れらの工程が連続的に加えられるものである。 Next, as shown in FIG. 4, an elongated metal belt 7 made of a highly conductive metal plate such as copper and having a width of W 2 is prepared. This metal belt 7 is metal belt 1
Similar to the above, a long item is wound onto a reel. The width W 2 of the metal belt 7 is set larger than the width W 1 of the metal belt 1. Note that the material of the metal belt 7 does not need to be highly elastic like the metal belt 1, and may be thicker than the metal belt 1. After that, perform punching work and make pilot hole 1.
0a and a fitting hole 8a for attaching the fixed contact 13, the fixed contact is fitted into the fitting hole 8a and caulked, and the fixed contact 13 is caulked as shown by the dotted line in FIG. The fixed contact 13, like the movable contact 5, is made of a noble metal such as gold or silver.
In the next punching process, the fixed contact part 8, the movable contact part 9, and the bridge part 10 are formed, as well as the terminal part 11 connected to the fixed contact part 8 and the terminal part 12 connected to the movable contact part 9. In the final punching step, a cut and raised piece 9a for attaching the movable contact plate 6 to the movable contact portion 9 is provided. In addition, terminal part 1
The distance W 3 between the inner sides of the metal belts 1 and 12 is wider than the width W 1 of the metal belt 1 . When the punching process is completed, the metal belt 7 that has been punched out is placed in a synthetic resin casting machine for each appropriate length, and a frame 14 made of synthetic resin is attached as shown in FIG. 2 steps). Through this casting process, the fixed contact part 8 and the movable contact part 9 are formed into this frame 14.
are fixed together. FIG. 6 is a perspective view showing the metal belt 7 that has been subjected to a casting process. 6th
As is clear from the figure, the length L 1 of the frame 14 is
The distance between the frames 14 is larger than the distance L 2 between the frames 14, and the thickness H 2 of the frames 14 is larger than the thickness H 1 of the actuating portion 6a provided at the tip of the movable contact plate 6. It should be noted that the processing steps of the metal belt 7 consisting of these punching steps and casting steps are sequentially performed while the metal belt is moving through several presses and casting machines.

ておくとよい。 After the processing of the metal belt 1 and the metal belt 7 are completed, they are stacked and integrated. That is, as shown in FIGS. 7 and 8, when the pilot hole 2 drilled in the metal belt 1 and the pilot hole 10a drilled in the metal belt 7 are inserted into the protrusion of the jig and overlapped, the metal The fitting hole 4 of the belt 1 fits into the cut and raised piece 9a of the metal belt 7. In this state, the movable contact plate 6 is fixed to the movable contact portion 9 of the metal belt 7 by bending or crushing the tip of the protruding cut and raised piece 9a (third step). By fixing the movable contact plate 6 to the movable contact portion 9, the movable contact 5 comes into contact with the fixed contact 13, and the actuating portion 6a is located between the frames 14. The terminal portions 11 and 12 are located outside the metal belt 1. In order to ensure this contact, it is preferable to bend the movable contact plate 6 of the metal belt 1 slightly toward the fixed contact portion 8 in advance.

る。 When the overlapping of the metal belts 1 and 7 is completed, cut along the line 15 shown in FIGS. 7 and 8. By this cutting, unnecessary portions of the metal belt 1 form a ladder shape and are separated from the movable contact plate 6. Further, when the wires 16 and 17 portions of the terminal portions 11 and 12 are cut, the contact member 18 as shown in FIG. 9 is separated. The terminal portion 11 of the contact member that has become a single unit in this way is connected to the fixed contact 13, and the terminal portion 11 is connected to the fixed contact 13.
2 is connected to the movable contact 5. This contact member 1
Although not shown in the figure, the switch 8 is housed in a switch case, and its terminal portions 11 and 12 protrude outward from the case, and the actuating portion 6a faces an actuating member connected to the push button. Then, the push button is pressed and the actuating member contacts and presses the actuating part 6a,
The movable contact 5 separates from the fixed contact 13 and the switch is turned off. When the press of the push button is stopped, the operating member is returned by the return spring and separated from the operating portion 6a, so that the movable contact 5 and the fixed contact 13 are assembled as a push button switch so that they come into contact again.

ある。 As described above in detail with respect to one embodiment, according to the method for manufacturing a contact member of the present invention, the first
a first step of continuously forming a plurality of tongue-shaped movable contact plates on a metal belt; and a plurality of fixed contact portions and movable contact portions corresponding to the movable contact plates on a second metal belt. a second step of casting a synthetic resin frame to form the contact portions and fixing the contact portions together; and a second step of overlapping the first and second metal belts and fixing the movable contact plate to the movable contact portion. A plurality of contact members can be formed simultaneously through the three steps. This not only makes it easier to manufacture a contact member that incorporates a fixed contact and a movable contact used as a push button switch, but also
Automatic manufacturing of contact members is possible. Since the contact member consisting of multiple pieces can be formed into a belt shape, it can be transported by winding it in a loop shape.
Storage is also easy. Since it is only necessary to separate the contact members by the required number when necessary, the contact portion between the movable contact and the fixed contact is not damaged due to repeated transportation as in conventional devices, and the yield of the switch is improved. Further, since the first metal belt has the terminal portion extending from the side, and the portion that was conventionally discarded is used as the terminal portion, there are advantages such as a good material yield.
