Abstract
An electromagnetic relay includes an electromagnet device, an armature and a fixed terminal. By coil current through a coil, the electromagnet device generates first magnetic flux that forces the armature and the electromagnet device together or apart in a first end in a first direction of the armature. The armature is connected with a movable contact at a second end of the first direction and forces the movable contact and a fixed contact together or apart according to coil current. The fixed terminal is electrically connected with the fixed contact, and provided around the armature so as to cross the armature as seen from a second direction perpendicular to the first direction with the armature closing the fixed and movable contacts. Electric current through the fixed terminal generates a second magnetic flux in the armature, a direction of which is opposite to that of the first magnetic flux.
