Context

Country: North America
State/Province: Unknown
Period: circa 1914+
Canada: An American made switch of a type used in Canadian households. 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 in domestic lighting.
Technical: An example of a rotary switch. Edison was one of the very first to give serious attention to the question of the branch switch. Out of the many possible movements, he chose that of turning, partly through its association with the gas tap. He thought that it would be a good selling point to allow his customers to turn electricity on or off in the same manner as they were accustomed to dealing with gas. From 1880 to 1890 the great majority of switches were of the turn type (Ref. 3). First they were made of wood, with no definite on or off positions. Later switch bases were made of marble or slate, then porcelain with definite on-off positions. Another improvement was quick-make-and-break mechanisms. Rotary switches remained popular in Canada until the late 1920s, but gradually were used more in stoves & other appliances than lighting. By 1921 they no longer appeared in Canadian catalogues (Ref. 1)
