Abstract

A simple and cost-effective method is provided, according to which a positive temperature component (PTC) element directly controls the element made of a shape memory alloy. A simple and cost effective device for performing the method has a PTC element series-connected upstream from the element made of a shape memory alloy, in the electric circuit for the element made of a shape memory alloy.
