[0011] As a further description of the above technical solution:

[0012] Several through slots are provided on both sides of the mounting frame.

[0013] As a further description of the above technical solution:

[0014] The touch-sensitive switch body is equipped with an indicator light. The bottom of the upper half of the split-type dustproof plate is provided with a fourth groove. A push-button switch is fixedly installed inside the fourth groove. The output end of the push-button switch is electrically connected to the input end of the indicator light. The top of the lower half of the split-type dustproof plate is fixedly connected with a protrusion that mates with the fourth groove.

[0015] As a further description of the above technical solution:

[0019] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are as follows: When the touch area needs to be touched, the user operates with one hand, using the thumb and middle finger to contact the two sets of second grooves respectively to push the dustproof plate open, exposing the touch area. The user then touches the touch area with the index finger to complete the switch operation. After the touch is completed, to avoid dust on the surface of the touch area, the user should immediately release their fingers. Under the elastic action of the compression spring, the slider drives the dustproof plate to move towards each other, and the protrusion enters the fourth groove to squeeze the push-button switch, turning on the indicator light to indicate to the user that the dustproof plate is completely closed.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-4 This utility model provides a technical solution: a capacitive contact switch structure, including a touch-sensitive switch body 1, a touch area 9 in the middle of the touch-sensitive switch body 1, and first grooves 101 on both sides of the touch area 9. A mounting frame 4 is detachably connected to the first groove 101, and an iron fixing frame 8 is fixedly connected to the first groove 101. Several third grooves 402 are provided on the outer side of the mounting frame 4. A trapezoidal magnet 10 connected to the fixing frame 8 is connected to the third groove 402. A rubber pad 12 is adhered to the third groove 402. During the process of inserting the mounting frame 4 into the fixing frame 8, the magnet 10 squeezes the rubber pad 12 until the mounting frame 4 is fully inserted into the fixing frame 8. The rubber pad 12 rebounds, so that the magnet 10 connects with the iron fixing frame 8 and is adhered to the rubber pad 12. Several through grooves 401 are provided on both sides of the mounting frame 4. The mounting frame 4 is fixed in the grooves 101 under the connection of the magnet 10 and the iron fixing frame 8. The user can easily disassemble and install the mounting frame 4 through the through grooves 401.

[0028] Specifically, such as Figure 1 and Figure 2As shown, a stepped rod 5 is fixedly connected inside the mounting frame 4. Two sets of compression springs 6 and sliders 7 are sleeved on the stepped rod 5. One end of the compression spring 6 is fixed, and the other end is fixedly connected to the slider 7. A split dustproof plate 3 is fixedly connected between the sliders 7. The dustproof plate 3 covers the touch area 9. The upper and lower parts of the split dustproof plate 3 have a second groove 301 near the seam, which facilitates one-handed operation to open the dustproof plate 3 and expose the touch area 9 for switch operation. A felt layer 11 that contacts the surface of the touch-sensitive switch body 1 is glued to the bottom edge of the dustproof plate 3. To prevent dust from entering the touch area 9, an indicator light 2 is provided on the touch-sensitive switch body 1. The bottom of the upper half of the split-type dustproof plate 3 has a fourth groove, and a push-button switch 13 is fixedly installed inside the fourth groove. The output end of the push-button switch 13 is electrically connected to the input end of the indicator light 2. The top of the lower half of the split-type dustproof plate 3 is fixedly connected to a protrusion 14 that cooperates with the fourth groove. When the dustproof plate 3 is squeezed and closed by the elastic action of the compression spring 6, the protrusion 14 squeezes the push-button switch 13, turns on the indicator light 2, and indicates to the user that the dustproof plate 3 is completely closed.

[0029] Working principle: When in use, when it is necessary to touch the touch area 9, the user operates with one hand, using the thumb and middle finger to contact the two sets of second grooves 301 respectively, pushing the dust cover 3 to open and exposing the touch area 9. The user then touches the touch area 9 with the index finger to complete the switch operation. After the touch is completed, to avoid dust on the surface of the touch area 9, the user should immediately release their fingers. Under the elastic action of the compression spring 6, the slider 7 drives the dust cover 3 to move towards each other, and the protrusion 14 enters the fourth groove to squeeze the push-button switch 13, turning on the indicator light 2 to indicate to the user that the dust cover 3 is completely closed.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
