摘要： A thermostat for a cooking utensil having a radiation heating body is constructed of an electrical switch actuated by a push rod. The rod extends away from the switch and expands in response to increasing temperature. The rod is held by spring loading within an outer tube of material, typically quartz or ceramic, of substantially lower coefficient of expansion than the rod. To permit adjustment of the thermostat during manufacture, a mating surface between a side wall of a housing of the switch and an end of the tube is constructed by forming an outward spherically shaped bulge in the side wall and an outward flaring of the end of the tube, thereby to permit relative motion between the housing and the tube without fracturing the end of the tube.
