Abstract
A microwave oven includes a pair of terminal members for connecting between a power source and a high voltage transformer, respectively. The terminal members are isolated electrically from each other by means of remote-locating, respectively. A conducting member is installed in the door, and both ends thereof are revealed on the one side of the door. The pair of terminal members contact with ends of the conducting member when the door is closed. Then, the supply of current supplied from electrical power to the high voltage transformer is controlled. Accordingly, the structure of the microwave oven is simplified. The AC/DC type microwave oven is capable of being prevented from encountering faulty switching operations according to large amounts of direct current when the DC input power source is used.
