<p>PURPOSE: To perform setting of cooking time, selection of cooking menu and cooking start action/stop easily and rapidly by coaxially supporting first and second switching means, and constituting the first switching means in such a way as to act in the coaxial direction. CONSTITUTION: When a user depresses a first switching knob 67 of an operating switch member 10, a first shaft 38 connected to the knob 67 is pushed downward and connected to a momentary switch 14 of an action starting means mounted on a printed circuit board 12 so as to turn on the cycle switch 14. At this time, the shaft 38 is returned into the original position by the resilience of an resilient member 32. When the switch 14 is turned on, a low level signal is inputted to a connecting means. A control means therefore starts counting magnetron driving time. Cooking action is therefor performed only for the count time of a timer. In order to start cooking action by changing cooking time, the knob 67 is pressed after rotatory-operating the knob 67.</p> |
