A first end portion includes a first contact. A second end portion includes a second contact. At least a first end portion, out of the first end portion and a second end portion, is curved to be folded back from a tip in one direction of the first end portion. The first contact is located in a folded-back part of the first end portion and faces the second contact.

A first fixed terminal includes a first support portion and a first extending portion. The first support portion is located in a closing direction with respect to a movable contact piece. The first support portion supports a first fixed contact. The first support portion extends from the first fixed contact in a first lateral direction. The first lateral direction is one direction in a longitudinal direction of the movable contact piece. The first extending portion is connected to the first support portion. The first extending portion extends in the closing direction from the first support portion. The first extending portion is disposed apart from the movable contact piece in the first lateral direction.

Provided is an electromagnetic relay including a case, a first fixed contact terminal including a first fixed contact, a second fixed contact terminal including a second fixed contact, and a movable touch piece including, on one surface of the movable touch piece, a first movable contact and a second movable contact configured to come into and out of contact in a contact-making and breaking direction. The first fixed contact terminal includes a facing portion disposed facing the other surface of the movable touch piece with a gap provided between the facing portion and the movable touch piece, and at least part of the facing portion lies over the movable touch piece in plan view in the contact-making and breaking direction.

An electromagnetic relay has a contact device and an electromagnet device. An electromagnetic relay has stators which are a pair of rod-like members, and a mover. The mover may face the side of the stator. A housing supports the stator and accommodates the mover. A yoke is fixed to the housing so as to face the movable facing surface and contains a soft magnetic material.

A magnetically actuated MEMS switch 100 includes a first magnetic core portion 120, a first signal line 15, a first contact point 16, a second magnetic core portion 220, a second signal line 25, a second contact point 26, and a first coil portion 111 and a second coil portion 211 serving as a magnetic field applying portion that causes a current to flow in conductor coil to apply a magnetic field to the first magnetic core portion 120 and the second magnetic core portion 220. The first contact point 16 is displaced depending on the presence or absence of a magnetic field applied by the magnetic field applying portion. Connection and disconnection between the first contact point 16 and the second contact point 26 are switched in response to displacement of the first contact point 16.

The present invention disclosure relates to a direct current relay and, more particularly, to a direct current relay including a mover assembly having improved support force with respect to a movable contactor. The direct current relay according to an embodiment of the present invention disclosure comprises a pair of fixed contactors and a movable contactor which is moved up and down by an actuator to come into contact with or be separated from the pair of fixed contactors, comprises a mover support disposed below the movable contactor and connected to the actuator by a shaft; a mover holder disposed above the movable contactor and fixed to the mover support; a contact pressure spring disposed between the movable contactor and the mover support to provide a contact pressure to the movable contactor; and a supporting pin installed to extend through the movable contactor and the mover holder.

The invention relates to a low-voltage switching device comprising an electromagnetic drive having a coil (1), a fixedly positioned yoke (2), and an armature (3), which is movable relative to the yoke (2), and also comprising a contact system consisting of a fixedly positioned switch piece carrier (4) having a movable switch piece carrier (5) arranged opposite thereto, wherein the movable switch piece carrier (5) is acted upon by a contact load spring (7). The invention is characterized in that a first means for electromagnetic contact load support is positioned on the fixedly positioned switch piece carrier (4).

A control system is designed to control an interrupter. The interrupter is started by a startup current to interrupt a main electric circuit. The startup current flows through an auxiliary electric circuit and has a current valve equal to or greater than a predetermined value. The control system includes a driving unit and a driven unit. The driving unit includes an intermediate electrical path to be connected to the main electric circuit. The driven unit is to be connected to the auxiliary electric circuit. When an abnormal current having a current value equal to or greater than a prescribed value flows through the intermediate electrical path, the driving unit uses, as a drive source for driving the driven unit, the abnormal current flowing through the intermediate electrical path. The driven unit supplies the auxiliary electric circuit with the startup current by being driven by the driving unit.
