A Canadian made switch of a type used in Canada. Part of a large & varied collection of over 7500 electrical items acquired & documented by Ontario Hydro in the 1960s. The collection was thought to be the largest & most comprehensive of its kind in Canada & was donated to the National Museum of Science & Technology in 1992. - Function
-
An electrical wiring device used to make or break a connection in an electrical circuit, specifically to disconnect or isolate the entire building from its source of supply. - Technical
-
Example of a knife switch. At first, all knife switches were mounted on wood or slate panels (later on porcelain) but although these bases were fairly efficient electrically, they were not really suitable for house service work. They were replaced in distributing panels by pull-out fuse-block switches but were still found in catalogues around 1950 (Ref. 1). This is an entrance switch, a device installed at or near the point where the service wires enter a building, to disconnect or isolate the entire building from its source of supply. - Area Notes
