Abstract
Actuator apparatus having a drive element (26) which can tilt and/or pivot in a predetermined manner in response to electrical activation and which is formed such that it can be contacted by an output partner in order to transmit mechanical drive energy, wherein the drive element, as a connection element, is operatively connected to two expansion units (10, 12; 40, 42), which are formed by means of magnetic shape-memory alloy material, such that the connection element executes a tilting and/or pivoting movement in response to an expansion or contraction movement of one of the expansion units, expansion or contraction movement being produced by the electrical activation and also a magnetic field which is generated by said electrical activation.
