Abstract
A combined microwave and electric heating oven includes a gas sensor for detecting a completion of the cooking operation, and a timer for determining a cooking time period. A selection lever is slidably secured on a control panel for selecting a desired gas concentration value at which the cooking operation should be automatically terminated. First switches are disposed at both ends of the sliding course of the selection lever for placing the combined microwave and electric heating oven in a timer controlled operation mode instead of a gas sensor output controlled automatic cooking operation mode when the selection lever is located either end of the sliding course. A second switch is disposed at a preselected position in the sliding course for selecting the electric heating cooking when the selection lever is located at the preselected position.
