Magnetization and Pull Characteristics of Mating Magnetic Reeds
01 March 1961
A scaled rood relay comprises one or more sealed contacts assembled with a coil and shielding and supporting members. The distinctive feature is the construction of a sealed contact. 1. In its simplest form, as shown in Fig. 1, it consists of a glass envelope in which are sealed a pair of magnetic reeds, which serve as contacting members, actuated by the magnetic field induced in them by the coil current. In another form," there is only one moving reed, the other magnetic member being short and nearly rigid. This construction, using two of these short members to provide both back and front contacts, has been 524 T H E B E L L SYSTEM T E C H N I C A L J O U R N A L , MARCH 19G1 cl-ยป| p V "1 La-J Fig. 1 -- Dimensions of mating magnetic reeds.
