Abstract
A drive control apparatus interconnects with a venetian blind slat ladder assembly for positioning the blind slats at any desired angular relationship and includes a detent that is moved during slat positioning and when a limit stop is reached exerts a back pressure onto the drive apparatus. When the back pressure exceeds a predetermined amount, this causes the drive shaft to overcome a retarding leaf spring pressure and thereby slip rather than drive the slat ladders.
