Abstract: A remotely controlled circuit control device has first and second load contact assemblies movable into circuit engagement and circuit disengagement positions relative to one another in which one load contact assembly is operatively connected to a solenoid so that alternate forward strokes of the solenoid moves the one load contact assembly between reset and tripped positions through a push-push mechanism having an indexing portion and a latching portion. An overload mechanism cooperates with the latch portion to cause the load contact assemblies to move to the circuit disengaged position upon occurrence of a fault condition. The second load contact assembly includes pivotably mounted contact members which are linked to the first load contact assembly in such a way that circuit engagement during solenoid energization is precluded.

Abstract: An electric circuit switchgear includes main contacts circumferentially arranged on a fixed panel and auxiliary contacts. The switchgear also includes a rotary electromechanical drive connected with a driving shaft and enabling the latter to be turned through a pre-set angle. The driving shaft is rotated together with an actuating element of an electromagnetic drive provided with a contactor and a disconnector both having at least one projection interacting with the main and auxiliary contacts through contact closing and disconnecting mechanisms having locks.

Abstract: An electrical switching device is disclosed comprising a first and a second support member engageable with one another forming a housing. A plurality of first and second contacts are mounted to the support housing and urged to be in contact with one another. A switching member such as an insulator having a plurality of contact apertures and a plurality of indexing apertures is movably mounted to the support housing and interposed between the first and second contacts. The insulator switching member separates some of the first and second contacts and allows electrical engagement of the others of the contacts through the contact apertures. The invention includes indexing means comprising a solenoid and an indexing member having an indexing arm to engage with an indexing aperture to move the switching member and the contact apertures to cause engagement or disengagement between the plurality of first and second contacts.
