Claims

[Scope of Claim for Utility Model Registration] A ring-shaped permanent magnet, an iron core provided so as to bridge mutually opposing parts via a hollow part of the permanent magnet, and a ring-shaped permanent magnet arranged to interpose the iron core in conjunction with the permanent magnet. It has an armature having the same shape as the permanent magnet that is stacked on top of the other, and the permanent magnet has mutually opposing portions bridged by the iron core that are magnetized to have the same polarity,
The mutually opposing portions separated by the iron core are magnetized to the other polarity, and the armature is attached to the mutually opposing portions magnetized to the other polarity with the rotation center being a straight line connecting these opposing portions. A fulcrum for rotation is provided, and the armature is provided with means for connecting and separating the contact spring and the electrical contact portion when the armature rotates about the fulcrum, and the iron core is An electromagnetic relay comprising a winding that shares a part of the hollow space between the permanent magnet and the armature.
