A superconductive switching device includes an elongated gate which is circumferentially spirally overwound by a trigger. Both the gate and the trigger are superconductive, but the resistance of the trigger is much smaller than the normal resistance of the gate. Only a relatively small current is needed to cause the device to switch from a closed configuration where current flows through the switching device to a closed configuration where current flows to a load. Operation of the switching device is suitable for use with high frequencies and, with such frequencies, the switching device operates in a cyclical manner.
