Multi-function sockets mainly refer to three-hole sockets. The plug type specified by our national standard is flat, with two poles and two poles with grounding (commonly known as “3-hole”) plugs. Cylindrical plugs are non-standard products that have been eliminated. But I don’t know why the two holes have round heads, while the three holes do have two flat and round types? According to the specification, I personally think that they should be flat plugs. Multi-function sockets are generally used for computers, and general electrical appliances are rarely used! Multi-function sockets are not safe for children due to their relatively large holes, so the door must be protected.
