An electrical switching system, preferably a medium-voltage switching system, has a power switch or load switch, a disconnecting switch, and a grounding switch configured as a vacuum switching chamber. Low separation distance lengths and a more compact construction of a switching system is achieved by means of a housing in which the disconnecting switch, configured as a vacuum switching chamber, the grounding switch, and the power switch or load switch are disposed, and in which a central switch is disposed, with which the vacuum switching chambers of disconnecting switch and grounding switch can be mechanically activated. Electrical connections between connector contacts of power switch or load switch, disconnecting switch, and grounding switch can be produced.
