Abstract:
1. A high frequency heating apparatus in which a plurality of switches are switched with time differences by the motion of a plurality of tilting levers that are tilted in accordance with opening and closing operations of a door that exposes and closes an opening on a front side of the microwave oven, the high frequency heating apparatus comprising: a first switch whose contact portions are switched by elastically displacing a conductive contact piece in a switch case through a first cam formed at an inner end of a first tilting lever when said first tilting lever is tilted; a second switch whose contact portions are switched by elastically displacing another conductive contact piece in said switch case through a second cam formed at the inner end of said first tilting lever at timing different from the timing for switching the contact portions of said first switch; and a third switch switched through a third cam formed at the inner end of a second tilting lever when said second tilting lever is tilted, wherein a switch unit is formed by integrally incorporating said first tilting lever in said switch case.
