A shape memory actuator comprises a supporting body (1), a driven element (7) pivotably mounted (3, 5) on the supporting body (1) and in permanent contact with a driving element (15) whose movement is determined by a SMA actuating member and by at least one resilient return member (25) acting in opposition to the SMA actuating member, the driven element (7) being able to take two stable positions under the action of a bistable moving system connecting the driving element (15) to the driven element (7) such that each toggling between said two stable positions is due to an activation of the SMA actuating member, the latter being arranged together with the bistable moving system, with the resilient return member (25), with the driving element (15) and with the driven element (17) on a same side of the supporting body (1) in a substantially co- planar arrangement.
