Definitions

  • the invention relates to a switching mechanism for low-voltage switching devices according to the preamble of claim 1.
  • Such a switching mechanism for actuating the electrical contacts of a switching device is already known (DEP 35 08 110).
  • the switching mechanism described there has a locking member, which has the task of locking the switching contacts shortly before touching them.
  • the preloaded blocking element holds a switching axis, which establishes the transmission to the switching contacts of the switching device, via a disk up to a selectable switch-on force on the switching knob.
  • energy is stored by elastic deformation of the switching elements between the switching knob and the switching axis.
  • the prestressed locking member is deflected and the disk of the shifting axis rolls on a circular contour of the locking member.
  • the disk comes out of the engagement of the blocking element and the switching axis swings in the switching-on direction and thus causes the switching contacts of the switching device to switch on suddenly.
  • a switching mechanism for actuating an electrical contact of a switching device is also described, which has a jump switch for the sudden switching on of the switching contacts of the switching device. It has now been found, however, that in certain cases it is not necessary to use a complex device for switching on suddenly in such a switching device.
  • the invention is based on the object of developing a switching mechanism for a residual current circuit breaker which can be inexpensively produced based on a powerful mechanism by using simple parts and which fulfills the technical requirements without switching on.
  • An embodiment of the invention is shown in a drawing and is explained in more detail below. It shows the only figure a switching mechanism for a residual current circuit breaker in side view.
  • the residual current circuit breaker can be switched on and off manually by a switching lever 4 .
  • the shift lever 4 is connected to a toggle lever system which consists of three lever-like tabs 1 , 2 and 3 .
  • the toggle lever system has a common joint 5 . While the tab 1 is connected to the switching lever 4 , the tab 2 is connected to a contact shaft 6 , on which a movable contact 8 is attached. This movable contact 8 corresponds to a fixed contact 9 .
  • the tab 3 which is also connected to the joint 5 , is articulated at its free end to a rocker arm 7 .
  • the tab 1 is made of stamped material.
