An example of a switch cover of a type used in Canada. Part of a large and varied collection of over 7500 electrical items acquired and documented by Ontario Hydro in the1960s. The collection was thought to be the largest and most comprehensive of its kind in Canada and was donated to the National Museum of Science and Technology in 1992. - Function
-
A cover for a wall switch box, exposed wiring and the opening around a switch - Technical
-
Switches & receptacles can not be mounted in walls leaving untidy openings around them, nor can the terminals be left exposed for that would not be safe. Therefore they are covered with wall plates or face plates after installation (Ref. 2)./ Bakelite is phenol formaldehyde plastic patented in1907. It was most used from the 1920s to the 1950s, especially during the 1920s and 1930s. The electrical industry was the first to take an interest in bakelite since it met the demand for an insulating material. Plugs, sockets, switches, insulators and accessories were often made of brown, black or simulated wood grain bakelite until other colours were introduced in the 1920s (Ref. 3). - Area Notes
