An auxiliary contact block is disclosed for expanding a switching device and to a switching device having at least one auxiliary contact block. A compact auxiliary contact block, i.e. a block requiring little wiring and space, for a switching device is disclosed, and a switching device having at least one auxiliary contact block. In at least one embodiment of the auxiliary contact block, the auxiliary contact block includes auxiliary contacts disposed in a plane, the contacts having contact bridges and associated fixed contact pieces, and at least one contact slider, which can be equipped with at least one auxiliary contact pair. The configuration of the auxiliary contacts in a plane as described herein allows a very small installation size and very little wiring complexity of the auxiliary contacts in a simple manner. The actuating unit can, for example, be configured as a slider that couples the contact slider and the switching device with each other.

A switchgear includes a power supply built into a common housing, and at least two drives. The power supply can be fed by an external supply voltage and an external consumer can be connected to the two drives. In at least one embodiment, the switchgear includes, in the same housing, a built-in overload detection for the two drives and/or a built-in circuit breaker function for the two drives, and/or a built-in control circuit for the common control of the two drives. The switchgear can optionally be completed by a transformer providing an additional function of the targeted charging of a buffer capacitor and/or by an energy accumulator providing an additional function of the targeted discharge thereof by temporarily switching on a connected consumer.

A switching device unit is disclosed for switching at least two operating states of at least one consumer to an at least two-phase electrical supply system by way of switching elements. At least one embodiment of the invention specifies a switching device unit which has as simple a construction as possible and is as cost-effective and compact as possible. For this purpose, the switching device unit contains circuits for operational switching of the consumer, for implementing the tripping function for protection against overload and short circuits, wherein these circuits are integrated in such a way that the switching device unit, in particular in terms of its function as a compact reversing starter, can have a standardized width in order to be installed in a space-saving manner on a top-hat rail in a switchgear cabinet and in order to be operated.

A magnetic chamber is disclosed for electromagnetic low voltage switchgear, especially a compact reversing starter, including two magnetic drives which are each actuated by a main slide. The magnetic chamber is designed, in at least one embodiment, to receive both magnetic drives of the electromagnetic low voltage switchgear, and a mechanical reversing locking device held in a mobile manner for the alternating mechanical locking of the two magnetic drives is arranged in the magnetic chamber, the mechanical locking device acting on the two main slides. An electromagnetic low voltage switchgear is disclosed, especially a compact reversing starter, including two magnetic drives which are each actuated by a main slide, both magnetic drives being arranged in a magnetic chamber. The mechanical reversing locking device held in a mobile manner, in at least one embodiment, engages with the main slide of one of the magnetic drives, according to the position of the locking device, in order to fix said magnetic drive.

The binding for a sports apparatus, particularly for a snowboard, ski, monoski, or snowshoe, with rotary closure, has a hub (34) fixed to the sports apparatus, about which hub a binding support plate (19) is rotatingly disposed. The binding support plate (19) is fixable in relation to a hub in the running position, and two binding bodies having holding means for a boot are secured thereto. Connected to the hub fixed to the sports apparatus is at least one element (36) receiving pulling and/or pushing forces, one end of which engages the hub (34, 35), and the other end of which is coupled to a holding device. Upon rotation of the binding support plate (19), the holding device fixes a boot in the binding or releases it as a function of the position relative to the hub through co-operation with the element (36) receiving pulling and/or pushing forces.

A water discus having a round, outwardly bulging plastic body having a hollow interior and a smooth water gliding exterior surface, and mounted on the periphery of the body an impact protection element in the form of a toroid generated by a circle. The hollow body is made up of a bottom section and a cover having a closable aperture. The cover is in clamping engagement with the bottom section. The bottom section has an annular wall laterally enclosing the hollow interior of the body. The height of the wall is less than the diameter of the circle. The bottom section has a floor which supports the wall and has a portion extending laterally beyond the wall. The floor also has an outwardly bulging obverse surface. The aforementioned laterally extending portion, and particularly an annular ridge formed thereon, supports the impact protection element. The minimum distance between an exterior point on the protective element and the obverse surface of the floor is no greater than 3 mm.

It is normal practice in automation to network individual components of an installation via bus lines, with this network carrying out a multiplicity of communication and supply tasks during operation. In at least one embodiment, a system interface, as well as an installation which uses this interface, are disclosed with the operational reliability of the installation being improved. In at least one embodiment, a system interface is proposed for connection of a bus line to an actuator assembly in a control system with a K connection for connection of a communication channel and with a K-U connection for connection of a communication voltage supply channel, and an A-U connection for connection of an actuator voltage supply channel.
