1. A switch cabinet comprising a switch cabinet door which closes the switch cabinet and has a door lock which can be actuated via a door handle, the switch cabinet door having a door status sensor which has a magnetic field sensor being adapted to distinguish an open state of the switch cabinet door from a closed state of the switch cabinet door by means of a detected geomagnetic field change, wherein at least the magnetic field sensor of the door status sensor is accommodated in a region of the door handle within the door handle which is magnetically permeable to the environment of the switch cabinet and is coupled to the geomagnetic field via the magnetically permeable region, wherein the door handle has a ferromagnetic base, via which the door handle is placed on an outer side of the switch cabinet door, and a cover, between which and the base the door status sensor is arranged, the cover having the magnetically permeable region and/or consisting entirely of a magnetically permeable material.
