The electrical box, switch and plug-in mechanism is an revolutionary improved electrical box design, which the newly improved design of the electrical box facilitates prompt and safe installation of the newly designed electrical box, providing ease of installation to the user/installer. The newly improved electrical box, provides a more user/installer friendly environment, reducing installation time and reducing difficulty and/or installment of the electrical box, electrical switches and electrical plug-ins. Which in turn increases safety to the user/installer with replacement of electrical switches, electrical plug-ins and/or electrical boxes. Replacement of existing electrical boxes with the newly improved electrical box design allows the user/installer to easily and quickly replace electrical switch(s) and/or electrical plug-in(s) without touching/interfacing with electrical wiring within the improved electrical box plug-in type design. The newly improved electrical box contains electrical terminals for connection of electrical quick connect plug-in(s) allowing the installer to install/connect the electrical switch(s) or electrical plug-in(s) or other mechanical devices within the electrical box finalizing the electrical circuit connection. Installation of the electrical box plug-in type design increases safety to the user/installer when installing/connecting an electrical switch(s) or electrical plug-in(s), providing safety, quick and easy installation to the user/installer.

Improvements of the newly designed electrical box will not alter operation of current electrical switch(s) and/or electrical plug-in(s), the electrical box reduces exposure to electrical wiring within the electrical box increasing safety to the user/installer. Connectibility of the electrical wiring to the newly designed electrical box eliminates exposure to electrical wiring protecticting the user/installer when installing/connecting electrical switche(s) or electrical plug-in(s) to the electrical box.

Specific design features/improvements are incorporated into the electrical box are unlike the design of conventional electrical boxes. Design features and improvements include: male/female electrical wire receptacle terminals, labeled electrical wiring receptacle terminals, socket head receptacle fastening set screws and threaded electrical wiring

A housing for connecting to a plug connector part includes a plug-in opening, into which the plug connector part can be plugged in a plug-in direction; a wall which surrounds the plug-in opening; and a coding device which has at least one coding projection that protrudes inwards from the wall into the plug-in opening transversely to the plug-in direction and is designed to allow the plug connector part to be plugged into the plug-in opening in a specified angular position about the plug-in direction. The wall may have a first wall portion and a second wall portion which adjoins the first wall portion axially in the plug-in direction. The second wall portion may be offset outwards relative to the first wall portion in a direction transverse to the plug-in direction.
