(I) and then the pushing block is cut and separated from the supporting rod of the material belt.
2. The push button manufacturing method of a slide switch according to claim 1, wherein: the terminal pin in the material belt is integrally formed to form the pushing block by utilizing a die.
3. The push button manufacturing method of a slide switch according to claim 1, wherein: the liquid insulating material injected into the injection port of the mold is plastic, rubber or acryl.
4. The push button manufacturing method of a slide switch according to claim 1, wherein: a plurality of grooves are formed in the surface of a base of the material pulling mechanism corresponding to the positions of the plurality of material pulling pins, the material pulling pins are arranged in the grooves, and elastic bodies are arranged between the material pulling pins and the bottom surfaces of the grooves.
5. The push button manufacturing method of a slide switch according to claim 1, wherein: the material pulling mechanism is characterized in that a plurality of accommodating grooves are concavely formed in the positions, corresponding to the plurality of material pulling pins, of the bottom surface of the material pulling block, the plurality of material pulling pins are accommodated in the plurality of accommodating grooves, an elastic body is arranged between each material pulling pin and the bottom surface of the accommodating groove, when the material pulling pins are separated from the limitation of the material belt holes, the elastic bodies are in a compressed state, and when the plurality of material pulling pins move to the positions of the plurality of material belt holes on the other side along with the transverse direction of the material pulling block, the elastic bodies can generate elastic recovery, so that the material pulling pins are driven to be inserted into the material belt.
