Abstract

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 When the shiftable mechanism is shifted into the first position, the mercury is withdrawn from the first conductor element by the wettable porous member to disconnect the electrical circuit.
