[0002] A membrane switch is an operating system that integrates button functions, indicator elements, and an instrument panel. It consists of four parts: panel, upper circuit, isolation layer, and lower circuit. When the membrane switch is pressed, the contacts of the upper circuit deform downward and make contact with the plates of the lower circuit to conduct electricity. When the finger is released, the contacts of the upper circuit bounce back, the circuit is broken, and the circuit triggers a signal. Membrane switches have a rigorous structure, beautiful appearance, good sealing, moisture resistance, and long service life. They are widely used in electronic communication, electronic measurement instruments, industrial control, medical equipment, automotive industry, smart toys, home appliances and other fields.

[0003] Most existing membrane switches use dedicated connectors, which means they can only be connected to specific devices. Because membrane switches do not have a universal interface, it is impossible to connect some special devices (such as computers, keyboards, etc.) to them.

[0004] Therefore, a membrane switch with a universal USB interface is proposed to address the above problems. Utility Model Content

[0024] In use, the device first connects the cable connector 7 to the cable interface 6, then connects the USB interface body 5 inside the socket 3 to the membrane circuit 9 via the connecting cable 8. The socket 3 is then assembled inside the through hole 2, and the membrane panel 1 and membrane back plate 13 are fixed together with adhesive strips 14. Finally, the bottom plate 4 of the socket 3 is encapsulated inside the membrane panel 1 and membrane back plate 13, ensuring the stability of the socket 3. This structure, through the USB interface body 5, enables the membrane switch to be connected to and used with different devices, improving the device's practicality. Example 2

[0025] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 4 As shown below, see details:

[0026] In a preferred embodiment, a data cable 11 is fixedly connected to one side of the thin-film circuit 9, and a connector 12 is fixedly connected to one end of the data cable 11. A fixing block 15 is fixedly connected to the bottom of the thin-film backplate 13. A rotating shaft 16 is rotatably connected inside the fixing block 15. Connecting blocks 17 are symmetrically fixedly sleeved on the outer side wall of the rotating shaft 16. A protective box 18 is fixedly connected to one side of the connecting block 17. The protective box 18 can be used to protect the data cable 11 and the connector 12. A fixing plate 19 is fixedly connected to one side of the protective box 18. A first threaded hole 20 is opened on the surface of the fixing plate 19, and a second threaded hole 22 is opened on the surface of the thin-film backplate 13. A fastening bolt 21 is provided on one side of the fixing plate 19. The fastening bolt 21 is movably disposed inside the first threaded hole 20 and the second threaded hole 22. In use, first pull the protective box 18 downward, and then, under the action of the rotating shaft 16 and the connecting block 17, the protective box 18 is opened. Next, the connecting connector 12 and the data cable 11 are wrapped and placed inside the protective box 18. Then, the protective box 18 is pulled upward to close the protective box 18 with the membrane back plate 13. Subsequently, the fastening bolt 21 is movably disposed inside the first threaded hole 20 and the second threaded hole 22, and the fastening bolt 21 is tightened to fix the protective box 18 with the membrane back plate 13, so as to prevent the data cable 11 and the connecting connector 12 from falling out of the protective box 18 if the protective box 18 is accidentally opened.

[0027] In a preferred embodiment, a membrane control button 23 is fixedly connected to the top of the membrane panel 1. An indicator light 25 is fixedly connected to the top of the membrane panel 1 and to one side of the membrane control button 23. The membrane circuit 9 is electrically connected to the membrane control button 23 and the indicator light 25. A label 24 is provided to one side of the indicator light 25. A display screen 10 is fixedly connected to the top of the membrane panel 1. An identification plate 26 is fixedly connected to the top of the membrane panel 1 and to one side of the socket 3. The identification plate 26 facilitates the identification of the membrane switch model by the staff. When in use, the device is operated by the membrane control button 23. At the same time, the membrane circuit 9 transmits the operation command to the indicator light 25 and the display screen 10, causing the corresponding indicator light 25 to light up, indicating that the controlled device is in a certain controlled state. The label 24 facilitates the staff to quickly identify the working status of the controlled device. At the same time, the display screen 10 displays the working animation for the staff to watch.

[0028] The working process of this utility model is as follows: First, the cable connector 7 is snapped into place with the cable interface 6. Then, the USB interface body 5 inside the socket 3 is electrically connected to the membrane circuit 9 through the connecting cable 8. Next, the socket 3 is assembled inside the through hole 2. Then, the membrane panel 1 and the membrane back plate 13 are fixed together with the adhesive strip 14. Finally, the bottom plate 4 of the socket 3 is encapsulated inside the membrane panel 1 and the membrane back plate 13. The bottom plate 4 ensures the stability of the socket 3. This structure enables the membrane switch to be connected to and used with different devices through the USB interface body 5, thus improving the practicality of the device.

[0029] When connection to a specific device via data cable 11 and connector 12 is not required, first pull the protective box 18 downwards. Then, under the action of the pivot 16 and connecting block 17, the protective box 18 opens. Next, wrap the connector 12 and data cable 11 around and place them inside the protective box 18. Then, pull the protective box 18 upwards to close it with the membrane backplate 13. Then, move the fastening bolt 21 through the first threaded hole 20 and the second threaded hole 22, and simultaneously tighten the fastening bolt 21 to fix the protective box 18 to the membrane backplate 13, preventing the protective box 18 from being damaged. 8. Accidental opening causes the data cable 11 and connector 12 to fall out of the protective box 18. After the controlled device is connected to the membrane switch via the USB interface body 5, the device is operated through the membrane control button 23. At the same time, the membrane circuit 9 transmits the operation command to the indicator light 25, causing the corresponding indicator light 25 to light up, indicating that the controlled device is in a certain controlled state. The label 24 makes it easy for staff to quickly identify the working status of the controlled device. At the same time, the display screen 10 displays the working animation for staff to watch. The above is the working principle of a membrane switch with a universal USB interface.
