摘要：The actuator device (1) comprises a fixed support structure (2; 3, 4), an actuation member (8) movable relative to the structure (2), a contrast member (13) tending to maintain the actuation member (8) in a rest position, a shape-memory wire (10) having a first end connected to the structure (2) and the other end connected to the actuation member (8), and an electric circuit for supplying an electric current to the shape-memory wire (10). The circuit comprises a pair of terminals (6, 7) carried by the structure (2), for connection to external control circuits. One end of the shape-memory wire (10) is connected to a first terminal (6) of said pair (6, 7). The circuit comprises further an electric switch (11, 8d), including a first conducting member (11) electrically connected with the second terminal (7), and a second conducting member (8d) carried by the actuation member (8) and electrically connected with the other end of the shape-memory wire (10). The switch (11, 8d) is closed when the actuation member (8) is in the rest position, and remains closed until when the actuation member (8) reaches a working position, and opens when the actuation member (8) passes beyond the working position.
