Can the single-opening and double-control be changed into a socket?

First of all, a friendly reminder: there are many dangers in electrical installation. Ask a professional electrician to operate in order to get the safety advice of the subjects.

Let's borrow a wiring diagram of "Baidu Picture" to illustrate:

As we can see in the picture, neither socket has a black zero line (N line); When the landlord needs to replace the switch with a socket, because there is no zero line, the function of 220V output cannot be realized.

The answer to the question is: If the lighting function is retained, then any switch cannot be changed into a socket without rewiring (threading).
