Context

Country: North America
State/Province: Unknown
Period: late 19th century
Canada: A British 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 Coming into regular use around 1890, it rapidly superceded all other movements in Britain & ultimately went abroad to replace the established turn & two-button arrangements in America & Europe.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 (Ref.2).
