Abstract

The switch is readily accessible from outside and it is used for switching off the drive in the upper and in the lower end position of the Venetian blind. The switching mechanism consists of reduction and differential gear driven circular control cams each with a notch. Each control cam consists of a pair of discs one fixed on its drive shaft and the other rotated in steps and automatically locked. An actuating lever has on its end a projection which engages with both notches of both discs when these notches are aligned. The control cams (14, 15, 16, 17) have coaxial shafts held on a main shaft (13) held in a partition wall (7) of the housing. Gear wheels (10, 11, 12) acts as a differential drive and two control cams (15, 16) are mounted together on the hollow stub shaft of a gear wheel (11).
