Abstract
A cooktop with a ceramic glass panel has a panel portion with a first indicia set for selection of a burner and a second indicia set for selection of a power level to the selected burner. Each set of indicia is associated with switches for input to a control circuit in response to manipulation by a user. In addition, each indicia set includes a display interactive with the manipulation of the other indicia set. Preferably, the control circuit includes a processor for responding only to a sequential manipulation of an indicia from the first set indicia set and a sequential manipulation of an indicia from the second set within a predetermined time period.
