Abstract
A switching configuration includes a first switching contact set having a rated current contact piece and an arcing contact piece. The arcing contact piece and the rated current contact piece of the first switching contact set are movable relative to one another through a transmission mechanism. The arcing contact piece is supported by a support element on a contact carrier of the rated current contact piece. The transmission mechanism has a transmission mechanism chassis which is supported, particularly directly, on the contact carrier.
Claims6
A switching configuration, comprising:
- a first switching contact set having a rated current contact piece and an arcing contact piece being movable relative to one another;
- said rated current contact piece having a contact carrier with a cavity having an orifice opening, said arcing contact piece protruding into said cavity;
- a supporting element supporting said arcing contact piece on said contact carrier;
- and
- a transmission mechanism generating a relative movement between said arcing contact piece and said rated current contact piece, said transmission mechanism having a transmission mechanism chassis supported on said contact carrier;
- said transmission mechanism chassis having at least one bearing flank supported directly on and fixed to said contact carrier, said at least one bearing flank spanning said supporting element at a spacing, and said at least one bearing flank including a transverse crosspiece spanning and extending over said orifice opening.
