A temperature responsive device is described for use in operating a control element which, for example, controls the opening and closing of a valve or an electrical switch. The control element is moved by a trip rod which, in turn, is moved in response to the expansion and contraction of a plurality of aligned thermal expansion cells. Each of the expansion cells comprises an expander of a material having a high thermal expansion coefficient, and means restraining the expander against deformation other than in the direction in which the cells are aligned.
