Abstract: A switch cover guard for guarding at least one electrical device in an electrical plate against access, use and/or damage has a security chamber surrounded by first, second, top and bottom guard walls. The security chamber is open to the rear to allow electrical switches/outlets to be accessed from within the chamber once the rear of the switch cover guard is attached onto the electrical plate. A front security plate can be slid between an open position, which allows access to the switch/outlet, and a closed position. When closed, the security chamber is sealed and the switch/outlet is no longer accessible. An adhesive attachment layer can secure the guard directly to the switch/outlet plate without requiring the plate to be opened. The front security plate can have a transparent or translucent front panel to allow light to pass through while the switch cover guard is closed.
