To improve the safety of the interlocking switch circuit comprising a monitor switch, primary switch and secondary switch which are on/off by the opening and closing of the electronic range door in order to control the operation/nonoperation of the microwave generation device of the electronic range. The above switches are taken as relay contact points respectively, so as to be able to operate the on/off of each switch from outside. By this, the detection jig is decreased, the detection time period is also shortened and a cause of the safety decreases due to the increase of the efficiency removed. In addition, the switch which turns the on/off of the microwave generation device of the electronic range is adapted to increase the safety of the interlocking switch circuit by being arranged independently.
