The live wire is connected to socket L, socket L is connected to switch L with a short wire, the zero wire is connected to socket N, and the ground wire is connected to socket E (one vertical and three horizontal symbols).

Due to the nature of my job, I have always been interested in radio, so I have been engaged in the home appliance maintenance industry for more than 30 years and have been dealing with computer hardware for the past decade.

Looking at your diagram, is it already connected like this? There is a potential short circuit in the power line (moving the switch can cause a short circuit). If the switch is controlling this socket, the power live wire (red wire) should only be connected to the switch (which will be disconnected from the socket red wire), and then the line below the switch should be connected to the current live wire point of the socket.
