Wherein the rear end 11 can be fitted into a wall, while the middle frame 12 is close to the outside of the wall. The rear end 11 has a cavity formed therein, in which a contact of a switch, a driving mechanism and the like can be disposed, and the middle frame 12 extends outward along the periphery of the rear end 11 on a side of the rear end 11 close to the outer wall surface.

As shown in fig. 2, the middle frame 12 is formed with an opening 123 communicating with the cavity; the middle frame 12 is provided with at least one first mounting hole 121, and the first mounting hole 121 is configured to allow a nut of a screw to pass through in a direction parallel to the opening 123. In this embodiment, the base 1 reduces the switch assembly process by an integrated design.

As shown in fig. 3, the metal bracket 2 includes a frame 21, the frame 21 is detachably connected to the base 1, a connection port 211 in the middle of the frame 21 passes through the rear end 11 to abut against the middle frame 12, and at least one second mounting hole 212 corresponding to the at least one first mounting hole 121 is further disposed on the frame 21; the second mounting hole 212 is for the nut of the screw to abut against the periphery thereof. In this embodiment, the installation of the switch can be completed only by installing the metal bracket 2 on the wall through the screw, so that the installation process is simple, and the screw is only in direct contact with the metal bracket 2 with high strength, thereby greatly reducing the problems of the reduction of the stability of the function and the like caused by the deformation of the shell of the switch in the installation process. Wherein, the switch in this embodiment can make its installation link more high-efficient and the product function of installation back switch more reliable owing to used above-mentioned shell. Wherein, the metal support 2 is extruded by the screw and deformed, so that the whole functions of the switch and the socket are not influenced.

Preferably, in conjunction with fig. 2 and 3, the hole wall of the first mounting hole 121 may extend to the periphery of the second mounting hole 212. Therefore, all parts of the middle frame 12 can be tightly attached to the metal support 2, so that the connection between the metal support 2 and the base 1 is tighter, the hole wall of the first mounting hole 121 can also play a role in guiding the screw, the screw can be smoothly mounted on the second mounting hole 212, and the gap between the middle frame 12 and the metal support 2 can be prevented from falling.

Preferably, one surface of the frame 21 facing the middle frame 12 may be configured to be in concave-convex fit with the opposite surface of the middle frame 12, so that the frame 21 may be directly used as an outer lining of the middle frame 12, and the whole of the outer shell is protected on the premise of keeping the shape of the outer shell unchanged.

Preferably, the metal bracket 2 can be clamped on the rear end 11 of the base 1 or the middle frame 12, and the metal bracket 2 can also be clamped with the rear end 11 of the base 1 and the middle frame 12 at the same time.

For example, referring to fig. 2 and 3, in the embodiment that the metal bracket 2 is connected to the middle frame 12, two opposite sides of a surface of the middle frame 12 facing away from the opening 123 are respectively formed with a mounting groove 122, and each mounting groove 122 has an inner wall on which a first buckle 1221 is disposed. It should be noted that the mounting grooves 122 on the two sides may be one connected mounting groove 122, or a plurality of mounting grooves 122 are respectively disposed on the two sides, and the function of disposing the first fastener 1221 in this embodiment can be achieved. The metal bracket 2 is provided with a connecting arm 22 which can extend into the mounting groove 122, and the connecting arm 22 is provided with a first bayonet 221 which is clamped with the first buckle 1221. The metal bracket 2 is clamped with the first buckles 1221 of the middle frame 12 through the first bayonets 221, and the metal bracket 2 can be connected to the base 1. The first fastener 1221 may be disposed inside an outer sidewall of the mounting groove 122.

As shown in fig. 3, in an embodiment where the metal bracket 2 is connected to the rear end 11, two opposite sides of an outer wall of the rear end 11 are respectively provided with a second buckle 111; a surrounding plate 23 extending along the outer wall of the rear end 11 is further formed at the connecting port 211 of the frame 21, and a corresponding number of second bayonets 231 engaged with the second bayonets 111 are formed on the surrounding plate 23. The metal bracket 2 is clamped with the plurality of second clamping buckles 111 on the middle frame 12 through the plurality of second clamping openings 231 on the metal bracket 2, and the metal bracket 2 can be connected to the base 1.
