ABSTRACT:
An electromagnetic relay has a solenoid formed from a wound coil, a movable iron core that is reciprocated upwardly and downwardly in an axial hole of the solenoid, and a movable contact point that reciprocates together with the movable iron core. The movable contact point is contacted and separated with and from a fixed contact point for opening and closing a contact point. An arc generated at a time of opening and closing of the contact point is flowed, in a predetermined direction, by the magnetic field of at least a single permanent magnet placed at a side of the fixed contact point and the movable contact point that are contacted and separated with and from each other. Coil terminals are connected to leader lines of the coil, at least at a single side of the flow of the arc.
