PROBLEM TO BE SOLVED: To enable to produce a contact switch without effort or expense, and ensure a high operating reliability and safety. SOLUTION: The layout of the contact switch for a hob, having some hot plates is described. Separated selective switches for the hot plates are installed in respective cases, and by this, outputs can be selected in the respective cases. There is also a single common contact switch for decreasing the outputs for all the hot plates. According to the operating instruction, only the output of the selected hot plate is revised or decreased, when the common output control switch is operated. The output of the hot plate is increased, by shortly operating the selection button as the selection, and by revising operation of the selection button as the increase. Thus, this device functions as an output increasing switch. It is clear that this function can be replaced.
