The base supports the fixed terminal. The fixed contact is connected to the fixed terminal. The movable contact faces the fixed contact. The movable contact is connected to the movable contact piece. The movable terminal is fixed to the base. The movable terminal is connected to the movable contact piece. The card pushes the movable contact piece to move the movable contact. The contact protrusion is provided on the movable contact piece. The contact protrusion contacts the card to allow the card to press the movable contact piece.

An electromagnetic device includes a spool including a cylindrical body portion in which a through hole extending to a first direction is provided, a coil wound around the body portion, an iron core disposed in a through hole of the body portion, a yoke including a first member and a second member, the first member being connected to the iron core and the second member extending from the first member along an outer peripheral surface of the coil, and a movable iron piece, which has a plate shape, including a bent portion in a middle thereof. The yoke includes at least one positioning projection provided in a middle of the free end in the second direction. The movable iron piece includes a positioning recessed portion that accommodates and positions the positioning projection, the positioning recessed portion being provided in a middle between the pair of rotation supporting points.

A relay includes a fixed terminal, a fixed contact connected to the fixed terminal, a movable contact piece facing the fixed terminal, a movable contact, a drive unit including a coil and an armature operated by electromagnetic force generated from the coil, a card, and a wall disposed between the armature and the card. The movable contact is connected to the movable contact piece and faces the fixed contact. The card is disposed between the drive unit and the movable contact piece, and transmits an operation of the armature to the movable contact piece. The card includes a card body, a contact part, and a protrusion. The card body is disposed between the wall and a movable contact piece. The contact part extends from the card body toward the armature. The protrusion protrudes from the card body toward the wall and is disposed on a side of the contact part.

An electromagnetic relay includes a base having a receiving space, an electromagnetic unit disposed outside of the receiving space, a magnetically attractive member magnetically attractable by the electromagnet unit, a first stationary contact disposed in the receiving space, a second stationary contact, a movable terminal member and a movable contact. When the electromagnetic unit is energized, the movable terminal member is pushed by the magnetically attractive member and the movable contact contacts one of the first and second stationary contacts. When the electromagnetic unit is de-energized, the movable contact contacts the other one of the first and second stationary contacts.
