It is provided an interrupter assembly for power distribution systems that is improved in terms of at least one of compactness, durability, synchronicity and dielectric withstand.

A switching device including a frame, a first fixed contact member having a first contact area, and a first movable contact member having a first contact arm provided with a contact area. The first movable contact member is adapted to pivot relative to the frame around a first pivoting axis between a first position and a second position. The switching device includes a spreader member that is adapted to provide a first intermediate position for the first movable contact member in which a projection of the contact area of the first contact arm overlaps at least partially with a projection of the first contact area on a switch plane perpendicular to the first pivoting axis while the contact area of the first contact arm is spaced apart from the first contact area.

An electrical switching unit with separable contacts comprises a switching device comprising: a control lever coupled mechanically to a mobile electrical contact and an anti-bounce lever, mounted on the control lever and configured to be displaced to a deployed position to cooperate with an abutment to prevent the control lever from leaving its position. The switching device comprises a fixed bearing mounted around the control lever. The anti-bounce lever comprises a contact portion which is in contact against an edge of the bearing when the anti-bounce lever is in its rest position and which is displaced along the edge when the control lever rotates about the bearing. The bearing comprises, on the edge, a guiding portion in the form of a cam configured to push the anti-bounce lever to its deployed position.

A pole unit has an actuator shaft that is rotatable about a switch axis to switch the pole unit between open and closed conditions. A linkage is configured to rotate the actuator shaft in response to movement of the handle pivotally about the orthogonal axis. The linkage includes a panel configured to rotate the actuator shaft upon sliding movement of the panel. The linkage further includes links that are pivotally coupled in series between the handle and the panel to slide the panel in response to pivotal movement of the handle.

A device for switching medium and/or high voltages has a spring-loaded drive for driving a kinematic chain. At least one energy storage spring and at least one damping element for generating a drive movement with specific drive characteristics are included. The at least one damping element is an active damping element. The damping is actively determined during switching or it is predetermined, in particular depending on environmental variables and/or the type of switching situation, by changing the settings of the at least one damping element.

A latching relay includes first and second coils and a common plunger operatively connected therebetween such that activation of the first coil moves the plunger in a first direction and activation of the second coil moves the plunger in a second direction, opposite the first direction, the first and second directions lying in a first plane. A limit switch includes a common contact and first and second coil contacts, where a position of the common contact is alternately switched between electrical connection to either the first or second coil contact based on a position of the plunger. A slide toggle accessible by a user is operatively connected to the plunger and slideable together with the plunger such that actuation of the slide toggle by the user causes manual actuation of the plunger. The slide toggle is slideable in a second plane parallel to the first plane.

A device for switching an electric current, including a switching block including a mobile electrical contact and a linking unit, integral, as well as an actuation block including an actuator and a mobile pallet. The device includes an improved connection interface, including a pivoting shaft, including an eccentric fastener element, delimiting an internal housing able to accommodate a head of the linking unit. The connection interface can be switched, by rotating the shaft, between a locked state wherein the head of the linking unit is held in the internal housing of the eccentric fastener unit so as to hold the mobile pallet integral in translation with the linking unit, and an unlocked state, wherein the head of the linking unit can move freely in translation with respect to the eccentric fastener element so as to uncouple the mobile pallet from the linking unit.
