摘要： The invention relates to hermetically sealed contacts, electromagnetic devices using such contacts, as well as method and means for controlling such electromagnetic devices.A hermetically sealed contact (reed switch), comprising a capsule enclosing at least two peripheral elastically mounted magnetically controlled cores permanently anchored in the ends of the capsule and a central elastically mounted magnetically controlled core at least partially overlapping the peripheral ones and secured in a supporting member arranged in the capsule intermediate of the inner ends of the peripheral cores, is, according to the invention, characterized by that the supporting member is made elastic and the elasticity thereof is less than the transverse elasticity of the central magnetically controlled core, the latter being secured symmetrically with respect to the elastic supporting member so that when a magnetic flux is applied to the cores, it gives rise to an electromagnetic force of attraction between the magnetically controlled cores, and the central core comes in or out of contact with one of the peripheral cores.
