Claims

[Claims for Utility Model Registration] (1) A core, a coil wound around the core, a substantially L-shaped yoke, an armature, fixed to the armature, having a movable contact at one end and a predetermined end at the other end. In an electromagnetic relay including a movable contact spring bent at an angle and fixed to the yoke, and a fixed contact with which the movable contact contacts and separates, a permanent magnet is provided on the outer periphery of the attraction surface of the core to the armature. A low-noise electromagnetic relay characterized by the arrangement of (2) A core, a coil wound around the core, a substantially L-shaped yoke, an armature, and the yoke is fixed to the armature and has a movable contact at one end and is bent at a predetermined angle at the other end. In an electromagnetic relay including a movable contact spring fixed to a fixed contact spring, and a fixed contact with which the movable contact contacts and separates, a permanent magnet is positioned on the outer periphery of the core when the armature is attracted to the core. A low-noise electromagnetic relay that is fixed to the underside of the armature.
