<p>The invention relates to a limit switching device (10) of a drive device for blinds or the like comprising a switching device which contains the electric limit switch (41, 42) for disconnecting an electric drive motor in an end position of the blind. According to the inventive limit switching device (10), means are provided for actuating the switching device. Said switching device can be driven by two concentric switching disks (11, 12) which move against one another. Individual means for operating the switching device can be coupled to one another with the assistance of the switching disks (11, 12) such that a first and second electric end limit switch (41, 42) of the switching device can be successively activated by the means while retaining the same movement direction of the blind. As a result, the interaction of the switching disks (11, 12), actuating means and end limit switches (41, 42) is optimized.</p> |
