An overload protection switch with reverse restart switching structure, particularly to one that has a molded-case circuit breaker which adding a lampshade parallel stagnation position for overload indication, and when resetting, needs to press back to the RESET for reconfirmation; due to the stagnation position and reverse restart structure, it can avoid repeating the reset action, preventing the reduction of the life of the overload protection switch and repeated exposure or the misjudgment and then resetting of electrical products that have been overloaded and tripped and then overload again then results in causing dangerous; also, the lampshade can be completely tripped even when the lampshade is suppressed, and prevent the danger of repeated tripping during overload.

A switching unit for switching an electrical current, the unit comprising separable fix and mobile electrical contacts and a mechanism capable of switching over the contacts between a closed state and an open state. The mechanism comprises a switching shaft coupled to a mobile electrical contact, a trip hook mounted to be pivoted on a fixed support of the mechanism and comprising a bore in which is housed an abutment and a link system coupling the switching shaft to the trip hook. The link system comprises an articulated linkage, which is rotationally linked with respect to the trip hook and which comprises a main bearing surface, which bears on the abutment when the switching mechanism is in the closed state. The abutment is configured to be elastically deformed when the switching mechanism passes from the open state to the closed state and the linkage exerts an effect on the abutment, so as to damp the impact of the linkage on the abutment.

An electrical switching device with separable contacts includes a switching apparatus including a fixed electrical contact and a mobile electrical contact that can be moved between a closing position and an opening position; a control lever mechanically coupled to the mobile electrical contact, the control lever being rotatable, about a first axis of rotation, between a first position and a second position; an anti-rebound lever arranged so as to move from a rest position to an opened-out position when the control lever reaches the second position. The anti-rebound lever engages a stop when it is in the opened-out position thereof and when the control lever is in the second position so as to prevent the control lever from leaving the second position.

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.
