[0019] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0020] Embodiment 1:

[0021] like Figures 1 to 3 As shown, Figure 1 This is a schematic diagram of the overall structure of the luminous membrane switch. Figure 2 This is a bottom view of the illuminated membrane switch. Figure 3 1 is a schematic diagram of the installation position of the switch body 105. The utility model provides a light-emitting membrane switch: comprising a base 101 and an auxiliary device, wherein the base 101 is provided with a wire feed slot 102, wherein the wire feed slot 102 is L-shaped, and the auxiliary device comprises a threaded seat 103, a mounting platform 104, a switch body 105 and a protective cover 106. The above scheme can solve the problem that the existing light-emitting membrane switch is squeezed during transportation and its switch button is easily damaged. It can be understood that the above scheme can protect the switch body 105 during transportation to avoid damage caused by squeezing its switch button, which is conducive to subsequent stable use.

[0022] In this embodiment, a wire inlet groove 102 is provided on the base 101, and the wire inlet groove 102 is L-shaped. The wire inlet groove 102 is provided at the bottom of the base 101, and the wire inlet groove 102 is composed of a circular through hole and a rectangular groove, which together form an L-shaped wire passing structure, which is convenient for the base 101 to facilitate the passage of working cables when the switch body 105 is in use, and also facilitates the quick installation and fixation of the switch body 105.

[0023] Among them, the threaded seat 103 is detachably connected to the base 101 and is located on the base 101, the mounting platform 104 is detachably connected to the base 101 and is located in the mounting cavity formed by the base 101 and the threaded seat 103, the switch body 105 is detachably connected to the mounting platform 104 and is located on the top of the mounting platform 104, and the protective cover 106 is threadably connected to the threaded seat 103 and is located on the top of the threaded seat 103. The threaded seat 103 is installed on the base 101 by bolts, and the fixing bolts are installed from bottom to top and are countersunk. A connecting threaded cavity is set on the threaded seat 103 to facilitate the installation of the protective cover 106. The mounting platform 104 is fixed to the base 101 by bolts, and the bolts are countersunk. After installation, the mounting platform 104 will be located in the mounting cavity composed of the base 101 and the threaded seat 103, which is convenient for the installation of the switch body 105. The switch body 105 is installed on the mounting platform 104 by bolts. An operation button is set on the top of the switch body 105.

[0025] Then, the top end surface of the switch body 105 is flush with the top end surface of the threaded seat 103 after installation. After the switch body 105 is installed on the mounting platform 104 by bolts, the top end surface of the switch body 105 is flush with the top end surface of the threaded seat 103 after installation, which is convenient for operating the operation button on the switch body 105.

[0026] Finally, the protective cover 106 has a limiting plate 108, and the limiting plate 108 abuts against the top end surface of the threaded seat 103. The limiting plate 108 is arranged on the protective cover 106, which is conducive to the limiting abutment processing through the limiting plate 108 after the installation is completed.

[0027] When the utility model is used to solve the problem that the switch buttons of the existing luminous membrane switch are easily damaged due to being squeezed during transportation, first, the threaded seat 103 is installed on the base 101 by bolts, and then the mounting platform 104 is installed on the base 101 by bolts, and is located in the mounting cavity formed by the base 101 and the threaded seat 103. Further, the switch body 105 is installed on the mounting platform 104 by bolts. After installation, the top end surface of the switch body 105 is flush with the top end surface of the threaded seat 103 after installation, which is convenient for operating the operation button on the switch body 105. Finally, the protective cover 106 is directly installed. At this time, the switch body 105 can be protected during transportation to avoid damage caused by impact. When in use, the cable is inserted into the interior from the cable entry groove 102 and wired. Then, the base 101 is installed and fixed through the countersunk hole 107 to achieve the installation and fixation of the switch body 105. During transportation, it can be protected by the protective cover 106. When the switch body 105 needs to be operated, the protective cover 106 can be directly rotated to remove the operation, thereby solving the problem that the switch button of the existing luminous membrane switch is squeezed during transportation and is easily damaged.
