The pushing rod assembly is composed of a pushing rod part and a U-shaped basket as two separate parts, the pushing rod part includes a fixing piece and a pushing rod fixed together with insulating plastic. The movable spring part and the U-shaped basket are mounted on the top of the pushing rod part, the two ends of the fixing piece are secured to the bottom of the side part of the U-shaped basket. The main spring is tightened between the bottom surface of the movable spring part and the insulating plastic of the pushing rod part, and the movable spring of the movable spring part is pressed to the inner side of the top part of the U-shaped basket.

A switching device, for the on-off switching of a current passing through a current path, has at least one fixed contact and at least one movable contact, wherein the movable contact can be moved relative to the fixed contact for making or breaking the current path, and a drive for the functional movement of a jumper between a contact-making position and a contact-breaking position. In the contact-making position with the fixed contact, the movable contact makes the current path. The switching device includes a high-speed circuit breaker for breaking the current path in the event of a short circuit or overload, wherein the armature of the high-speed circuit breaker is rigidly coupled to the movable contact.

A contact slide unit for a switch unit, where the contact slide unit includes a contact slide with a switching piece displaceably guided therein, and method for mounting the contact slide unit, where the displaceable switching piece is protected on the contact slide against twisting via a separately formed anti-twist stop.

A contact device (15) of a starter contactor (1) comprising:a contact rod (17) made of an electrically insulating material,a contact strip (19) made of an electrically conducting material comprising a hole (19a) in which is mounted the contact rod (17),a squashing spring (25),a restoring spring (27), the contact device (15) also comprises a closure clip (33) of radial width greater than or equal to the diameter of the squashing spring (25), a radial notch (33a) being made in the closure clip (33), the radial notch (33a) receiving a portion of the contact rod (17), the squashing spring (25) being mounted compressed between the closure clip (33) and the contact strip (19) which is in abutment on a retaining collar (17a) of the contact rod (17).

A switching device has a switching chamber; a plate-like switching element, which can be moved in the switching chamber along a linear movement axis (Z) between an ON position in which the switching element connects fixed contacts to one another, and an OFF position in which the switching element is at a distance from the fixed contacts; an actuator for linear movement of the switching element inside the switching chamber; and spring(s) which prestress the switching element in the direction of the movement axis (Z). Guides are provided and configured so the switching element in the switching chamber is guided along the movement axis (Z) in a linearly movable manner and held so a main axis (N) of the switching element, which runs perpendicularly with respect to the two main extension directions (X, Y) of the switching element, is oriented at least substantially parallel to the movement axis (Z).

A contact bridge arrangement for an electrical switch, such as a contactor or a relay, is disclosed. The contact bridge arrangement comprises a contact bridge having a contact bridge body, an actuating member on which the contact bridge is held that is movable with respect to the contact bridge along an actuating direction, the actuating member having a stop and a spring base, and a spring disposed between the spring base and the contact bridge body pressing the stop against the contact bridge.

A contact bridge arrangement for an electrical switch is disclosed that has a contact bridge holder and a contact bridge. The contact bridge holder is monolithically formed with a spring. The contact bridge is held on the contact bridge holder and movable along an actuating direction. The contact bridge is pressed against the contact bridge holder by the spring.

A carrier sub-assembly for an electrical relay device includes a plunger and a shaft. The plunger is formed of a ferromagnetic material. The plunger has a generally cylindrical shape extending between a top side and a bottom side of the plunger. The shaft extends between a contact end and an opposite plunger end. The shaft is directly secured to the plunger without a discrete component between the shaft and the plunger securing the shaft to the plunger. The shaft and the plunger are configured to move together within the electrical relay device. A segment of the shaft including the contact end protrudes from the top side of the plunger for securing to a movable contact of the electrical relay device.

The disclosure relates to a contact slide unit for a switching unit, including a contact slide inside which a movable contact piece is guided, wherein the contact piece is biased from one side by a contact load spring. The disclosure also relates to a method for assembling the contact slide unit. The disclosure is characterized in that the movable contact piece is mounted in a winding interstice between two windings of the contact load spring.

A crossbar structure of an electromagnetic contactor is provided, specifically, a crossbar structure of an electromagnetic contactor in which consistent performance is attained by preventing a moving mount from being flipped. The electromagnetic contactor includes a crossbar configured to move up and down and a moving contact point disposed on an installation groove, which is formed on the crossbar in a vertical direction, and brought in contact with or separated from a fixed contact point. The installation groove includes an insertion part into which the moving contact point is inserted and assembled and an operating part closely formed enough to prevent the moving contact point from being flipped when the moving contact point moves up and down.
