A switching device for direct-current applications includes a housing having a first wall and a second wall, a plurality of receiving areas for respective mutually substantially parallel current paths disposed in the housing. Each of the current paths has a respective stationary switching contact element and a respective movable switching contact element, the movable switching element being actuatable into a closed position and into an open position so as to form a respective air break, the respective movable switching contact elements being actuatable simultaneously. The switching device includes a plurality of arc-quenching devices associated with the current paths and disposed next to each other, and at least one magnet. The at least one magnet is configured to generate a magnetic field so as to generate a deflection force on the arcs so as to deflect the respective arcs toward at least one of the respective arc-quenching devices.

摘要:
The invention relates to a method for effecting an electronic drive control of a drive coil of a protection system using an electronic device which comprises a microcontroller. The aim of the invention is to increase the serviceable life of a protection system. To this end, the invention uses a randomly selected and constantly changing delay time (tx) that occurs after a time (t2, t3) at which the supply voltage is established on the electronic device.
摘要:
The projectile weaving machine is provided with a retractor apparatus at the braking device in which an elastically yielding and damping body is disposed to absorb impact forces and damp vibrations. The elastically yielding and damping body is located between the stop surface of the retractor and a fulcrum between the retractor and a lever for moving the retractor within the apparatus. In some embodiments, the body is positioned between two parts of the retractor while in other embodiments, the body may be disposed between the retractor and the moving means or may be incorporated in the retractor itself.
