- Rotary_system abstract "The Rotary Machine Switching System, or most commonly known as the Rotary System, was a type of automatic telephone exchange manufactured and used primarily in Europe from the 1910s. Formally named the No. 7-A Machine Switching System, it was developed in Belgium by International Western Electric, a subsidiary of American Telephone and Telegraph (AT&T), at the same time when AT&T's American engineering division, Western Electric, was developing the Panel switch in the United States.The Rotary and Panel systems were very different systems, but both used the same newly developed component technology, such as Western Electric's latest relays, and the principles of the Lorimer system of revertive pulsing and preselection. The Rotary switches were smaller than the Panel system, and served only 200 rather than 500 stations. The initial version was the model 7A. It was succeeded by 7A1 and 7A2 and a rural system had the designation 7D.".
