[0021] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0022] like Figure 1-5 As shown, a waterproof electrical switch includes a switch box base 1, a protective component 2, a protective shell 21, a control switch button 14, an airbag 22, and an internal slot 23. The protective component 2 is provided on the top of the switch box base 1, and the protective component 2 covers the entire top of the switch box base 1.

[0023] The protective component 2 includes a protective shell 21 that is partially inserted into the switch box base 1. The protective shell 21 has a push-button feature, wherein the protective shell 21 is as follows: Figure 2 and Figure 5 As shown, a rectangular frame, made of transparent rigid material, is used to connect the protective shell 21 and the switch box base 1. The bottom of the protective shell 21 has an internal groove 23, which is used to insert the control switch button 14 inside the switch box base 1 and to enclose the control switch button 14. Both ends of the internal groove 23 have air bladders 22. When the pressing part is pressed, the air bladders 22 will have an air release structure, so that the control switch button 14 can be pressed without separating the protective shell 21 and the switch box base 1. The design of the control switch button 14 also prevents water and dust from entering the protective shell 21 when it is not in use, thus achieving waterproof and dustproof functions for the inside of the switch box base 1. The air bladder 22 penetrates the protective shell 21 and is connected to the outside of the protective shell 21 for venting.

[0024] The effect achieved by the entire embodiment is that, through the connection between the protective shell 21 and the switch box base 1, when the control switch button 14 needs to be operated, the pressing part is pressed. At this time, the airbag 22 will release air when the pressing part is pressed, so that the control switch button 14 can be pressed without separating the protective shell 21 and the switch box base 1. Furthermore, the design of the control switch button 14 ensures that the protective shell 21 will not have water or dust entering it when it is not in use, thus achieving waterproof and dustproof functions for the switch box base 1. Example 2

[0025] like Figure 1-5As shown, a waterproof electrical switch includes a push-button part comprising a cavity 212 formed within a protective housing 21. The cavity 212 can be filled with antifreeze during use, ensuring that the antifreeze does not solidify even with large temperature variations. The amount of antifreeze added is appropriate; the cavity 212 should not be overfilled. After filling with antifreeze, the push-button part should still allow the control switch button 14 to be pressed. A first transparent rubber membrane 211, made of soft rubber, is connected to the upper part of the cavity 212. A second transparent rubber membrane 213, also made of soft rubber, is connected to the lower part of the cavity 212, facilitating the pressing of the control switch button 14. Pressing the control switch button 14 does not require opening the mounting plate 24, and air can be released at the airbag 22 position. Furthermore, the antifreeze reduces the occurrence of moisture in the first and second transparent rubber membranes 211 and 213.

[0026] The first transparent rubber film 211 and the second transparent rubber film 213 are both made of transparent soft rubber. The first transparent rubber film 211 and the second transparent rubber film 213 cover the protective shell 21 to protect the entire protective shell 21 and the control switch button 14.

[0027] The overall effect of the second embodiment is that the cavity 212 can be filled with antifreeze during use. It can ensure that the cavity 212 will not solidify when the antifreeze temperature changes greatly. The amount of liquid filled is appropriate, and the cavity 212 should not be overfilled. After filling with antifreeze, it should be ensured that the control switch button 14 can still be pressed. When pressing the control switch button 14, it is not necessary to open the mounting plate 24. At the same time, air can be released at the airbag 22 position. When the first transparent rubber film 211 is pressed, the force is transmitted to the surface of the control switch button 14 under the action of the first transparent rubber film 211, the cavity 212 and the second transparent rubber film 213, controlling the opening and closing state of the circuit. Example 3

[0028] like Figure 1-5 As shown, a waterproof electrical switch has a base 1 with fixing plates 12 connected to both ends. Circuit wires are folded inside the fixing plates 12 to control the operating status of the switch button 14.

[0029] The end of the fixing plate 12 away from the switch box base 1 is connected to the connecting wire 11. One end of the circuit wire passes through the connecting wire 11 and connects to the external wire, which is used to connect the control switch button 14 to the external circuit.

[0030] A control switch button 14 is connected to the top of the switch box base 1. The control switch button 14 is connected to the other end of the circuit wire and is used to control the opening and closing state of the circuit.

[0031] The control switch button 14 is equipped with two guide signs 15, one for opening and one for closing, for the convenience of the operator. The control switch button 14 has a plug-in groove 13 for the protective component 2 to be inserted. The plug-in groove 13 has a snap-fit ​​groove for the mounting plate 24 to be fastened. The protective shell 21 is made of rigid material. The mounting plate 24 is connected to the surface of the protective shell 21 away from the airbag 22. The mounting plate 24 and the plug-in groove 13 are connected by a snap-fit. The plug-in groove 13 and the mounting plate 24 can also be connected by threaded grooves and external bolts. The connection method is not unique. The purpose is simply to connect the protective shell 21 and the switch box base 1 into a detachable structure.

[0032] The effect achieved by the entire embodiment 3 is that the control switch button 14 and the external circuit to be controlled are connected by the fixing plate 12 and the connecting wire 11, and then the mounting plate 24 and the plug slot 13 are connected. The mounting plate 24 and the plug slot 13 are connected by a snap-fit ​​connection. The plug slot 13 and the mounting plate 24 can also be connected by opening a threaded groove and external bolts. The connection method is not unique. The purpose is simply to connect the protective shell 21 and the switch box base 1 into a detachable structure.

[0033] Working principle: When using this electrical switch, it is connected to the external wires through the connecting wire 11. First, the control switch button 14 is connected to the external circuit to be controlled through the fixing plate 12 and the connecting wire 11. Then, the mounting plate 24 and the plug slot 13 are connected. The mounting plate 24 and the plug slot 13 are connected by a snap-fit. The plug slot 13 and the mounting plate 24 can also be connected by opening a threaded groove and external bolts. The connection method is not unique. The purpose is simply to connect the protective shell 21 and the switch box base 1 into a detachable structure.

[0034] Secondly, the protective shell 21 is connected to the switch box base 1. When the control switch button 14 needs to be operated, the pressing part is pressed. At this time, the air bag 22 will release air when the pressing part is pressed, so that the control switch button 14 can be pressed without separating the protective shell 21 and the switch box base 1. The design of the control switch button 14 also prevents water and dust from entering the protective shell 21 when it is not in use, thus achieving waterproof and dustproof functions for the switch box base 1.

[0035] Finally, the cavity 212 can be filled with antifreeze during use. This ensures that the antifreeze will not solidify in the cavity 212 when the temperature changes greatly. The amount of antifreeze should be appropriate, and the cavity 212 should not be overfilled. After filling with antifreeze, it should be ensured that the control switch button 14 can still be pressed. When pressing the control switch button 14, it is not necessary to open the mounting plate 24. At the same time, air can be released at the airbag 22 position. When the first transparent rubber membrane 211 is pressed, the first transparent rubber membrane 211, under the action of the cavity 212 and the second transparent rubber membrane 213, transmits force to the surface of the control switch button 14, controlling the opening and closing state of the circuit, and finally completing the operation of the electrical switch.
