An electrical switching device includes a first switching contact piece and a second switching contact piece. The switching contact pieces can be displaced in relation to each other. The first switching contact piece is surrounded by a fluid flow guiding device. An enveloping contour of a flow duct, disposed between the fluid flow guiding device and the first switching contact piece, is greater at its end facing the second switching contact piece than an enveloping contour of the first switching contact piece at its end facing the second switching contact piece.
