A switching assembly of a heating appliance, for example, a microwave oven, wherein when the heating button is operated (depressed) with the door securely closed, the heating lever causes a projection to be engaged with a hook in the tip of the latch head and simultaneously causes the actuation of the heating switch. Thus the heating switch commonly functions as a heating switch and as a safety switch. By using such a mechanism, the heating switch which activates the heating operation commonly functions as a safety switch that activates itself when the door is securely closed. When the heating button is operated, a rotatable heating lever activates the heating switch, and simultaneously securely engages the latch heads with the front panel of the microwave oven. As a result, a switching assembly incorporating a highly reliable safety switch which can be securely locked by a simple mechanism is provided for a heating appliance.
