Electromagnetic relay

An electromagnetic relay comprising:

• a base;
• an electromagnetic block disposed on an upper surface of the base;
• a movable iron piece that rotates based on excitation and non-excitation of the electromagnetic block;
• a movable contact piece that rotates integrally with the movable iron piece;
• a movable contact fixed to a free end of the movable contact piece;
• a fixed contact disposed so as to come into or out of contact with the movable contact in association with rotation of the movable contact piece;
• and
• a magnetic field generation unit disposed so as to attract an arc generated between the movable contact and the fixed contact in a direction that, as seen from the fixed contact or the movable contact, is opposite to a facing movable contact or a facing fixed contact, and in a direction opposite to the base, wherein
• the electromagnetic relay further comprises:
• a plurality of pairs of the movable contacts and the fixed contacts;
• a first magnetic field generation unit disposed so as to attract an arc generated between a first movable contact and a first fixed contact in a direction that, as seen from the first movable contact or the first fixed contact, is opposite to a facing first fixed contact or a facing first movable contact, and in a direction opposite to the base;
• and
• a second magnetic field generation unit disposed so as to attract an arc generated between a second movable contact and a second fixed contact and an arc generated between a third movable contact and a third fixed contact in an opposite direction to each other.
