Abstract
An electric switching device contains a first contact piece and a second contact piece. The first contact piece can be driven by a first kinematic chain. The second contact piece can be driven by a second kinematic chain. The electric switching device contains a first switching point and a second switching point, which are electrically connected in series, the first contact piece being associated with the first switching point and the second contact piece with the second switching point.
Claims8
An electric switching device, comprising:
- a first contact piece;
- a second contact piece;
- a first kinematic chain for driving said first contact piece;
- a second kinematic chain for driving of said second contact piece, said first kinematic chain and said second kinematic chain operate in a mutually independent mechanical arrangement independent from each other;
- a first switching point being associated with said first contact piece;
- and
- a second switching point connected in series with said first switching point, said second contact piece being associated with said second contact point.
