Abstract:
An electromagnetic relay including a contact switching unit having a pair of contacts. An electromagnet block drives the contact switching unit to open and close the contacts. An arc-extinguishing member includes a connection member and permanent magnets. The connection member is formed by connecting, via a middle part, opposing walls arranged in a direction perpendicular to the touch/separation direction of the contacts. Permanent magnets are disposed on opposing sections of the opposing walls.
