S W I T C H ABSTRACT OF THE DISCLOSURE A switch is disclosed comprising two sets of rod-shaped fixed electrodes formed of a magnetic material and one cylindrical moving electrode formed of a permanent magnet, each set of the fixed electrodes being fixed to the respective end of a cylindrical vessel so that the ends of each set of the fixed electrodes face the ends of the other set of the fixed electrodes with the moving electrode capable of reciprocating between the ends of the two sets of fixed electrodes inside the cylindrical vessel. The moving electrode is comprised of at least one adhesive layer of a metal selected from the group con- sisting of silver, nickel, copper and alloys thereof on the surface of the permanent magnet, and at least one contact layer of a metal selected from the group consist- ing of rhodium, wolfram, rhenium, ruthenium and alloys thereof, silver-wolfram, gold-chromium on the adhesive layer of metal. At least the permanent magnet of the moving electrode and the adhesive layer of metal are thermally diffused with each other. - 1 -
