Abstract
A shape memory actuator includes a shape memory actuator element for biasing an actuated member from an initial rest position to an operative position against the action of return spring means. Holding means are associated with the actuator element for holding the actuated member in its operative position even when the shape memory actuator element is deactivated. These holding means can be deactivated with a subsequent activation of the shape memory actuator element, allowing the actuated member to return to its rest position.
