摘要： A microwave oven includes a housing formed by relatively separable first and second panels. Electric switches are mounted on the first panel and are connected to respective wires of the power cord by the oven. Each switch includes a movable contact which moves away from a respective fixed contact when the panels are separated from one another, in order to automatically cut off the supply of electric power to the oven in the event that the worker forgets to unplug the power cord. When the panels are reconnected, the switches are automatically closed. Such automatic closing can be caused by magnetic force produced by magnets carried by the second panel. Alternatively, the automatic closing can be caused by screws carried by the second housing and which physically push respective movable contacts against their associated fixed contacts.
摘要翻译：微波炉包括由相对可分离的第一和第二面板形成的壳体。电开关安装在第一面板上，并通过烤箱连接到电源线的相应导线。每个开关包括当面板彼此分离时远离相应的固定触点移动的可动触头，以便在工作人员忘记拔掉电源线的情况下自动切断对烤箱的电力供应。当面板重新连接时，开关自动关闭。这种自动关闭可以由由第二面板承载的磁体产生的磁力引起。或者，自动关闭可以由第二壳体承载的螺钉引起，并且将相应的可移动触点物理推动抵靠其相关联的固定触点。
