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
