It stops supplying the electric power for the refrigerator when using the microwave oven, and starts supplying when finishing using the micro oven. It prevents the abrupt incsrease of the electricity consumption. It comprises 1st and 2nd door safety switches(21,23) detecting the opening of the oven door; an auxillary switch(24) detecting the wrong operation of the door safety switches(21,23); an AC power line(18), connected to the switches, getting connected to the microwave oven if the door gets open; a timer(25) connected between the power line(18) and the 2nd door safety switch(23); a switch(29) switching the power line between the microwave oven and the refrigerator.
