A persistent current switch is presented. One embodiment of the persistent current switch includes a vacuum chamber. The persistent current switch also includes a cooling unit disposed within the vacuum chamber and configured to circulate a coolant between a first layer and a second layer of the cooling unit. Further, the persistent current switch includes a winding unit disposed on at least one of the first layer and the second layer of the cooling unit and configured to switch the persistent current switch from the first mode to the second mode when a temperature associated with the winding unit is below a threshold temperature. In addition, the persistent current switch includes a heating unit thermally coupled to the winding unit and configured to enhance the temperature of the winding unit above the threshold temperature to transition the persistent current switch from the second mode to the first mode. |
