A switch of a type 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 make or break a connection in an electrical circuit. - Technical
-
The first patent for a push-button switch was granted to Ediswan in 1895. The single push-button switch had the disadvantage of not indicating if the switch is open or closed & has seldom been used. The two button arrangement, however, was free from this defect & enjoyed great popularity in America until the late 1920s (Ref. 2). - Area Notes
