The paper presents three persistent-current switches which were developed for superconducting coils on Maglev vehicles. Superconducting wire is used for the switches whose electric resistances are 100 ohms off-state (normal state), and current capacities are over 600A on-state (superconducting state) in a magnetic field of 1.5T. They are constructed of ten slender switch elements connected in parallel. Test results show that two of the switches can pass a current of 700A without quenching under conditions such as momentary spring vibrations or even if one of the ten switch elements is heated by the manganin wire heater.
