Claim 0:
1. An electromagnetic relay comprising:
a first fixed terminal including a first fixed contact;
a second fixed terminal disposed apart from the first fixed terminal, the second fixed terminal including a second fixed contact;
a movable contact piece including a first movable contact facing the first fixed contact and a second movable contact facing the second fixed contact;
a drive device including a coil disposed in a first direction with respect to the movable contact piece, the first direction extending from the first movable contact toward the first fixed contact, the drive device configured to move the movable contact piece in a moving direction including the first direction and a second direction in which the first movable contact is separated from the first fixed contact;
a case including an accommodation space accommodating the first fixed contact, the second fixed contact, and the movable contact piece; and
a magnet disposed to overlap with the coil and the accommodation space in a third direction orthogonal to the moving direction and a longitudinal direction of the movable contact piece, the magnet configured to extend a first arc generated between the first fixed contact and the first movable contact and a second arc generated between the second fixed contact and the second movable contact in the longitudinal direction of the movable contact piece,
the case including a first arc extension space extending from the accommodation space in the first direction, the first arc extension space being at least partially disposed between the coil and the magnet.
