1. An apparatus for the sequential switching of at least one first venetian blind and at least one second venetian blind each comprising slats which are synchronously rotationally moveable by at least one respective coupling rod to open and close the-venetian blinds, the apparatus comprising:
an actuator for generating a rotary movement of the slats through 80° to 90°,
a coupling for rotatably coupling the actuator to the slat of the first venetian blind,
a link rod having a part-circular guide, and
a transmission rod,
wherein the actuator has an eccentric pin parallel to an axis of rotation of the actuator, which engages into the part-circular guide of the link rod,
wherein a fixed, rotatably mounted transmission rod is provided which has pivot levers attached thereto, wherein the link rod acts on the pivot lever to rotate the transmission rod and the pivot lever acts on the coupling rod of the at least second venetian blind, so that the linear movement of the link rod can be transmitted via the transmission rod to the coupling rod of the at least second venetian blind.
