[0050] Figures 1 to 6 As shown in the prior art panel switch, the thickness of the panel body is L, the thickness of the support is M, and the thickness of the pressing edge of the frame is N. After assembly, the lower end of the panel body is provided with a boss 151 for accommodating the circuit board 18, the boss 151 is attached to the support 12, and the circuit board 18 is generally arranged in the boss 151, so that the circuit board 18 indirectly abuts against the support 12. The support 12 is pressed on the pressing edge 142 of the frame 14, and the support 12 is located above the pressing edge 142, and the space of the avoiding groove 143 of the frame 14 is not utilized, and at this time, the thickness of the panel switch exposed from the wall body 17 is equal to L+M+N, and the overall thickness is large.

[0051] ​The frame 14 has a mounting groove 141 communicating with the accommodating groove 112. The frame 14 is in the shape of a square box, and the mounting groove 141 is a square through hole. The mounting groove 141 penetrates the frame 14 from top to bottom. The inner wall of the mounting groove 141 is provided with a pressing edge 142 for abutting against the wall body 17. The frame 14 is used to enclose components such as the panel body 15, so as to protect the components such as the panel body 15. The panel body 15 is mounted in the mounting groove 141, and the upper end of the panel body 15 is flush with the upper end surface of the frame 14. The lower end of the panel body 15 is provided with a boss 151, and a circuit board 18 (PCB board) is mounted in the boss 151, so that the thickness of the panel body 15 coincides with the thickness of the circuit board 18.

[0052] The mounting process of the panel switch of the present application is as follows: first, the bracket 12 and the base 13 are connected, then the whole composed of the bracket 12 and the base 13 is mounted on the frame 14, and the abutting portion 122 of the bracket 12 abuts against the pressing edge 142 of the frame 14, then the bracket 12, the base 13 and the frame 14 are integrally mounted on the upper box 11, the connecting portion 121 of the bracket 12 is connected with the supporting portion 111 of the box 11 by using the threaded fastener 16, then the panel body 15 is mounted on the frame 14, and finally the whole panel switch is integrally mounted on the wall body 17, the box 11 is located in the box groove of the wall body 17, and the lower end of the frame 14 and the pressing edge 142 in the frame 14 abut against the wall body 17.

[0053] After the panel switch is installed on the wall body 17, the pressing edge 142 is clamped between the abutting portion 122 and the box 11, the abutting portion 122, the pressing edge 142 and the box 11 of the support 12 are sequentially arranged from top to bottom, and the pressing edge 142 abuts the outer side of the wall body 17. The base 13 extends into the accommodating groove 112 through the mounting groove 141. The abutting portion 122 protrudes relative to the connecting portion 121 in a direction away from the bottom wall of the accommodating groove 112, and the abutting portion 122 protrudes upward relative to the connecting portion 121 and abuts the lower surface of the pressing edge 142. The pressing edge 142 extends along the circumference of the connecting portion 121 and forms the avoiding groove 143, and the circumferential extension of the pressing edge 142 can be continuous or intermittent. The connecting portion 121 is downwardly clamped into the avoiding groove 143, and the circuit board 18 abuts the connecting portion 121. When the circuit board 18 is installed on the lower end surface of the panel body 15 and exposed, the circuit board 18 directly abuts the connecting portion 121. In this embodiment, the circuit board 18 is installed in the boss 151 at the lower end of the panel body 15 and is not exposed, and the circuit board 18 indirectly abuts the connecting portion 121 through the boss 151. The connecting portion 121 is downwardly recessed and clamped into the avoiding groove 143 relative to the abutting portion 122. In this way, the connecting portion 121 makes full use of the space of the avoiding groove 143, and the boss 151 can be closer to the bottom wall of the box 11 when abutting the connecting portion 121. The panel body 15 as a whole is closer to the bottom wall of the box 11, thereby reducing the thickness of the exposed wall part of the panel switch. The support portion 111 is connected with the connecting portion 121 to realize the connection and fixation of the support 12 and the box 11.

[0054] With reference to Figure 6 After the panel switch is installed, the connecting portion 121 is recessed downward, and the boss 151 of the panel body 15 is attached to the connecting portion 121. Since the connecting portion 121 is recessed downward relative to the abutting portion 122 and clamped into the avoiding groove 143, the space of the avoiding groove 143 is fully utilized, and the upper end surface of the panel body 15 is closer to the wall surface of the wall body 17, thereby reducing the thickness of the exposed wall part of the panel switch. Specifically, the thickness of the panel body 15 is X, the thickness of the connecting portion 121 of the support 12 is Y, and the thickness of the pressing edge 142 of the frame 14 is Z. Among them, Y+Z partially overlap, that is, the connecting portion 121 and the pressing edge 142 at least partially overlap in the thickness direction, thereby reducing the thickness of the panel switch exposed to the wall body 17, and reducing the space occupied by the panel switch exposed to the wall body 17.

[0055] The application solves the problem of thickness increase caused by the thickness of the support 12 and the thickness of the pressing edge 142 of the frame 14 in the prior art. The application makes full use of the space inside the panel switch, so that the thickness occupied by the connecting part 121 of the support 12 coincides with the thickness of the pressing edge 142 of the frame 14, and the panel body is closer to the bottom wall of the cassette 11 and the wall surface of the wall 17. At the same time, the abutting part 122 formed by bending the four peripheral edges of the support 12 upward has higher structural strength than the planar design structure, and can further increase the structural strength of the support 12.

[0056] Optionally, the panel switch further comprises a threaded fastener 16. The panel body 15 is installed after the frame 14, and a containing space 19 is formed between the panel body 15 and the connecting part 121 of the support 12. The threaded fastener 16 has a head 161, which is a rod head with a diameter larger than that of the screw rod of the threaded fastener 16. The head 161 is provided with a groove matched with a screwdriver. The support part 111 is connected with the connecting part 121 through the threaded fastener 16, and the head 161 of the threaded fastener 16 is located in the containing space 19 and abuts against the connecting part 121. The connecting part 121 is sunk into the avoiding groove 143, so as to make full use of the space of the avoiding groove 143, thereby reducing the thickness of the exposed wall part of the panel switch.

[0057] In one embodiment, the support 12 is a metal piece such as iron, and the connecting part 121 is annular and encloses an annular hole 123 which is a square hole. The connecting part 121 is provided with a first clamping part 124 extending along the direction close to the bottom wall of the containing groove 112. The base 13 is provided with a second clamping part 131, and the base 13 is connected with the support 12 through the clamping of the second clamping part 131 and the second clamping part 131, so as to realize the quick installation and disassembly and replacement of the support 12 and the base 13, and facilitate the production and transportation of the support 12 and the base 13.

[0058] Further, the first clamping part 124 is provided with a clamping groove, and the second clamping part 131 is provided with a clamping table. The clamping table and the clamping groove are clamped, so as to realize the quick installation and disassembly and replacement of the support 12 and the base 13. In other embodiments, the positions of the clamping groove and the clamping table can also be interchanged.

[0059] Optionally, the frame 14 and the support 12 of the application are different components respectively. Compared with the existing panel switch which integrates the frame 14 and the iron support 12, although the thickness can be reduced to a certain extent, the integration of the frame 14 and the support 12 is costly and not suitable for mass production. The frame 14 and the support 12 of the application are low in cost and easy to realize mass production. The separation design of the frame 14 and the support 12 makes the frame 14 simple in structure, easy to process and form, and easy to control the cost.

[0060] In one embodiment, the support portions 111 are arranged on the inner wall of the accommodating groove 112, and the support portions 111 are arranged in a plurality of and are spaced along the inner wall of the accommodating groove 112, each of the support portions 111 is provided with a first connecting hole 113, the connecting portion 121 is provided with a plurality of second connecting holes 125, the plurality of first connecting holes 113 and the plurality of second connecting holes 125 are one-to-one corresponding, and the threaded fastener 16 passes through the second connecting hole 125 and the first connecting hole 113 in sequence, thereby improving the connection degree of the bracket 12 and the cassette 11.

[0061] Optionally, the first connecting hole 113 is a threaded hole, and the threaded hole is threadedly connected with the screw rod of the threaded fastener 16. The second connecting hole 125 is a waist-shaped hole or a strip-shaped hole, so as to avoid the machining error to cause the difficulty in installing the bracket 12 and reduce the installation difficulty of the bracket 12. In other embodiments, the first connecting hole 113 can also be a light hole, and the support portion 111 is provided with a nut threadedly connected with the screw rod of the threaded fastener 16.

[0062] In one embodiment, the width of the frame 14 is greater than the width of the cassette 11, so that the lower end of the frame 14 can abut against the wall body 17 to realize positioning.

[0063] In addition, the existing part of the panel switch is a rear-mounted frame 14, although the thickness can be reduced, the rear-mounted frame 14 must be realized by bayonet fitting, and one of the frame 14 or the bracket 12 must be a plastic part, which has limitations for the material selection of the panel switch, and the strength of the panel switch is poor. The frame 14 and the bracket 12 of the present application can both be made of metal, and have high strength.

[0064] Further, the width of the mounting groove 141 gradually increases in the direction away from the support portion 111, and the width of the mounting groove 141 gradually increases from bottom to top, so as to facilitate the panel body 15 to be installed in the mounting groove 141 from top to bottom.
