Claims (1)

[Scope of utility model registration request] An armature that is attracted to the attraction surface of the iron core by the excitation of a coil and is driven, a card that is placed parallel to the armature and whose longitudinal center part is driven into contact with the armature, and a card that is pushed toward the armature. A return spring that biases the card to return the card, conductive contact springs attached to both sides of the card, and a normally closed contact that is in contact with one of the contact springs and is placed closer to the return spring than the contact spring. and a normally open contact that contacts the other contact spring when the card is driven by the armature and is located on the opposite side of the contact spring from the return spring, and a normally open contact that is located between the normally closed contact and the normally open contact. 1. A structure of a relay having a common contact with which both contact springs alternately switch and make contact, characterized in that the point of action of the return spring to the card is provided on the normally closed contact side.
