The invention is directed to a device for locking at least two protective doors of an industrial machine, in particular an injection molding machine, with a momentary contact switch, a sensor device for recognizing a closed state of the protective doors and a mechanical lock with an actuator that engages with an associated receiving device on one door. At least one non-energizable actuator is provided that engages with a receiving device associated with another protective door. In this way, several protective doors can be locked simultaneously, in particular a closing door and a discharge door of an injection molding machine.
