Abstract
An electromagnetic relay includes a base, a contact block, an electromagnet block, a permanent magnet, and a rigid member. The base is insulating. The contact block is placed on the base. The electromagnet block is placed on the base at a space from the contact block. The permanent magnet generates a magnetic field in the contact block. The rigid member is made of a magnetic material having a higher rigidity than the base, is incorporated in the base, and suppresses a magnetic flux leakage of the permanent magnet.
Claims6
