    • An assured grounding identifier includes a base unit connectable to an electrical cord, one or more indicators selectively adjustably mounted to the base unit and having colored regions, and a cover with one or more viewing windows aligned with the indicators. An assured grounding identifier includes a housing with a viewing window and a slot mountable around an electrical cord, an indicator having a plurality of colored regions disposed between the housing and the cord, and a tab extending from the indicator through the slot for positioning the indicator to align a selected colored region with the viewing window. An assured grounding identifier includes one or more indicators having a plurality of translucent color coded segments and an indicator light aligned with a viewing window to illuminate through the translucent color coded segments.
    • 有保证的接地标识符包括可连接到电线的基本单元,一个或多个可选择性地可调节地安装到基座单元并具有着色区域的指示器,以及具有与指示器对准的一个或多个观察窗口的盖。 有保证的接地标识符包括具有观察窗的壳体和可安装在电线周围的槽,指示器,其具有设置在壳体和绳索之间的多个着色区域,以及从指示器延伸穿过狭槽的突出部,用于定位指示器 将选定的彩色区域与观察窗口对齐。 有保证的接地标识符包括具有多个半透明颜色编码段的一个或多个指示符和与观察窗对齐的指示灯,以照亮半透明颜色编码段。

    • A light socket utilizing a photocell and three-way switch including a cylindrical housing having an upper end, a lower end, and a cylindrical side wall therebetween. The upper end is couplable with a power source. The lower end has a light receiving socket disposed therein. The light receiving socket is adapted for receiving a light bulb therein. A frustoconical shield is secured to the cylindrical housing. The shield has a narrow open upper end and a wide open lower end. The narrow open upper end is secured to the lower end of the cylindrical housing. The wide open lower end is dimensioned to prevent the light bulb from directing light upwardly toward the cylindrical housing. A light activated switch is disposed within the cylindrical side wall of the cylindrical housing. The light activated switch is in communication with the light receiving socket whereby detection of ambient light will allow the light receiving socket to power the light bulb positioned therein. A three-way switch is disposed within the cylindrical side wall of the cylindrical housing. The three-way switch is in communication with the light receiving socket and the light activated switch.
    • 一种使用光电管和三通开关的灯座,包括具有上端,下端和圆柱形侧壁的圆柱形壳体。 上端可与电源连接。 下端具有设置在其中的光接收插座。 光接收插座适于在其中容纳灯泡。 截头圆锥形外壳固定在圆柱形外壳上。 屏蔽罩有一个较窄的开口上端和一个宽敞的下端。 狭窄的敞开的上端固定到圆柱形壳体的下端。 宽敞的下端的尺寸被设计成防止灯泡朝向圆柱形壳体向上引导光。 光活化开关设置在圆柱形壳体的圆柱形侧壁内。 光激活的开关与光接收插座连通,由此环境光的检测将允许光接收插座为位于其中的灯泡供电。 三通开关设置在圆柱形壳体的圆柱形侧壁内。 三路开关与光接收插座和光启动开关通信。
