An electromagnetic relay has an iron core having legs at both ends and a coil wound therearound to form an electromagnet, a movable iron piece that pivotally supports a pivoting shaft along one leg of the iron core and causes a tip of a pivoting arm extended from a side edge of the pivoting shaft toward the other leg of the iron core to face the other leg of the iron core in a contactable and separable manner, and a card whose side facing the movable iron piece is in contact with the pivoting arm of the movable iron piece. The movable iron piece that pivots based on the excitation and degaussing of the electromagnet presses the card to drive a contact mechanism.

Electromagnetic relay

An electromagnetic relay includes an electromagnetic part, a movable iron piece, a contact driving part, a contact which is opened and closed by driving the contact driving part with a card disposed between the movable iron piece and the contact driving part. Particularly, the card is disposed between the insulating wall and the contact driving part, a driving projection projected onto an inward surface side opposed to the insulating wall of the card is inserted in and projected from a manipulation hole made in the insulating wall, and the driving projection of the card is pressed by the movable iron piece that is operated based on excitation and demagnetization of the electromagnetic part.
