ABSTRACT:
A new type of reed switch is described. The switch is comprised of a fixed lead and a flexible reed made of a magnetic substance which are contacting in a glass enclosure. Two magnet rods are coaxially arranged in the same direction with a superconducting film therebetween. When the surrounding temperature is descended below Tc of the superconducting film, a dipole moment is formed across the superconducting film and moves the reed away from the lead by the magnetic force thereof.
