    • Switching apparatus for an electric iron control circuit includes a control switch assembly having a commutator switch and an on/off switch, including a pair of conductive members mounted on an insulating base. Each of the conductive members includes a plurality of conductive fingers interleaved so as to maintain electrical isolation between the conductive members. A rotary contact geared to the temperature control of an iron includes a contact member which alternately bridges and isolates the conductive fingers such that movement of the temperature select knob creates an interrupting signal between terminals connected to the conductive members. When the movable contact is in a predetermined position, a leaf contact is separated from a fixed contact so as to establish an on/off switch control. The base is pivotally mounted to the housing of the iron. A start switch includes a switch case having a pair of conductive resilient leaves normally electrically isolated and a switch button movably mounted in a switch case such that the movement of the switch button is operative to momentarily contact the two leaves to provide a start signal. The start switch is captured between the housing of the iron and a handle cover.
    • 电动铁控制电路的开关装置包括具有换向器开关和开/关开关的控制开关组件,该开关装置包括安装在绝缘基座上的一对导电构件。 每个导电构件包括交织的多个导电指状物,以便保持导电构件之间的电隔离。 与铁的温度控制相关的旋转接触器包括接触构件,其交替地桥接和隔离导电指状物,使得温度选择旋钮的移动在连接到导电构件的端子之间产生中断信号。 当可动触点处于预定位置时,叶片触点与固定触点分离,以便建立开/关开关控制。 基座可枢转地安装到铁的壳体上。 启动开关包括具有通常电隔离的一对导电弹性叶片的开关壳体和可移动地安装在开关壳体中的开关按钮,使得开关按钮的移动可操作以暂时接触两个叶片以提供启动信号。 起动开关被夹在铁的壳体和手柄盖之间。

    • An electric steam iron includes a plastic housing shell forming a hollow handle structure and a soleplate with steam generating means and ports for distribution of steam. A pump actuated by a handle button delivers water from a tank within the housing shell to the steam generating means. The iron is controlled by a low DC voltage electronic control including a printed circuit board disposed in the housing shell away from the soleplate and having means including a power resistor for reducing high AC line voltage to low DC supply to the circuit. The shell and hollow handle structure are open to the soleplate and the printed circuit board is directly exposed to heat from the power resistor. The power resistor is mounted directly on the soleplate between a pair of upstanding ribs on the soleplate and is cemented in thermally close coupling thereto by a heat transfer compound so that substantially all of the heat from the power resistor is conducted directly into the soleplate during use of the iron, thus preventing excessive heating of the printed circuit board and allowing the printed circuit board to be located within the housing shell.
    • 电蒸汽熨斗包括形成中空手柄结构的塑料壳体壳体和具有蒸汽发生装置和用于分配蒸汽的端口的底板。 由手柄按钮驱动的泵将水从壳体内的罐输送到蒸汽发生装置。 熨斗由低直流电压电子控制器控制,包括布置在壳体外壳中的印刷电路板,远离底板,并且具有包括用于将高AC线电压降低到电路的低DC电源的功率电阻器的装置。 外壳和中空手柄结构向底板开放,印刷电路板直接暴露于功率电阻器的热量。 功率电阻器直接安装在底板上的底板上的一对直立肋之间,并通过传热化合物与其热接合而胶合,使得来自功率电阻器的基本上所有的热量在使用期间直接传导到底板 的铁,从而防止印刷电路板的过度加热并允许印刷电路板位于壳体外壳内。
