[0020] The specific implementation modes of the present invention are described below in conjunction with the accompanying drawings and embodiments. However, the following embodiments are only used to illustrate the present invention in detail and do not limit the scope of the present invention in any way.

[0021] Example 1: A high protection electronic switch, see Figures 1 to 3 , including a shell and a button switch 3, a circuit board 4 is arranged inside the shell. The shell includes an upper shell 1 and a lower shell 2, and two through holes are arranged in the middle of the top plate of the upper shell 1 for installing the button switch 3. The button switch 3 is cylindrical and is plugged into the shell through the through holes. The upper shell 1 has an upper accommodating chamber for accommodating the button switch 3, and the lower shell 2 has a lower accommodating chamber for accommodating the circuit board 4, and the circuit board 4 is fixed to the bottom surface of the lower shell 2. The upper and lower accommodating chambers are surrounded to form a closed space, and a sealing ring 23 made of rubber material is arranged between the two.
