Abstract
An electromagnetic relay includes an electromagnet unit, an armature supported so as to be pivotable relative to a yoke by a hinge spring, a contact including a first contact and a second contact, which can switch, in accordance with pivoting of the armature, between a closed contact state and an open contact state, an elastic member which elastically deforms in accordance with pivoting of the armature, and applies a contact force between the first contact and the second contact in the closed contact state, and a magnet which generates an attractive force for retaining the armature in an open contact position corresponding to the open contact state, wherein the armature is retained in the open contact position by a resultant force of a restoring force applied to the armature by the hinge springe, and the attractive force of the magnet.
