Period
mid 20th century
Canada
A Canadian 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
The tumbler switch was one of the most characteristic British contributions to wiring installation practice. Coming into regular use around 1890, it rapidly superceded all other movements in Britain & ultimately went abroad to replace the established turn & two-button arrangements in America & Europe. The Kelvin switch of 1881 showed a radical departure from the influence of the gas tap. In Canada, the tumbler switch became popular only after 1930 (Ref. 1&2).
