This paper describes experimental and theoretical considerations of the switching behavior of a magnetically controlled superconducting switch. The experimental superconducting switch used in the experiments is composed of a superconducting gate wire (NbZr/CuNi) and a superconducting field coil (NbTi/CuNi). The experimental circuit is that the switch is connected to a load resistor and a constant current source in parallel. The experimental results show: During the switching process, where the field current increases and decreases, the gate wire has two resistive states. In one state, the gate current is determined by the field current. In the other state, the gate wire may be in the flux-flow state.
