An electrical receptacle includes a switch having an open state and a closed state; an electrical socket that receives an electrical plug; an electrical interface that directly couples to electrical wires and conductively carries current to the switch; a user interface having an input device that receives user commands, and an output device that sends user signals; and a timer that, upon user command, causes the switch to close. When the switch is in the closed state, current conductively reach the electrical socket. When in the open state, current does not conductively reach the electrical socket.
