Abstract:
An electromagnetic relay has a movable iron core, an insulation holder integrated with an upper end portion of the movable iron core, a movable contact piece supported by the insulation holder, and a solenoid formed from a wound coil. The movable iron core is housed in an axial hole in the solenoid movably in the upward and downward directions. The movable iron core is adapted to be moved upwardly and downwardly based on magnetization and demagnetization of the solenoid for contacting and separating a movable contact point provided on the movable contact piece with and from a fixed contact point for opening and closing a contact point. A permanent magnet is embedded in a base portion of the insulation holder.
