Abstract: An electromagnetic relay includes a base, an electromagnetic block disposed on an upper surface of the base, a movable iron piece that rotates based on excitation/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, is opposite to the movable contact and the base.

Abstract: Provided is an electromagnetic relay that is reduced in size and has great flexibility in designing. For this purpose, when a predetermined time has passed after generation of an arc at least either between a movable contact and a fixed contact or between a movable contact and a fixed contact, an arc generated between the movable contact and the fixed contact is extended by a magnetic field generation unit to be longer than an arc generated between the movable contact and the fixed contact.

Abstract: According to one or more embodiments, when a predetermined time has passed after generation of an arc at least either between a movable contact and a fixed contact or between a movable contact and a fixed contact, an arc generated between the movable contact and the fixed contact is extended by a magnetic field generation unit to be longer than an arc generated between the movable contact and the fixed contact.
