Period

Canada

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
Example of switch of toggle type, in which dolly & contacts rigidly connected with springs provided definite on & off. Originating in England, the tumbler switch came into regular use about 1891 & rapidly superceded all other movements, replacing the established turn & turn button arrangement. The Kelvin switch of 1881 showed a radical departure from the influence of the gas tap (Ref. 2). Although in Canada tumbler switches Beginning around 1905, the design of tumbler switches became simpler & thinner. In Canada, the flush type soon became the favourite over the surface type. The latter was probably still available for older houses in which flush type switches could not be used. Still, until the late 1920s, the turn type switch (snap) & push button switch were the type most often seen in catalogues (Ref.1).
