The metal threaded sleeve 10 can be connected with the metal round nut panel 1 or the installation and fastening metal nut 3 to fix the transfer switch body on the installation cabinet surface or screen wall.

[0026] like Figure 1 and 4 As shown, a transfer switch with a quickly changeable panel includes a metal round nut panel 1 and a transfer switch body 9. The installation and adjustment metal nut 2 is installed on the transfer switch body 9 through a threaded structure. The metal threaded sleeve 10 is installed on the head of the transfer switch body 9. The annular metal round nut panel 1 is sleeved on the transfer switch body 9 and is located on the outside of the installation and adjustment metal nut 2.

[0027] like Figure 2 and 5 As shown, a transfer switch with a quickly changeable panel includes an installation and adjustment metal nut 2, an installation and fastening metal nut 3, a plastic circular panel 4, a pressure plate screw 5, a circular nameplate 6, a transfer switch body 9 and a metal threaded sleeve 10. The installation and adjustment metal nut 2, the installation and fastening metal nut 3, the plastic circular panel 4 and the circular nameplate 6 are sequentially installed on the transfer switch body 9. The installation and fastening metal nut 3 and the plastic circular panel 4 are fixed together by the pressure plate screw 5. The metal threaded sleeve 10 is installed on the head of the transfer switch body 9.

[0028] like Figure 3 and 6As shown, a transfer switch with a quickly changeable panel includes: an installation and adjustment metal nut 2, an installation and fastening metal nut 3, a pressure plate screw 5, a plastic square panel 7, a square nameplate 8, a transfer switch body 9 and a metal threaded sleeve 10. The installation and adjustment metal nut 2, the installation and fastening metal nut 3, the plastic square panel 7 and the square nameplate 8 are sequentially installed on the transfer switch body 9. The installation and fastening metal nut 3 and the plastic square panel 7 are fixed together by the pressure plate screw 5. The metal threaded sleeve 10 is installed on the head of the transfer switch body 9.

[0029] like Figure 7 As shown, the mounting and fastening metal nut 3 is an annular structure having an annular boss. The outer side of the annular boss is an outer edge plane 32 , and a plurality of threaded holes 31 are opened on the outer edge plane 32 .

[0030] like Figure 8 As shown, the plastic circular panel 4 is an annular structure, on which an annular first edge platform 42 is provided. The first edge platform 42 is provided with two first through-hole arc grooves 41 .

[0031] like Figure 9 As shown, the plastic square panel 7 is a square structure with four arc transition corners. An annular second edge platform 72 is provided thereon, and two second through-hole arc grooves 71 are opened on the second edge platform 72 .

[0032] The use process of the present invention is as follows:

[0033] Unscrew the metal round nut panel 1 at the front end of the metal round nut panel transfer switch (switch without word plate identification) from the metal threaded sleeve 10 on the front of the transfer switch body 9, and then screw the installation and fastening metal nut 3 into the metal threaded sleeve 10 on the front of the transfer switch body 9 to fix it, and then press the plastic round panel 4 or the plastic square panel 7 onto the installation and fastening metal nut 3, and then pass the pressure plate screw 5 through the first through-hole arc groove 41 on both sides of the plastic round panel 4 and press it on the first edge platform 42, or the second through-hole arc groove 71 on both sides of the plastic square panel 7 and press it on the second edge platform 72 and screw it into the corresponding threaded hole 31 of the installation and fastening metal nut 3 to tighten it, so that the plastic round panel 4 or the plastic square panel 7 is in close contact with the outer aid plane 32 of the installation and fastening metal nut 3, and then snap the round word plate 6 or the square word plate 8 into the panel according to the shape of the panel, and the panel replacement is completed.

[0034] During the replacement process, when the metal round nut panel 1 and the installation and fastening metal nut 3 are replaced, the transfer switch body 9 can be taken out from the installation screen or cabinet, and when the plastic round panel 4 and the plastic square panel 7 are replaced, since the plastic round panel 4 and the plastic square panel 7 are installed on the installation and fastening metal nut 3, when the plastic round panel 4 and the plastic square panel 7 are replaced, the fastening force between the installation and fastening metal nut 3 and the transfer switch body 9 is not involved, and the transfer switch body 9 is stably fixed on the installation screen or cabinet.

[0035] The present invention can transform a switch without a signboard identification panel into a switch with a signboard identification panel by switching between a metal round nut panel and an installed and tightened metal nut. By leaving the installed and tightened metal nut unchanged and only replacing the plastic round panel or plastic square panel mounted thereon, the uses of different switch types can be quickly distinguished by the panel's appearance. During the conversion process between a metal round nut panel switch (without a signboard identification switch), a plastic round panel switch, and a plastic square panel switch, the switch body remains unchanged. The conversion between switch panels can be easily completed at the installation site, eliminating the need for factory adjustments and reducing installation effort.

[0036] By changing the installation of the metal round nut panel and the installation and tightening metal nuts, the conversion switch of the panel without a nameplate can be converted into a conversion switch with a nameplate panel, and the conversion switch with a nameplate panel can also be freely converted between a round panel and a square panel, so as to meet the needs of users to distinguish the function and use of the conversion switch through panels of different shapes on the screen or cabinet surface.
