12. A latch arrangement for an automotive door or other closure manually operable by manual controls external to the latch arrangement, comprising:
a latch;
an electric motor controlled by an electronic control unit selectively to release the latch and to lock and unlock the latch;
a locking or superlocking electric switch or sensor connected electrically to the electronic control unit; and
a switch or sensor responsive to the latch position to send a latch signal to the electronic control unit;
the electronic control unit being responsive to the latch signal being indicative of the door or other closure being at least partly closed, and to the operation of the locking or superlocking switch, to lock or superlock the latch electrically, preventing latch release by at least one of the external manual controls.
