They are only one of the implementation methods of the utility model and are not a limitation on its implementation method.

[0027] This embodiment provides a switch, such as Figures 1 to 5 As shown, it includes a base body 1, and at least one set of switch components 2 is arranged on the base body 1. The switch components 2 include a first contact pin 21, a second contact pin 22, a metal support plate 23 electrically connected to the first contact pin 21, and a metal seesaw 24 arranged between the first contact pin 21 and the second contact pin 22. The base body 1 is provided with two mounting grooves 11 located on both sides of the metal seesaw 24, and the middle part of the metal seesaw 24 is provided with a plug-in protrusion 241 extending to both sides and used for inserting into the mounting groove 11, as shown in FIG. Figure 3 and Figure 4As shown, vertically arranged mounting grooves 11 are provided at both sides of the metal rocker plate 24, and the plug-in protrusions 241 on both sides of the metal rocker plate 24 are inserted into the mounting grooves 11, so that the metal rocker plate 24 can slide up and down relative to the seat body 1 and can swing circumferentially around the plug-in protrusions 241, and the free end of the metal support plate 23 is provided with a support portion 230, and the support portion 230 is located below the middle of the metal rocker plate 24, so as to prevent the metal rocker plate 24 from sliding downward, so that the metal rocker plate 24 can only swing relative to the seat body 1, and the seat body 1 is provided with a lever member 3 for manual manipulation and capable of driving the metal rocker plate 24 to swing, the second contact foot 22 is connected to a static contact 25, and the metal rocker plate 24 is connected to a moving contact 26 at one end close to the static contact 25, which can abut against the static contact 25 after the metal rocker plate 24 swings, and the seat body 1 is provided with a positioning structure 12 for fixing the support portion 230 to prevent the support portion 230 from shaking. During operation, the metal seesaw 24 is pushed to swing by manually toggling the lever 3. When the metal seesaw 24 swings and the static contact 25 and the moving contact 26 come into contact, the first contact pin 21, the metal support plate 23, the metal seesaw 24, and the second contact pin 22 are connected in sequence to realize the connection of the circuit. When the metal seesaw 24 swings and the static contact 25 and the moving contact 26 are separated, the circuit is disconnected. The positioning structure 12 can firmly fix the support part 230. The support part 230 will not shake when the metal seesaw 24 swings. The structure is stable, reliable and simple.

[0028] As a preferred solution of this embodiment, Figures 2 to 5 As shown, the free end of the metal support plate 23 is provided with a folding plate 231, and the support portion 230 is formed by bending and folding the folding plate 231 downward, and the positioning structure 12 includes a first supporting surface 121 matched with the end surface of the folding plate 231, and a second supporting surface 122 matched with the surface of the folding plate 231. Figure 6 As shown, the folding plate 231 has an end surface 231a and a surface 231b. Figure 2As shown, when the folding plate 231 is placed on the positioning structure 12, the first support surface 121 is in close contact with the end surface 231a of the folding plate 231, and the second support surface 122 is in close contact with the surface 231b of the folding plate 231. In this embodiment, the second support surface 122 and the surface 231b of the folding plate 231 are not flat but slightly inclined. As a preferred solution, the second support surface 122 can be designed to be flush with the surface 231b of the folding plate 231, that is, the two are flat. In this way, the support portion 230 is formed by folding the free end of the metal support plate 23, and the positioning structure 12 is composed of two V-shaped first support surfaces 121 and second support surfaces 122. The support portion 230 is positioned and matched by the inclined surface to form a stable and firm positioning, so that the metal seesaw 24 has a stable and reliable support, and the structure is simple and reliable, easy to manufacture, and saves production costs.

[0029] As a preferred solution of this embodiment, Figure 2 and Figure 3 As shown, the lever member 3 is rotatably connected to the seat body 1, and the lever member 3 is provided with a sliding hole 31 opening downward, and a top column 32 is provided in the sliding hole 31, and an elastic member 33 is provided between the top column 32 and the bottom of the sliding hole 31, and the lower end of the top column 32 abuts against the middle of the metal rocker 24, so that when the lever member 3 is rotated, the lower end of the top column 32 moves between the two sides of the middle of the metal rocker 24, thereby promoting the swing of the metal rocker 24. As a preferred embodiment, Figure 2 , Figure 4 and Figure 5 As shown, the metal seesaw 24 is provided with a curved section 242 that is bent and tilted upward on the side close to the moving contact 26, and the moving contact 26 is arranged at the end of the curved section 242. The metal seesaw 24 is provided with a horizontally arranged flat section 243 on the side away from the moving contact 26. In this way, when the lower end of the top column 32 moves to the curved section 242, the curved section 242 of the metal seesaw 24 can swing downward quickly, so that the static contact 25 and the moving contact 26 are quickly separated, thereby improving the sensitivity. The other side of the metal seesaw 24 is set to the flat section 243. When the lower end of the top column 32 moves to the flat section 243, the top column 32 extends downward and presses the flat section 243 downward, so that the metal seesaw 24 swings and the static contact 25 and the moving contact 26 are in contact with each other. Of course, this side can also be set to an upward curved structure symmetrical to the curved section 242.

[0030] As a preference, Figure 3 and Figure 4As shown, the seat body 1 is provided with two groups of on-off components 2, and the two groups of on-off components 2 are symmetrically arranged. The lever member 3 is provided with two sliding holes 31, and the sliding holes 31 are each provided with a top column 32 and an elastic member 33. The two top columns 32 are respectively arranged corresponding to the metal seesaws 24 of the two groups of on-off components 2, and the lower ends of the two top columns 32 respectively abut against the middle of the metal seesaws 24 of the two groups of on-off components 2, so that when the lever member 3 swings, the two metal seesaws 24 are pushed to swing at the same time.

[0031] In order to reduce the friction between the top column 32 and the metal rocker plate 24 , preferably, a circular arc surface 321 is provided at the lower end of the top column 32 .

[0032] As a preferred solution of this embodiment, Figures 2 to 6 As shown, a positioning hole 232 is provided in the middle of the metal support plate 23, and a positioning column 13 passing through the positioning hole 232 is provided on the base body 1. The metal seesaw 24 is located above the positioning column 13 at the end away from the static contact 25. The positioning column 13 plays a role in fixing the metal support plate 23 to prevent the metal support plate 23 from horizontal displacement or swinging. The positioning column 13 is located below the flat section 243 of the metal seesaw 24 to play a limiting role, so that the metal seesaw 24 is hindered by the positioning column 13 during the swinging process, and the swinging amplitude is limited, thereby preventing the metal seesaw 24 from swinging too much.

[0033] In detail, Figure 2 and Figure 3 As shown, the seat body 1 is composed of a base 101 and an upper cover 102. Preferably, the upper cover 102 is detachably connected to the base 101, and adopts a multi-button assembly and a mechanical anti-slip design to avoid the defects and quality risks of the locking screw structure. As a preferred solution of the detachable connection structure, Figure 3 As shown, a snap hole 103 is provided on the side of the base 101 , and a snap-in protrusion 104 for snapping into the snap hole 103 is provided on the inner wall of the upper cover 102 .

[0034] Preferably, the metal seesaw plate 24 and the metal support plate 23 are copper metal sheets.

[0035] The above is only an embodiment of the utility model, and the common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the utility model, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
