<p>1. A central door locking device, especially for motor vehicles, having several electromotive actuator units (5) connected to a parallel circuit (6), at least one operating switch with a first and a second switch setting which allows the actuator units to be driven, and a timing element which allows the drive circuit of the actuator units to be broken and a further drive circuit to be enabled, characterized in that the timing element comprises a changeover switch (7, 7'), an electromotive servo motor (8, 8') which behaves like the electromotive actuator units (5) under varying operating conditions, and an actuator member (14, 14') of the servo motor (8, 8'), and on the line side of the parallel circuit (6) is connected the changeover switch which after respective half-cycles of the servo motor (8, 8') can be reset by the actuator member (14, 14') of the servo motor (8, 8') either from a position connected to one switch setting of the operating switch (11) to a position connectable to the second switch setting of the operating switch (11) or else from a switch setting connected/not connected to a positive pole (10) to a switch setting connected/not connected to a positive pole (10), the servo motor (8, 8') being connected on the load side of the operating switch (11) and each operating switch (11) being resettable by an actuator (15) of the associated actuator unit (5) such that all operating switches (11) always assume the same switch setting.</p> |
