Abstract

A polarized reed relay comprises a bobbin with a coil wound thereon, two ferromagnetic contact reeds extending through an interior passage of the bobbin, a permanent magnet, and two pairs of pole shoes. Each contact reed is fixed at one end and has its other, free end cooperating with fixed contact portions formed by a pair of pole shoes. A relay is thus provided in which two double-throw contact systems electrically insulated from each other may be operated absolutely synchronously.
