Abstract: A locking device for a switch cabinet has at least one locking rod for locking the door of the switch cabinet. An actuating element for displacing longitudinally the at least one locking rod for locking and unlocking the door is provided. A handle is connected to the exterior of the door so as to be foldable and rotatable. The handle has a transmission shaft for coupling the handle to the actuating element which is activated by rotating the handle. A plate-shaped member is connected to the exterior of the door and has a depression for receiving the handle. In its folded position the handle is flush with the plate-shaped member. The plate-shaped member has a receiving portion adjacent to the depression. At least one lock for locking the handle is positioned in the receiving portion at an angle relative to the plane of folding of the handle. A transmission element is coupled to the lock and slidable within the receiving portion for locking and unlocking the handle when acted upon by the lock.
