Abstract:
An electromagnetic relay including a contact switching unit formed by arranging at least two contact groups, in parallel with each other and perpendicular to the touch/separation direction of the contacts, each of the contact group includes a pair of contacts that can touch and separate; an electromagnet block that drives the contact switching unit to open and close the contacts; and an arc-extinguishing member comprising a connection member made from a magnetic material and formed by a connection of protrusions that respectively protrude from both sides of a middle part in the direction of the parallel arrangement of the contact groups and between the contact groups, and also comprising permanent magnets respectively disposed at least on the opposing positions of the protrusions located on both sides of the middle part.
