a)Circuit 1A to 2A, which is a normally- closed (N.C.) switch, opens at 1025˚F and protects the ceran glass from heat damage.

b)Circuit 1B to 2B, which is a normally- open switch (N.O.) switch, closes and turns on the hot surface indicator lights if the temperature of the cooktop is greater than 150˚F. This switch will re- main closed until the ceran glass is warm enough to touch.
