ABSTRACT:
A temperature regulating device is provided for electrical cooking appliances wherein the heat is provided by heating bodies, or elements, for plural heating zones. The device has a heat resistant bar or rod of high thermal expansion. The rod is enclosed within a tubular jacket formed of two tubes set end-to-end along the rod. The rod is spring mounted for moving an electrical contact of a switch to open and close the switch. The tubes have different coefficients of thermal expansion, the coefficient of the tube nearest the switch being the same as that of the rod, for providing a uniform switching characteristic over a wide range of operation of the heating elements.
