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.

Electric switching device

An electric switching device includes first and second switch contact pieces. The first switch contact piece has a guide portion. The first switch contact piece is connected to an actuating unit or drive device by a kinematic chain. The guide portion of the first switch contact piece is guided on a guide path. The guide portion and the guide path each have a contact or bearing surface and at least one of the contact or bearing surfaces is convexly curved.
