<p>A superconductor switch includes a superconductor module and an actuator. The superconductor module includes first and second superconductor wires non-inductively wound in a hollow shape in a state where ends of the first and second superconductor wires are connected to a first terminal, and the first and second superconductor wires have different critical characteristics. The actuator is configured to mechanically response to a magnetic field induced at a hollow part of the superconductor module for being switched between a second terminal and the other ends of the first and second superconductor wires. If an over-current is applied to the first terminal, a magnetic field is induced at the hollow part of the superconductor module.</p>
