A Canadian made 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, specifically in a small motor. - Technical
-
An example of a rotary switch, turned in one direction to give on-off-on-off alternately. From 1880 to 1890 the great majority of switches were of the turn type. Out of the many possible movements for his switches, Edison chose that of turning, partly through its association with the gas tap (Ref. 3). - Area Notes
