arm portion 34c of the torsion coil spring 34 is formed. In the conventional switch device, as shown in FIG. 10, the operation portion 38a is located outside of the housing 3 in the initial state before the operation operation of the operation lever 38 is performed. In addition, the second arm portion 34c of the torsion coil spring 34 is located on the inner surface 3 1 a of the bottom plate 31 d, and is in elastic contact with the spring pressing portion 3 of the operation lever 38. In the initial state before the rotation operation of the operation lever 38, as shown in Fig. Π, the second arm 34c leaves the switching contact 37 and enters a switch-off state.

Therefore, the operation part 5e of the operation lever 5 receives an elastic force in the clockwise direction of the arrow D, so that the stopper part 5h and the housing ㈤ stop. When the cover 7 is closed from above the housing 丨 in this state, the engaging hole 7c of the cover 7 is engaged with the hook portion of the housing 丨 and the locking claw of the cover 7 = fixed to the housing! The fixing part. The cover 7 is fixed to the casing, and the switchgear of the present invention is assembled. The following invention is a top-up of the switchgear of the present invention assembled according to the upper assembly method. First, in the initial state shown in FIG. 2 and FIG. 6, the torsion coil spring 6 as a movable contact usually has its first arm ⑼ abutted with the contact portion 2 c of the fixed contact 2, and at the same time, the second The arm portion 6c leaves the contact portions 3g and 3h at the lower and upper portions of the switching contact 变成 and enters a switch-off state. From this initial state 'as shown in FIG. 3, when an operating load in the direction of arrow C is applied to the operating portion of the operating lever 5, the operating lever 5 counteracts the force of the torsion coil spring 6, and supports Shao 4 as the pivot point. Rotate counterclockwise in the direction of arrow c. 疋 stop 5h and leave the stop surface! E, at the same time, the opening angle between the first and second arm portions 6 of the twisted helix spring 6 "reduces, the first The two arm portions 6c make ocean contact with the lower and upper contact portions 3g and 3_guide portions hi as shown in FIG. 7P. In this way, the switch is switched and turned on. When the operation lever 5 is further rotated in the direction of the arrow c from this state, as shown in the figure, the center of the second arm portion of the torsion coil spring 6 is guided by the guide portion ^ and the city center, and is located at a pair of contact portions 3g. , Between 3h. In addition, the butt contact portion 84738 -16- 200307961 3g and 3h are enlarged in the vertical direction by the action of the second arm portion 6c. Then, the operation portion 5 € of the operation lever 5 comes into contact with the outer plate of the second side wall lb, and the operation lever 5 stops rotating. In the full-stroke state of the operating lever 5, as shown in FIG. 2, the second body # 6c is in an inelastic contact and is held between a pair of contact portions & positions, and the switch remains on. Moreover, when the operating force in the direction of arrow c applied to the operating lever 5 is released: under the action of the elastic force of the torsion coil spring 6 itself, the operating lever 5 rotates clockwise, and the second arm portion 6c automatically Returning to the initial state shown in Fig. 2 and Fig. 6, the switch is switched to the off state. "The switch device of this month" When the switch is turned on, the two sides of the outer peripheral portion of the second body 6c, which is occupied by the mobile, are in contact with the pair of contact portions 坫 on both sides in the diameter direction. Since sliding is performed, even if dust or the like intrudes, the contact between the second g 6a and the contact portions 3g and 3h is kept stable. 、，、 苐 身 # 6 c moves on the door of 3 g, 3 h of a pair of contact parts made of metal plate ^ 仃 α, so it does not produce the grinding debris and the like described in the previous example. Make contact more stable. In addition, since the fixed contact 2 and the switching contact 3 are embedded in the casing 1 by using a method such as insert molding, the number of components can be reduced, and the switch contact can be eliminated. Pass position error. In addition, as shown in FIG. 2, the switch device of the present invention includes the housing portion 1 of the housing 1: compared with the connection line ^ between the support portion 4 supporting the operation lever 5 and the switching / contact 3. State of symmetry. For this reason, it is possible to share the outer shape of the main member 1, the switching contact 3, the torsion coil spring 6, and the like, and it is possible to assemble a switch device having an operation lever that can be turned clockwise by the arrow. 84738 -17- 200307961 [Effect of the invention] As described above, the switch device of the present invention has a clip-shaped, butt-contact point portion facing each other. When the operation lever is rotated, the above-mentioned second arm portion and The above-mentioned butt joints are brought into contact with or separated from each other, and can be slid under the elastic contact and clamping state between the above-mentioned butt joints. Therefore, the two positions in the diameter direction of the second arm portion are in elastic contact with the butt joints. Therefore, even if dust or the like invades the inside of the housing, the contact between the second arm portion and the butt contact Shao can be stabilized. Moreover, the switching contacts H of the upper and lower grounds 5 placed side by side in the storage section are buried in the casing to form a whole. Therefore, the number of components can be reduced 'to provide a switchgear with good assemblability. In addition, the operation lever is supported by a support portion formed in the storage portion and can rotate freely. Furthermore, the windings of the torsion coil spring are stored in a spring storage portion formed around the support portion. The torsion coil spring is assembled in a state where the torsion coil spring is installed in the operating lever, and a switch device that can be easily assembled can be provided. In addition, the upper four pairs of contact portions of the switching contact portion form a horizontally long & parallel to the inner surface of the storage portion, and the first portion of the torsion coil spring held by the pair of contact points in an elastic contact state. The 2 arms can slide in a direction parallel to the upper surface of the upper f. Therefore, by using metal: to open: into-butt contact point 'the elastic contact and clamping of the second arm, anti-slavery order' It can still reduce the wear of a pair of contact points and provide a switching device. In addition, since the switch 84738 -18- 200307961 is turned on while the second arm portion slides between the butt contact portion, the switch device is turned on. It can provide a wide operating range. The operability of the housing is 4 丄 M 1 牙 less than the pull point of the switch supporting the operation lever. The connection line between the red and the red is generally symmetrical, so the main components are shared.
