Abstract

The electrical switching device comprises an outer enclosure, at least one housing for receiving a removable auxiliary block, the enclosure including a base and a cover, the cover being configured to cooperate with the base to close the outer enclosure.
The cover includes signaling units movable between an inactive position and an active position, and control units configured to move the signaling units from the inactive position toward the active position during closing of the enclosure if at least one auxiliary block is present in a corresponding receiving housing.

First claim

The invention claimed is:

1. An electrical switching device comprising:
an outer enclosure; and
at least one receiving housing for receiving a removable auxiliary block, the outer enclosure including a base and a cover, the cover being configured to cooperate with the base to close the outer enclosure,
the cover including at least one signaling unit movable between an inactive position and an active position, and at least one control unit configured to move a corresponding signaling unit from the inactive position toward the active position during closing of the outer enclosure when at least one auxiliary block is present in a corresponding receiving housing, each signaling unit including a signaling member, wherein
at least one control unit and a corresponding signaling member are monolithic with respect to each other,
each signaling member is a tongue, the cover includes an inner face and an outer face that are parallel to each other, the inner face being oriented toward an inside of the outer enclosure, and the tongue being translatable parallel to said inner face along a translation direction, and
the at least one control unit including a bearing face angled with respect to the translation direction and bearing against the auxiliary block to move the signaling member to the active position during closing of the outer enclosure.

2. The switching device according to claim 1 , wherein the signaling units are translatable relative to the cover.

3. The switching device according to claim 1 , wherein the signaling units include a signaling member for each receiving housing, and the control units are configured so as, upon closing of the outer enclosure, to move each signaling member from its inactive position toward its active position when an auxiliary block is present in the receiving housing associated with said signaling member.

4. The switching device according to claim 1 , wherein the signaling units include a signaling member for each receiving housing, the control units being configured so as, upon closing of the outer enclosure, to move each signaling member from its inactive position toward its active position when an auxiliary block is present in the receiving housing associated with said signaling member.

5. The switching device according to claim 3 , wherein the cover includes a viewing window for each receiving housing, each signaling member being, in its inactive position, invisible from outside the outer enclosure, and in its active position, visible through the viewing window associated with said receiving housing and said signaling member.

6. The switching device according to claim 5 , wherein the switching device further comprises a closing off element placed across from each viewing window when the cover is in the closed position, each signaling member being, in its active position, configured to be inserted between the viewing window and the closing off element.

7. The switching device according to claim 1 , wherein the switching device comprises at least one removable auxiliary block.

8. The switching device according to claim 7 , wherein each auxiliary block is an auxiliary contact.

9. The switching device according to claim 1 , wherein the switching device is a circuit breaker.
