ABSTRACT OF THE DISCLOSURE A polarized relay with an electromagnetic drive comprises an electromagnetic yoke composed of a core wound with a coil and a yoke body, and having one end portion of one magnetic polarity and a pair of bifurcated end portions of the other magnetic polarity opposite tothe one magnetic polarity. The bifurcated end portions are separated in opposition from each other. The one end portion of the yoke is disposed between the bifurcated end portions so as to cooperate to form a pair of working gaps. A movable block of a substantially C-like configuration incorporating a permanent magnet has two magnetic pole pieces which are disposed within the working gaps, respectively, Guide is provided for guiding the movable block in response to energization and deenergization of the coil so that the pole pieces are movable within the respective working gaps. A contact mechanism including movable contacts is mechanically coupled to the movable block to make or break circuit.
