Beschreibung
Zusammenfassung:	The invention relates to an electric switching device (1), comprising at least one switching-device pole filled with insulating gas and a monitoring apparatus (14). The monitoring apparatus (14) comprises a density monitor (15) and a housing part (16), wherein a gas chamber (17) is contained in the housing part (16), which gas chamber is connected to the switching-device pole and to the density monitor (15) and can be connected to a testing device for the density monitor (15), and wherein the housing part (16) contains a shut-off element (20), which can be actuated into an open position and into a closed position. The actuation of the shut-off element (20) is independent of the connection of the gas chamber (17) to the testing device.
