ABSTRACT:
A current-reducing device (fuse or switch) is described comprising a foil mber of Al or Mg which is immersed in a fluid with which it will chemically react (such as H.sub.2 O or H.sub.2 O.sub.2) above a certain temperature. The foil member is an electrical conductor but becomes an electrical insulator as a result of the chemical reaction.
