The reed switch is an electrical switch operated by an applied magnetic field.It was invented in 1922 by a professor at Leningrad Electrotechnical University, and later evolved at Bell Telephone Laboratories in 1936 by Walter B. Ellwood into the reed relay. Advantages of this relay construction over existing remanent reed relays are the elimination of the magnetic shunt plate between the matched winding pair and the fact that the relay can either be operated or released by a single pulse.
