Because it is formed, it is not necessary to perform centralized processing on the central contact 6 and the general contact 8 like a conventional push button switch, that is, it can be formed on a thin plate, so the manufacturing process of the push switch can be simplified. In addition, since the fixed contact bodies 1, 4 and the spacer body 16 are formed in a flat thin plate shape, it is possible to easily and extremely accurately form the difference in thickness of the plate constituting the impact amount of the push button switch.

In addition, since the positioning operation can be accurately performed by an automatic assembly machine, materials such as a thin metal plate having a thinner plate thickness can be used, which has a thinning effect. In addition, since the first iron ring material formed by drilling the fixed contact body 14 is drilled and the third iron ring material formed by drilling the movable contact body 28 is the same material, a single iron ring material is used. When drilling the fixed contact body 14 and the movable contact body 28, only two compressive molds and the above-mentioned mold for the partition body 16 are required. Therefore, the production cost of the mold can be reduced, and the mold production can be shortened. time. [Effects of the Invention] The push button switch of the present invention as described above is made of a thin metal plate composed of an insulated circuit board, a central contact fixed to the green circuit board, and a first connection terminal connected to the central contact. The fixed contact body and the partition plate which is arranged around the central contact similarly on the aforesaid green circuit board are thicker than the thickness of the central contact, and a dome-shaped movable contact covering the central contact is connected to the first contact. 2 The movable contact body made of a thin metal plate composed of the connection ends is formed by contacting the lower part of the outer peripheral edge of the movable contact with the partition, so that the central contact and the movable contact are spaced a certain distance from each other on the insulated circuit board The second connection terminal of the movable contact body is fixedly installed on the upper side, and the movable contact and the second connection terminal are integrally formed, so that contact separation does not occur when the movable contact is operated, and this button is surely used. The switch is in the ON state.

Description of the invention (10 ) (Please read the precautions on the back before filling out this page) and 'As long as the central contact and partition made of a thin metal plate are directly fixed to the insulating circuit board, the board between the central contact and the partition can be used The difference in thickness results in an accurate contact segment difference, so there is no need to concentrate the contact. In addition, a fixed contact body having a central contact and a first connection terminal is drilled to form a first iron ring material, a separator body having a partition is drilled to form a second iron ring material, and the movable body is movable. The contact body is drilled to form the third iron ring material, and then the stack is sequentially positioned. On the upper and lower sides of the stacked first, second, and third iron ring materials, the insulating plate and the insulating circuit board are respectively held and fixed. Then, the unnecessary parts of the first, second, and third iron ring materials are cut away, and the positioning operation of each of the first, second, and third concrete ring materials can be accurately performed, so a thin metal plate, etc. can be used.
