Abstract

The invention relates to an actuator, by means of which thermal energy is converted into mechanical work. The aim of the invention is to create a functional actuator on the basis of a shape-memory alloy. In order to achieve said aim, an actuator comprises an actuating element, which can be moved from an initial position to a final position with the aid of a drive device, which comprises a shape-memory alloy. Due to the movement to the final position, contact is established between the shape-memory alloy and a heat sink. Alternatively or additionally, due to the movement to the final position, the current flow by means of which the shape-memory alloy is heated is stopped or at least reduced using a switching element.
