An actuation device for movement of a barrier comprising a gear motor adapted to transmit a rotary motion to a tubular support, integrally connected to said barrier and rotating with respect to a fixed support. The actuation device comprises actuation means manually operable by a user and reversibly movable between a position decoupled from, and a position coupled with, a microswitch to start/stop a detection procedure of an end-of-travel position for said gear motor. |
