Abstract
Methods of switching electrical current in the operation of an electrical load device such as an electrolytic cell having at least one anode and one cathode. At least one source of electrical current is connected to the anode and cathode at two spaced apart locations thereon. One method comprises the steps of disconnecting one of the locations on the anode and on the cathode from the source of electrical current, and connecting the disconnected locations of the anode and cathode directly together so that the path of current flow to and from the source of electrical current is limited to the anode and cathode. To reconnect the anode and cathode to the source of electrical current, the directly connected locations of the anode and cathode are unconnected from each other and reconnected to the source of electrical current. In addition, the invention includes the use of an anode or cathode, exclusive of the other, as means to heat an electrolytic cell.
