[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Specifically, the lower circuit board 1 is moved downward, and the lower circuit board 1 drives the connecting block 2 to move downward and slide inside the groove 5 during the downward movement. The connecting block 2 will squeeze the card plate 8 during the downward movement and press the card plate 8 downward, thereby driving the inclined plate 9 and the pressure shaft 10 to lift upward, and also driving the slide plate 12 to move upward inside the limiting groove 6. The first spring 11 is also subjected to a tensile force. When the card plate 8 is squeezed, it will be stuck into the first card groove 3 due to the movement of the position of the connecting block 2, forming a fixing effect, thereby achieving the effect of facilitating installation.

[0026] Reference Figure 2 and Figure 4 A second card slot 13 is provided inside the mounting plate 4, a connecting frame 14 is fixedly connected to the outer wall of the lower circuit board 1, a card pin plate 15 is slidably connected inside the connecting frame 14, a shift block 16 is fixedly connected to the outer wall of the card pin plate 15, a second spring 17 is provided inside the connecting frame 14, a third spring 18 is provided inside the connecting frame 14, one end of the second spring 17 is fixedly connected to the outer wall of the card pin plate 15, and the other end of the second spring 17 is fixedly connected to the inside of the connecting frame 14;

[0027] Specifically, the lower circuit board 1 also drives the connecting frame 14 downward in the process of moving downward, thereby driving the locking plate 15 downward. When the locking plate 15 moves downward, it touches the mounting plate 4 and is squeezed by the mounting plate 4. The locking plate 15 moves to the right inside the connecting frame 14 and squeezes the second spring 17 and the third spring 18. When the locking plate 15 moves to the position of the second slot 13, it will be stuck in the second slot 13 due to the reset effect of the second spring 17 and the third spring 18, thereby achieving the effect of facilitating installation.

[0028] Reference Figure 1 , Figure 2 and Figure 4 One end of the third spring 18 is fixedly connected to the outer wall of the bayonet plate 15, and the other end of the third spring 18 is fixedly connected to the inside of the connection frame 14. The outer wall of the lower circuit board 1 is fixedly connected to a connector 19, the upper surface of the lower circuit board 1 is fixedly connected to an isolation plate 20, the upper surface of the isolation plate 20 is fixedly connected to an upper circuit board 21, the upper surface of the upper circuit board 21 is fixedly connected to a panel 22, and the upper surface of the panel 22 is fixedly connected to a button 23;

[0029] Specifically, the connector 19 can be connected to the device that needs to be controlled. An isolation plate 20 is provided on the upper surface of the lower circuit board 1 to isolate the lower circuit board 1 from the upper circuit board 21. After the connector 19 is connected, it can be controlled by the button 23 on the surface of the panel 22, so that the touch switch can start working. If it is necessary to disassemble the membrane switch, the latch plate 15 can be moved to the right by pulling the dial block 16 to the right, and the latch plate 15 slides out of the second slot 13. At the same time, the slide plate 12 is pressed downward. The slide plate 12 compresses the inclined plate 9 and the pressure shaft 10 downward, thereby lifting the card plate 8 and separating the card plate 8 from the connecting block 2 to achieve the disassembly effect.

[0030] Working principle: when it is necessary to install the membrane switch, the lower circuit board 1 is moved downward, driving the connecting block 2 to slide inside the groove 5. During the downward movement of the connecting block 2, the card plate 8 is squeezed, and the card plate 8 drives the inclined plate 9 and the pressure shaft 10 to lift up, and stretches the first spring 11, and also lifts the slide plate 12. When the connecting block 2 is moved downward, the card plate 8 will be stuck in the inside of the connecting block 2 and into the first card groove 3. At this time, the inclined plate 9 and the pressure shaft 10 are reset due to the rebound effect of the first spring 11, thereby achieving a fixed effect. In the process of moving downward, the lower circuit board 1 also drives the connecting frame 14 to move downward, and the connecting frame 14 drives the bayonet plate 15 to move downward. When the bayonet plate 15 moves downward, it is installed The mounting plate 4 is squeezed, thereby causing the latch plate 15 to move to the right and compress the second spring 17 and the third spring 18. When the latch plate 15 moves down to the position of the second slot 13, the second spring 17 and the third spring 18 are reset and fixed inside the second slot 13 due to the rebound effect of the second spring 17 and the third spring 18, thereby achieving the effect of auxiliary installation and fixation. If disassembly is required, press the slide plate 12 downward, and the slide plate 12 drives the inclined plate 9 and the pressure shaft 10 to squeeze the first spring 11 downward. At the same time, the card plate 8 is lifted up, thereby separating from the connecting block 2. At this time, the shift block 16 is shifted to the right again, and the shift block 16 drives the latch plate 15 to move to the right and slide out of the second slot 13, thereby achieving the effect of disassembly.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
