    • An appliance includes a leg for support upon a support surface, an interlock switch mechanically coupled to the leg and electrically coupled to control circuitry of the appliance, an anti-tip bracket having an aperture configured to receive a portion of the leg, and means for operating the interlock switch when the leg is properly positioned within the aperture. In one example, an actuator is coupled to the leg and is movable relative to the leg when the leg is positioned within the aperture. In another example, the interlock switch includes a first and second electrode, and selective electrical contact occurs between the first and second electrodes when the actuator is moved. In another example, a member projects from the appliance and the anti-tip is configured to receive a portion of the member. A method is also provided for preventing use of an appliance due to improper installation of the appliance.
    • 一种器具包括用于支撑在支撑表面上的支脚,机械耦合到支腿并电耦合到该器具的控制电路的互锁开关,具有构造成接收腿的一部分的孔的反尖端支架,以及用于 当腿部适当地定位在孔内时,操作互锁开关。 在一个示例中,致动器联接到腿部并且当腿部定位在孔内时可以相对于腿部移动。 在另一示例中,互锁开关包括第一和第二电极,并且当致动器移动时,在第一和第二电极之间发生选择性电接触。 在另一示例中,成员从设备投射并且反尖端被配置为接收该成员的一部分。 还提供了一种用于防止由于器具的不正确安装而使用器具的方法。
