Period
early 20th century
Canada
An example of a socket of a type made & 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 support & connect to electricity a lamp or other electrical device.
Technical
An example of a Thomson-Houston socket of the early 1900s. From 1880 to 1889 other methods of supporting lamps appeared besides the Edison screw socket & receptacle, including the Thomson-Houston, the Westinghouse & the bayonet types. 1890 to 1899 was a period during which the details of wiring devices which had appeared in the previous decade were improved. Keys were added to lamp sockets & receptacles. Where the lamp switch was controlled by the wall or base switch, the socket could remain keyless; otherwise the light switch had to be incorporated within the socket utilizing as its switching mechanism the key, pull-chain or push-button (Ref.3). A simple arrangement which did not require the service of a mechanic to change a lamp was a necessity for commercial production of electric lamp sockets. In 1880 Edison introduced the screw cap which still bears his name. Holders with switches were Edison's original design. Much of the demand for these was left over from the days of lighting with gas and it took people some time to become accustomed to switching on the lights at the door. When portable lamps were introduced, the demand for switched sockets was reinforced (Ref. 2).
