CONSTRUCTION & ACTION: The load terminals are isolated from each other by a glass hermetic seal. "The plunger assembly" which includes a ceramic insulator, a magnetic sleeve and related parts, floats in a pool of mercury. When powered, the coil creates a magnetic field pulling the plunger assembly down into the mercury pool which displaces the mercury to move up making contact with the electrode, thereby closing the circuit between the line terminal on the top and the load terminal on the bottom which is connected to the stainless steel can.
