A jitter-free, repetitive opening switch made of YBa2Cu 3O7-x high-temperature superconductor is demonstrated. The switch conducts electrical current at no loss when it is superconducting. A pulse or pulse train of magnetic field on the order of 100 G causes the transition of the switch from the superconducting state to the resistive normal state and forces current to flow through a load resistor that is connected in parallel with the switch. Repetitive operation of this switch at rep rates higher than 1 kHz has been demonstrated.
