New description: [New technical field] This creation is a type of push switch, especially a switch that is small in size and used in portable electronic devices. [Prior Art] Such a push switch is currently known. As shown in the fourth figure, the push switch 200 includes a base 210, which is an insulated box body, and the center and the periphery of the inner bottom surface 211 are respectively provided. There is a central fixed contact 212 and two peripheral fixed contacts (not shown), and the three fixed contacts 212 are respectively connected with the terminal 214 (two of which are not shown) provided on the outer side; a contact piece 22〇, An elastic conductor is disposed on the inner bottom surface 211 in an upwardly curved shape, and a periphery 222 abuts the two peripheral fixed contacts, and the center point 221 and the central fixed contact 212 are maintained. A certain distance; an operating member 230 is formed by a button 231 and a chassis 232. The button 231 has a cylindrical shape and is disposed at a center point of the chassis 232. The chassis 232 has a rectangular shape and a bottom surface 234 thereof. 5, the 'abutment point 235' is abutted on the center point 221 of the sinuous contact piece 220. The upper cover 240' is overlaid on the top surface 213 of the shoal base 210, and forms an accommodation space for accommodating the The contact piece 220 and the operating piece 23〇, the upper cover 24〇 Is provided with a button hole 241 'slightly larger than a diameter of the button 231, the button 231 protrudes to the button hole 241, and can move freely up and down. The conventional push switch 200' is constructed as described above. When the push switch 2 is soldered to the circuit board 5, as shown in the fourth and fifth figures, a small amount of flux M411652 is along the upper cover 240. The bottom surface 244 and the top surface of the base 2ω are inserted into the base 210, and a top surface of the chassis of the operating member 23 is applied between the top surface of the chassis and the bottom surface 244 of the upper cover 240 to form a viscous substance. The operating member 230 is adhered to the upper cover 240, so that the operating member 23 is difficult to move up and down, and cannot function as a function, and the disadvantage of the button seems to be improved. [New content] W The shortcomings of the above-mentioned conventional presses, the creation of the present invention is provided on the chassis. (4) The face-symmetric pressing switch having four or more isolation protrusions. The push switch can make a point contact between the top surface of the chassis and the bottom surface of the upper cover instead of the surface contact 'and leave a certain space, so that even if a small amount of flux is intruded, the The two sides are in contact with the surface, that is, the operation piece is difficult to move up and down. The push switch of the present invention comprises: a base, an insulated box-shaped body, and a central fixed contact and two peripheral fixed contacts respectively on the inner bottom surface thereof, and the three fixed contacts are respectively arranged on the outer side of the terminal The mechanical contact; the contact piece is an elastic conductive body' which is curved upwardly and is placed on the inner bottom surface of the base, and its periphery abuts against the two peripheral fixed joints, the center point and the center The fixed contact is kept at a fixed distance; an operating member is composed of a button and a chassis, and the button is cylindrically disposed at a center point of the chassis, and the chassis has a rectangular shape Symmetrically, there are four or more isolation protrusions, and an abutment point is disposed at a center of the bottom surface thereof to abut the center point of the contact piece; and an upper cover covers the top surface of the sea base and forms an accommodation space. To accommodate the contact piece and the operating member, a center of the upper cover is provided with a buttonhole, the diameter of which is slightly larger than the straightness of the button
