摘要： A thermostatic control valve has an expansion composition held in a cavity thereof. The composition contains electrical conductor particles dispersed throughout an electrical isolator. The particles conduct electrical current through the isolator when the electrical isolator has a volumetric size that is less than a predetermined expanded volume. When the isolator expands to the predetermined expanded volume, the distance between the particles is increased to the extend that the electrical current cannot be conducted.
