Abstract
An actuator includes a sliding body moveable along a guide between a rest position and a retracted position, a spring resting on a support body and acting to exert a bias force urging the sliding body to the rest position, and a SMA wire having opposite ends being mechanically and electrically connected to a respective one of two stationary contacts and forming a loop between the opposite ends which is connected to the sliding body, wherein the SMA wire is arranged to, when activated by electric energy supply, pull the sliding body away from the rest position to the retracted position, wherein the guide is fixed to a first end portion, the support body is fixed to an intermediate portion, and a contact holding body, in which the two contacts are incorporated, is fixed to a second end portion of a mounting bar.
