The present disclosure relates to a direct current relay, and more specifically, to a direct current relay having a movable assembly with improved contact pressure. The direct current relay according to an embodiment of the present disclosure comprises a pair of fixed contacts, and a movable contact which is moved vertically by an electromagnetic force to contact or be separated from the pair of fixed contacts, wherein an upper yoke and a lower yoke are respectively provided on the upper and lower portions of the movable contact, a contact spring is provided on the lower portion of the lower yoke, and the lower yoke is pressed by the contact spring to move the movable contact.

A circuit interrupter includes: a first fixed terminal including a first fixed contact; a movable contactor which is formed as a separate part from the first fixed terminal and includes a first movable contact; a holding unit configured to hold the movable contactor so that the first movable contact is connected to the first fixed contact; and a squib configured to generate gas by combustion. In the circuit interrupter, pressure of the gas generated by the squib causes movement of the movable contactor in a direction away from the first fixed terminal so that the first movable contact is separated from the first fixed contact.

The present invention relates to a contactor device for high voltage applications, an energy storage system comprising the contactor device and a corresponding method for controlling the contactor device. A contactor device (100) comprises at least one fixed contact (106), at least one moveable contact (108), which is configured to move between an open position and a closed position, wherein in the closed position, the at least one moveable contact (108) electrically contacts the at least one fixed contact (106), and at least one first actuator (110, 120), which is configured to reversibly move the at least one moveable contact between the open position and the closed position. The contactor device (100) further comprises at least one second actuator (202) which is configured to move the at least one fixed contact (106) into a fired position, wherein in the fired position, the at least one fixed contact (106) is permanently disconnected from the at least one moveable contact (108).

A system called “MM System” containing a switch called “Rocking Switch” (1) capable of connecting its ON or OFF mode to a mechanical force acting on a part of it called “extension”.

The essential elements of this device are a battery source (3), a light source (2) and a Rocking Switch (1) having a swinging door (8) with an extension (10).

The Rocking switch (1) is connected to the battery source (3) and to the light source (2) that are in turn connected between them (FIG. 1).

In the embodiment in a container equipped with a traditional zipper, the extension (10) will be placed in such a way that by closing the zipper (21) the extension (10) will be moved and the Rocking Switch (1) will be opened, vice versa by opening the zipper (21) the extension (10) will come back in the rest position and the Rocking Switch (1) will be closed (FIG. 6).

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.

A high voltage relay resistant to instantaneous high-current impact is disclosed, and includes an electromagnet system, a control system, a contact system, and a base support. In the present solution, an electromagnetic force generated by the contact system is used to resolve a problem of contact separation caused by an electric repulsion force generated by an instantaneous high-current.
