摘要： Provided is a switch that can be downsized. A switch is provided with a plunger, and an upper torsion spring configured to bias the plunger in a returning direction. The torsion spring has a first arm that extends to the plunger and abuts against the plunger. The plunger has a hole at a position into which the first arm is inserted. The hole is a through hole extending in a direction that is perpendicular to a direction in which the plunger moves, and is the same as a direction in which the first arm extends when viewed in the direction in which the plunger moves.

摘要： The contact device (30) for the electrical switch comprises a first connection element (31), a second connection element (32) and a movable contact bridge (33). Furthermore, the contact device (30) comprises at least two magnets for extinguishing arcs which arise during the switching of the electrical switch. The magnets generate a magnetic field in a first region which comprises at least one first contact region and one second contact region, in which contact regions, with the electrical switch in a closed switching position, the first connection element (31) and, respectively, the second connection element (32) are in contact with the contact bridge (33). In addition, the contact device (30) comprises one or more deflection elements which are arranged and designed to distort the magnetic field in such a way that a first arc which forms between the first connection element (31) and the contact bridge (33) and a second arc which forms between the second connection element (32) and the contact bridge (33) are forced into different directions, which extend pointing away from one another, independently of a respective flow direction in the connection elements (31, 32).

摘要： A compact fusible disconnect switch device includes a magnetic arc deflection assembly including at least a pair of magnets disposed about a switch contact assembly. The magnetic arc deflection assembly facilitates reliable connection and disconnection of DC voltage circuitry well above 125 VDC with reduced arcing intensity and duration. Multiple pairs of magnets may apply magnetic fields in directions opposing one another to deflect electrical arcs in different directions at more than one location in the switch contact assembly to facilitate high voltage DC operation.

摘要： In present disclosure, a movable bar guide portion (133) is formed to protrude toward a movable bar in a shaft having a movable bar (120), and when a fault current is applied and the movable bar is rotated due to electromagnetic repulsion force, the movable bar and the movable bar guide portion contact each other, and thus, when the movable bar is rotated through the movable guide portion, movement of a rotation center of the movable bar is minimized.
