ていた。However, in the above-described conventional terminal crimping structure, the portion of the terminal 20 projecting from the terminal mounting hole 26 of the mounting member 25 is subjected to the stress or impact during the crimping, and is indicated by the arrow B in FIG. Since it is easy to tilt or bend in the direction, there is a risk that the terminal position may be misaligned or the contact position may be displaced by inducing the tilt of the contact 21, which makes it difficult to obtain high reliability. Further, in the conventional structure, since the pair of step portions 23 provided on the terminal 20 are used as the caulking margin, the terminal mounting hole 26 into which the wide portion of the terminal 20 having the step portions 23 is inserted is inserted. The length dimension C must be set to a relatively large value, and the terminal mounting hole 2
Since the vicinity of both ends on the side of the terminal projecting surface 27 of 6 is the caulking portion, it is necessary to secure a long space for caulking and fixing the terminal 20 to the mounting member 25, which deteriorates the space factor and reduces the size of the product. It was a factor that hindered the change.

However, on the inner wall surface of the operating body 8, there is provided a driving projection 8b which can be engaged with and disengaged from the engaging piece 5f of the conductor plate 5, and the driving projection 8b is rotated when the operating body 8 is rotated by a switching operation. 8
While b is engaged with the engagement piece 5f and rotationally drives the conductor plate 5, it is set to cross a plane including the rotation center line of the operating body 8 and the swing fulcrum A of the conductor plate 5. Incidentally, FIGS.
As is clear from the above, when the operating body 8 is rotated about the support shaft 9, the drive protrusion 8b rotationally drives the conductor plate 5 in the opposite direction. The torsion coil spring 7 interposed between the operating body 8 and the conductor plate 5 has the winding portion 7a.
Is elastically contacted with the central portion of the bottom surface of the operating body 8, and the pair of arm portions 7b are elastically contacted with the conductor plate 5 at two positions straddling the swing fulcrum A of the conductor plate 5.

It is incorporated in a state where it is elastically contacted with the central portion of the bottom surface, and when this winding portion 7a is pushed into the operating body 8 from above, the arm portion 7 is
The winding portion 7a is formed in the space 5 of the conductor plate 5 while changing the bending amount of b.
It is designed to move within b. Therefore, when one end of the operating surface 8a is pushed to rotate the operating body 8, the torsion coil spring 7 performs an operation of rotating at a stroke after the winding portion 7a is pushed into the void 5b. Since the conductor plate 5 is rotationally driven in accordance with the operation of the torsion coil spring 7, the conductor plate 5 can be swung with the swing of the operating body 8 about the swing fulcrum A.

オフ状態となる。As a result, in the seesaw switch, when the operator pushes the left end of the operation surface 8a in the figure in the state shown in FIG. 5 and rotates the operation body 8 counterclockwise, the inclination of the operation body 8 is substantially reduced. Torsion coil spring 7 when it reaches 0
Since the height position of the winding part 7a is the lowest and the bending amount of the arm part 7b is the largest at that time, a strong reaction force is felt in the operator's finger, and if the operation surface 8a is further pushed, the winding part 7a is wound. Since the portion 7a rotates in a clockwise direction while raising the height position, and the conductor plate 5 also rotates in a clockwise direction accordingly, the movable contact 6 comes into contact with the fixed contact 3 and is separated from each other as shown in FIG. The central terminal 2 and the fixed contact 3 thus arranged are electrically connected via the conductor plate 5 to be in a switch-on state. Further, when the operator pushes the right end portion of the operation surface 8a in the state shown in FIG. 4 and rotates the operating body 8 in the clockwise direction, a strong reaction force is felt on the operator's fingers by the same operation principle as above. Immediately after being wound, the winding portion 7a immediately rotates counterclockwise, and the conductor plate 5 also rotates counterclockwise accordingly, so that the movable contact 6 is separated from the fixed contact 3 and is in a switch-off state.

The inner wall surface of the terminal mounting hole 1b can receive the stress and impact applied to the periphery of the tongues 2b and 4a during the crimping. There is little possibility that the terminals 2 and 4 will be deformed undesirably at the time of caulking, and therefore, highly reliable caulking and fixing can be performed in which displacement of the terminal position and the contact position is less likely to occur.

となっている。Further, conventionally, since a pair of step portions are provided on the side edge portions of the terminals as a caulking margin, the width dimension becomes large. However, the terminal caulking structure in this embodiment has a tongue corresponding to a caulking margin. Since the pieces 2b and 4a may be provided on the non-peripheral edge portions (inner sides) of the terminals 2 and 4, respectively, the width dimension of each of the terminals 2 and 4 can be set small, so that the length dimension D of the terminal mounting hole 1b can be set. (See FIG. 2) can be set short, and it is not necessary to secure a caulking portion on the bottom surface of the housing 1 which is the terminal projecting surface, and the space factor is good.
