A switch bay (1) incorporates a door arrangement (3) with a door lock (7) that comprises a lock element (25) with a lock shaft (32). A first driver (35) is installed on the lock shaft (32) with a second driver (42) that can move axially on the lock shaft (32). The first driver (35) actuates a door bolt (27), whereas the second driver (42) works in conjunction with a control slide (30), depending on its axial position, that is dependent on a cover for an access opening (24) of a drive system (83). A probe (31) actuates a control fork (40) for the second driver (42) as a function of the presence of a switch gear (12) in the switch chamber (10).
