Abstract

A limit switch (1), particularly for one or more blinds or awnings which can be rolled up onto a hollow drum which can be actuated by an electric motor (2) which is accommodated in an appropriately provided tubular element (3) inserted coaxially with respect to the drum, comprising a first stem (5), which is approximately cylindrical and hollow and can be inserted at one end of the tubular element (3) and with which a ring (6) is rotatably associated, the ring (6) being associable with the drum by keying and having, on its internal surface, a set of teeth (7) which interacts with a first sprocket (8) which is supported rotatably within the first stem (5). The first stem (5) is connected, on the opposite side and externally with respect to the drum, to a box-like body (11) which accommodates internally a first gear system (41a) and a second gear system (41b), which interact selectively with the first sprocket (8) and are adapted to actuate respectively two switches, the pressing of which stops the electric motor (2) and brings the motor to a condition in which it can subsequently rotate only in a direction which is the opposite of the preceding one.
