摘要： A latching mechanism is for locking a spring energy store of an electric switching device. The store is tensioned by a rotary drive and an extensible lever system. In the latching mechanism, the extensible lever system is locked with the spring energy store under tension by way of a support element, an auxiliary lock and a primary lock, in addition to a stop that is allocated to the primary lock. The auxiliary lock can be pivoted by the extension of the lever system and the position of the primary lock during the pivoting of the auxiliary lock can be influenced by working surfaces that are allocated to one another. To configure the locking mechanism for pivoting the primary lock in a manner which obviates the use of a return spring that acts on said primary lock, the auxiliary lock and the primary lock respectively have at least two working surfaces. In a first pivoting phase of the auxiliary lock, the respective first surfaces of the two sets of working surfaces lie adjacent to one another and in a second pivoting phase of the auxiliary lock, the second working surfaces lie adjacent to one another, intermeshing in the manner of a toothed gear.

摘要： The energy store is coupled to the drive train for operation of a movable contact via a lever (25) and has an energy storage spring (19) held between a stationary counter-bearing (17) and a movable counter-bearing (18) via a U-shaped support platform (20) fitted with the stationary counter-bearing. The support platform, the energy storage spring and the 2 counter-bearings form a self-supporting unit secured to the switch carrier adjacent one counter-bearing, the support platform having 2 adjacent rod elements (21,22) transverse to the working direction of the storage spring secured to the switch carrier, with a stop for the movable counter-bearing provided by an associated shock absorber (23).

摘要： An isolating contact or disconnect arrangement for connecting or disconnecting mutually relatively movable busbars, comprises a block of laminations and bridge-type contact laminations arranged mutually parallel and relatively movable to one another in the laminations block. The contact laminations have contact surfaces at their ends for positioning on the busbars to be connected or disconnected, and they are spring- pretensioned against the busbars. The contact laminations (5) located parallel in the laminations block (1) are each pierced by a support bolt and a travel roller (7) is rotatably arranged on end of the support bolts (6). The busbars (8) operating together with the contact laminations (5) have recesses (9) for dipping the travel rollers (7) in the end position of the installed power switch.

摘要： PCT No. PCT/DE95/00491 Sec. 371 Date Oct. 10, 1996 Sec. 102(e) Date Oct. 10, 1996 PCT Filed Apr. 10, 1996 PCT Pub. No. WO95/29496 PCT Pub. Date Nov. 2, 1995A bearing arrangement for an operating shaft of a multi-pole electric switching device with a chassis formed by central and outer walls that are parallel to each other. The bearing arrangement comprises shaft bearings in the form of half-shells. The central walls, which are designed to accommodate the shaft bearings, are each provided with an open recess at its edge. The recess has one bordering edge that corresponds to the radius and width of a groove located on the outer periphery of the half-shells and another bordering edge that corresponds to the outside diameter of the half-shells. A locking piece is attached to the respective wall and secures the half-shells after they have been assembled on the operating shaft.

摘要： PCT No. PCT/DE95/01520 Sec. 371 Date Aug. 1, 1997 Sec. 102(e) Date Aug. 1, 1997 PCT Filed Oct. 30, 1995 PCT Pub. No. WO96/13842 PCT Pub. Date May 9, 1996The arrangement for mutually locking the actuation of at least two power switches (A, B, C) has a position indicator (7) and an evaluation apparatus (10) for each power switch (A, B, C). A carrying plate (6) accommodating the position indicator (7) and the evaluation apparatus (10) is assigned to a side wall of the power switch (A, B, C). A shaft coupling (30) and a driver coupling (31) establish the connection with a switching shaft or a control shaft, respectively, of a device (32) that releases or locks the actuation of the power switch (A, B, C) when the carrying plate (6) is mounted on the power switch (A, B, C) or on a withdrawable rack (26).
