CA 2283012

In the microwave oven having a high voltage driving part with a high voltage transformer, a switching unit applies electric power to the high voltage driving part. In the switching unit, when switched on, an operational contact firstly comes in contact with a first contact coupled with a PTC thermistor and secondly with a second contact after a given time period, and a driving unit generates driving force and turns on/off the switching unit. Since the switching unit and driving unit may be simply installed to effectively eliminate the inrush current, assembly and work efficiencies are improved according to a simpler wiring process, and also, the total manufacturing cost for the microwave oven is reduced.
