Abstract
A combined temperature responsive valve construction and an electrical switch construction wherein the valve construction has a thermally responsive device of the piston and cylinder type operating a movable valve member that is engaged by the piston of the device and operates an actuator of the switch construction, the valve member comprising an axially movable valve stem having opposed ends one of which is engaged by the piston of the device and the other of which operates the actuator. A coiled compression spring has one of the opposed ends thereof engaging a spring retaining part of the other end of the valve stem in a retained manner and the other opposed end thereof engaging the actuator whereby axial movement of the valve stem toward the actuator will tend to compress the spring therebetween.
