摘要： In an armature of a hinge type relay having a movable contact elastically at one side, a rocking cardinal piece which is bendingly formed to the lower direction is provided at another side of the armature. A fulcrum piece which rockingly supports the rocking cardinal piece is provided at the lower portion of the upper bent portion of the yoke which supports the armature. The armature rocks due to the energization of the electromagnet, premitting the rocking cardinal piece to be a base point and the movable contact and the fixed contact separate or contact each other causing a relative wiping action. Foreign matter such as oxides, dusts and the like which generate at the contact points, and which cause a bad contact, are thereby removed, keeping the contacts continually clean.
