What is flush mounted socket?

A flush mounted socket is an electrical outlet that is installed flush with the surface of a wall or other surface, rather than being recessed or protruding. This type of socket is typically used in modern, minimalist design schemes where a sleek, streamlined appearance is desired. They are also used in applications where space is limited or where the socket needs to be protected from damage. They are easy to install, usually with a few screws, and are compatible with standard electrical plugs.
