Title: Polar relay

Abstract: A balanced-armature type polar relay (10) capable of assuring, by its own structure, sufficient insulation distances, meeting the requirements of IEC60950, when mounted on an electric communication line connecting equipment, wherein a maximum distance between one movable contact and one fixed contact capable of being brought into contact with each other during the travel of an armature is set at 1 mm or more, and at least one of the abutting surfaces of the armature and the core polar surfaces of the electromagnet opposed to the abutting surfaces is formed as an inclined surface to reduce an angle of opposed surfaces at the time of mutual abutment to as little as possible, whereby the armature passes, during the travel thereof, a position where each of the pair of abutting surfaces faces the pair of corresponding core polar surfaces in parallel with each other.
