An electromagnetic relay includes a fixed contact; a movable contact movable between a first position at which the movable contact contacts the fixed contact to form a closed state, and a second position at which the movable contact does not contact the fixed contact to form a opened state; an electromagnet that includes a coil, a magnetic core, and a yoke coupled to the magnetic core, and generates magnetic field; and an actuator that includes a pair of armatures, and a permanent magnet sandwiched by the pair of armatures, and moves the movable contact by the magnetic field generated by the electromagnet, wherein a magnetic circuit formed by the magnetic core, the yoke and the pair of armatures is closed at the opened state, and is opened at the closed state.

The link member is capable of pressing the contact piece. The link member includes a first pressing portion and a second pressing portion. The first pressing portion is configured to press the first divided piece, and extends in a widthwise direction of the contact piece. The second pressing portion is configured to press the second divided piece, and extends in a lengthwise direction.

A relay, includes a base; a contact part disposed on the base and including two sets of movable contact parts, each set of the movable contact parts including a movable contact piece, a movable contact unit and a static contact unit, stiffnesses of two movable contact pieces are difference; a push rod assembly including a first push rod and a second push rod respectively connected to the two movable contact pieces; and a magnetic circuit part arranged on the base for driving the movements of the first push rod and the second push rod in an opposite directions, so as to drive the two movable contact pieces to come into contact or move away from each other, achieving contact or separation between the static contact unit and the movable contact unit.

A relay includes a base having a first contact area, a second contact area and a middle area between the first contact area and the second contact area; a pair of contact parts respectively arranged in the first contact area and the second contact area; each contact part including two sets of the movable contact part, each set of the movable contact part including a movable contact piece with a movable contact and a static contact on both ends, two movable contacts corresponding to two static contacts respectively in each contact part; and a magnetic circuit part on the middle area of the base for drive four movable contact pieces of the pair of contact parts through a push rod assembly to move, thereby realizing connection or disconnection of the movable contact and the static contact.

A relay includes a base, a contact part disposed on the base and including two sets of movable contact part, a push rod assembly including a first push rod and a second push rod respectively connected to two sets of movable contact parts, and a magnetic circuit part including a coil assembly and an armature assembly. The armature assembly is pivotally connected to the base around a pivot point, and includes a first driving end connected to the first push rod to form a first force point and a second driving end connected to the second push rod to form a second force point. The distance between the first force point and the pivot point is not equal to the distance between the second force point and the pivot point.

A relay includes a base, a contact part disposed on the base and including two sets of movable contact parts, each set including a movable contact piece, a movable contact unit and a static contact unit; a push rod assembly connected to two movable contact pieces; and a magnetic circuit part arranged on the base for driving the movements of the push rod assembly, so as to drive two movable contact pieces to come into contact or move away from each other, thus the contact part can transit between a connected state and disconnected state. When the contact part is in the connected state, one movable contact piece is deformed under an action of the push rod assembly and has an elastic force, which makes the movable contact piece has a moving tendency to disconnect the contacts.

A relay includes a contact part including two sets of movable contact parts, each set including a movable contact piece, a movable contact unit, a static contact unit and a movable contact leading-out piece, at least one movable contact leading-out pieces is provided with an avoidance notch; the static contact unit having the avoidance notch including at least two static contacts; and a push rod assembly including a first and second push rods, the first push rod being movably passing through the avoidance notch of one of the movable contact leading-out pieces and connected with the movable contact piece of the other the movable contact part; the second push rod being connected with the movable contact piece of the movable contact part.

A contact piece structure includes two movable contact pieces arranged side by side. Each movable contact piece includes a piece body, a movable contact and a static contact located at opposite ends of the piece body. The movable contact and the static contact of one of the movable contact pieces correspond to the static contact and the movable contact of the other movable contact piece respectively so as to form a parallel circuit structure when the contacts being in contact; Bending portions of two piece bodies are arranged one-to-one to form a bending pair; in each of the bending pairs, top ends of two bending portions are parallel with each other; two bending portions protrude along a same protruding direction, a first distance between the two bending portions is smaller than a second distance between the two ends of two piece bodies.

An electromagnetic relay including: an electromagnet; a movable spring having a movable contact; a first terminal to which one end of the movable spring is connected; a second terminal having a fixed contact opposite to the movable contact; an actuator that rotates by excitation of the electromagnet, rotates the movable spring, and causes the movable contact to come in contact with the fixed contact or to separate from the fixed contact; a nonmagnetic card to be attached to the actuator; a plurality of magnetic members that sandwich the movable contact and the fixed contact, and apply a magnetic flux to the movable contact and the fixed contact to extend an arc; and a permanent magnet attached between the magnetic members.

A power contactor having an electromagnetic driving unit, a rotating armature, and a reset element. The rotating armature is switched by the electromagnetic driving unit between an open position and a closed position. The reset element exerts a reset force onto the rotating armature when in the closed position.
