    Abstract: An electromagnetic relay includes: a housing including a base and a case that opens downward and is provided on the base, the housing having an internal space surrounded by the base and the case; a main fixed contact; a main moving contact that comes into contact with and separates from the main fixed contact; an auxiliary fixed contact; an auxiliary moving contact that comes into contact with and separates from the auxiliary fixed contact; a coil provided in the housing such that a central axis extends in a vertical direction; an iron core disposed so as to be surrounded by the coil; a yoke disposed around the coil; an armature that is disposed to face an upper end of the iron core and swings in response to excitation/non-excitation of the coil; a movable part provided with the main moving contact and configured to move in response to swinging of the armature; and a partition wall that divides the internal space of the housing into a first space and a second space. The main fixed contact and the main moving contact are disposed in the first space, and the auxiliary fixed contact and the auxiliary moving contact are disposed in the second space.

    Abstract: To promptly extinguish an arc generated between contacts with a simple and inexpensive structure without negatively influencing the spring property of a movable contact piece. A contact switching mechanism includes a fixed contact piece with a fixed contact and a movable contact piece with a movable contact which faces the fixed contact in a contactable manner. At least either one of the contact pieces is provided with an extension which extends toward the contact of the remaining contact piece.

    Abstract: An electromagnetic relay includes an electromagnet part, an actuating part, a contact part and a base for holding the electromagnet part, the actuating part and the contact part. The contact part includes a pair of fixed plates having one end fixed to the base and the other end to which a fixed contact is attached, a pair of movable springs having one end fixed to the base and the other end to which a movable contact is attached, and a connecting portion extending between the movable springs and electrically connecting the movable contacts to each other. The actuating part is actuated so as to press only a part of the movable springs inside an area defined between longitudinal axes extending between one end and the other end of the movable springs through the movable contact, when the contact part closes.

    Abstract: An electromagnetic relay includes a coil, an armature that is electromagnetically attracted by the coil when current flows through the coil, two fixed contacts, a movable spring disposed to be movable to the fixed contacts, a conductive plate that is connected to the movable spring and including two movable contacts. The movable contacts are brought in contact with the fixed contacts respectively via the movable spring by the armature attracted by the coil. When the fixed contacts and the movable contacts are in contact, the fixed contacts are electrically connected to each other via the conductive plate. The movable spring is made of an insulating material.
