Abstract: A device, used in particular in telecommunications technology to supply power to parallel-connected, electrical loads has side-by-side arranged potential lines. These are secured inside a connecting housing, with connections for supplying the operating potential. The connections supply plug-in modules for connecting individual loads, which modules are fitted against the connecting housing in longitudinal direction of the potential lines. The potential lines are configured as rigid, parallel bus bars that project on a side from the connecting housing. With the aid of passages that make contact with the bus bars, the plug-in modules are fitted side-by-side onto the bus bars, such that they fit against the connecting housing or against each other, and are frictionally secured.

Located between the parallel side walls of the housing sections is a switchgear with a contact bridge, the movement of which is guided parallel to the side walls and which extends in essentially longitudinal direction at a right angle to the side walls and while in the on position between two fixed contacts that are fastened inside the housing and are positioned on both sides of the movement plane for the switchgear. The fixed contacts are flat pieces akin to a knife blade and fit against the side walls and, respectively, form a contact point with their narrow, knifeblade type edges facing the contact bridge. With their rear sides opposite the contact points, the fixed contacts fit against a flank wall of housing. As a result of this, the fixed contacts are positioned in an especially space-saving manner in the corners of housing.

Abstract: An electric switch (1) includes a switching device (4), movable between its ON position and OFF position, for switching a current circuit. The switch (1) is combined with a magnetic circuit (28, 29) for electromagnetic undervoltage tripping. In the event of undervoltage, the magnetic circuit (28, 29), as it opens, shifts the switching device (4) to its OFF position. The switching device (4) shifted to its OFF position closes the magnetic circuit (28, 29) again. A linearly movable fixing slide (24) couples the switching device (4) with the magnet armature (28) of the magnetic circuit and fixes the magnet armature (28) on the magnet core (29) in the OFF position of the switching device (4).

Abstract: An electrical instrument switch includes a rocker switch for manual on-and-off switching and that is seated in an insulation housing. Depending on the pivot position, the rocker switch moves, with a working end that dips into the housing interior, a contact bridge between the closed position of its contact and the open position of its contact. The contact bridge is electrically connected in series with a contact spring that can be triggered thermally and hence acts as an overcurrent protection. The contact spring can move between its contact position and its open position. The contact spring is mechanically prestressed in the direction of its open position. When overcurrent occurs, it is transferred out of its contact position into its open position by a thermal triggering element. A pivot of the rocker switch counter to the mechanical prestress, in the tipping direction of the contact spring, guides the contact spring from its open position back into its contact position.
