New description: [New technical field] This creative department is a kind of dust switch, especially related to a push switch for electronic equipment. [Prior Art] Please refer to the type of push-pull switch disclosed in Chinese Patent Publication No. 2708476, which discloses an insulating body formed with a fixed contact and a disk-shaped movable contact fixed contact on the insulating body. When the central mosquito contact that exposes the receiving hole of the insulating body is provided for the guarding, the operator can make a switching action by pressing the movable contact to make contact with the central fixed contact. However, due to the miniaturized structure of such push switches and the characteristics of manual work, when the external soil or the switch itself has dust or debris entering the contact area, it will bring hidden dangers, and the operator encounters this in life. Poor contact is often solved by increasing the pressing force to increase the contact area. It is not known that for the elastic movable contact, the effect of such action on the life and performance is fatal. In view of this, it is necessary to provide a new type of push switch to overcome the above drawbacks. [New content] The technical problem to be solved by this creation is to provide a push switch that ensures reliable electrical connection. In order to solve the technical problems of the solution, the creation of the creation includes an insulating body, a normally open contact fixed to the insulating body, and a movable contact piece located above the normally open contact. When pressed, the movable downward ft is opened. / Contact with the open contact, when the release is released, the movable contact piece is restored to its original state under the elastic action 3 M363062, and the normally open contact is provided with a linear convex portion around the center of the contact area of the movable contact piece. Compared with the prior art, the present invention is provided with a linear convex structure around the movable contact area of the switch, so that the joint region forms a depression around the convex portion. At this time, it is easier to fall into or fall into the lower depression during the pressing process without affecting the normal operation of the switch. [Embodiment] The following is a detailed description of the specific implementation mode of the creation according to the drawings. _ Month to see the sister to the fifth ® ' This creation press M100 includes the insulating body 1, - body molded on the insulating body! The normally open contact 2 and the normally closed contact 3, the curved top movable contact 4 assembled in the insulating body, and the film 5 assembled above the movable contact 4. The insulative housing 1 is provided with a first recessed portion n for accommodating the movable contact piece 4 and a circular second recessed portion 13 which is recessed at a position of the first recessed portion 11 to be integrally formed in the insulating body. The contact point 2 is provided with a circular central contact portion 2, and the central contact portion 21 is received in the second recessed portion 13 and exposed in the first recessed portion n, the second circular recess and the center of the central contact portion 21_ The movable contact piece 4 is in contact with the contact area corresponding to the normally open contact 2 by the downward elastic deformation, that is, the central contact portion 21, and the normally open contact 2 is provided around the center of the central contact portion 21 - a closed line shape Protrusion 211. The normally open contact 2 further includes an abutting blade and a retaining portion 25 disposed on opposite sides of the central contact portion 21, the abutting portion 23 being connected to the central contact portion 21 for transmitting electrical connection, and the retaining portion 25 being disposed at the center The free end of the contact portion 21 is embedded in the insulating body 以 to increase the holding of the central contact portion 21. The central contact portion 21 is connected to the abutting portion 23 and the holding portion 25 on the same plane, and the linear convex portion 211 is punched out of the central contact portion 21, the adjacent 4 M363062, that is, except the linear convex portion 2, the central contact The plane in which the main body connecting portion 25 and the rotating portion μ are located is not punched. Pressing the waste switch 1GG into the step - the body is formed into two normally closed contacts 3 in the first recessed portion η. The two normally closed contacts 3 are located at opposite ends of the same direction of the movable contact 4, When the movable contact piece 4 is inserted into the first recessed portion η, it is normally in contact with the peripheral edge of the curved top movable contact piece 4.
