Abstract
A closure for a switchgear cabinet door, machine case or the like, having a safety device. A lock is attached to the switchgear cabinet door, machine case or the like with a first locking element, and a second locking element is attached to the door frame, machine case frame or the like. Both locking elements can be brought into and out of functional connection with each other under the control of an electric signal. Additional locking of the closure can be simply achieved with commercially available locks because the lock has a turnbuckle, which can be rotated by 90.degree., as the first locking element, and an electromagnet is attached to the door frame or the machine case frame, whereby a locking member as the second locking element can be displaced into and out of the pivot range of the turnbuckle.
