Abstract:
1. An electromagnetic relay comprising: a contact switching unit having a contact group comprising a pair of contacts adapted to open and close; an electromagnet block which drives the contact switching unit to open and close the contacts; and an arc extinguishing member comprising a connection member, the connection member being formed by connecting, via a middle part, opposing walls arranged in a direction perpendicular to the open/close direction of the contacts, and permanent magnets being disposed on opposing sections of the opposing walls, wherein each permanent magnet is configured such that a polarity of opposing surfaces of said permanent magnets, and a direction in which an arc current, generated at a time of opening/closing of the pair of contacts, flows, are determined such that a force is generated on the arc current for displacing the arc current towards a middle part of the connection member.
