    摘要: A hybrid current switching device comprises two terminals for electrical connection with an associated electrical circuit and a casing containing: - a main current switch (MS) comprising a first fixed contact and a corresponding first movable contact which are connected in series with and positioned between the two terminals; - a power switch device (PES) which is connected in parallel with the main current switch and can be switched between an on-state and an off-state; - a secondary current switch (IS) having a second fixed contact and a second movable contact, the secondary current switch being connected in series at least with the power switch device; - a movable-contacts holding shaft (4) on which the first and second movable contacts are mounted. The contacts-holding shaft is positioned inside the casing rotating around a rotation axis so as to move the movable contacts between a closed position where they are coupled with the corresponding fixed contacts and an open position where they are electrically separated there from; the first and second movable contacts are mounted on the rotating shaft with an angular offset relative to each other when being in the open position.

    摘要: A latching mechanism (10) for activating a switch, a switch comprising a latching mechanism (10) described herein, and a method of unlatching a latching mechanism (10) are described. The latching mechanism (10) comprises a latch element (12), at least one linear actuator (11), and a first clamp element (13), wherein the latching mechanism (10) is configured to change between a latched state and an unlatched state. In the latched state the at least one linear actuator (11) is extended along a longitudinal axis (20) and presses the latch element (12) against the first clamp element (13) to thereby establish a frictional locking between the latch element (12) and the first clamp element (13). In the unlatched state the at least one linear actuator (11) is contracted along the longitudinal axis (20) thereby releasing the frictional locking between the latch element (12) and the first clamp element (13) to thereby allow a movement of the latch element (12) for activating the switch.

    摘要: An electrical switching apparatus (2;50) includes separable contacts (10), an operating mechanism (16) structured to open and close the separable contacts, and a trip mechanism (14) cooperating with the operating mechanism to trip open the separable contacts. The trip mechanism includes a trip latch (4), and an arc chamber (18) operatively associated with the separable contacts. The arc chamber includes a plurality of arc plates (20) and a barrier (22) disposed between the arc plates and the trip latch. The barrier has an opening (12;58) therein. A trip member (8) is disposed in or about the opening of the barrier of the arc chamber. During interruption of current flowing through the separable contacts, pressure arising from an arc (11) in the arc chamber pushes the trip member away from the barrier of the arc chamber to engage the trip latch and cause the trip mechanism to trip open the separable contacts.
