    • In a switching device having first and second conductor elements and an operating mechanism shiftable to and from a first position wherein the conductor elements are electrically connected to each other to establish a conductive path therebetween. The device includes a body of mercury, and a mercury wettable porous member between the mercury body and the first conductor element so that the mercury from the body may be forced through the porous body to establish the above-mentioned electrical connection. When the shiftable mechanism is shifted into the first position, the mercury is withdrawn from the first conductor element by the wettable porous member to disconnect the electrical circuit.
    • 在具有第一和第二导体元件的切换装置和可移动到第一位置的操作机构,其中导体元件彼此电连接以在它们之间建立导电路径。 该装置包括汞体,以及在汞体和第一导体元件之间的可汞化的多孔构件,使得来自身体的汞可能被迫通过多孔体以建立上述电连接。 当可移动机构移动到第一位置时,通过可润湿的多孔构件将汞从第一导体元件排出以断开电路。
