Zusammenfassung:	A range burner surface heater system includes an input selector, a control, a surface heating unit, and a pair of low cost relay switches. The input selector is connected to the control, and the switches are responsive to the control. The surface heating unit is located between the low cost relay switches, with each relay switch connected to a separate power line. The relay switches are alternately opened and closed to energize the surface heating unit singly and in combination. At lower power levels, the switches are operated at current levels of one half the rated current of each switch to extend the life of the switches.
