Abstract
A connect/disconnect switch which is partially immersed in a cryogenic coolant includes colinearly arranged electrically conducting hollow cylinders separated by an electrically insulating as well as thermally insulating support member. An electrically conducting plug member is moveable within the cylinders with the cylinders being electrically connected to bus bars. During current flow operation, an electrical path is established between the hollow cylinders by means of the moveable plug whereas when a disconnect is desired, the moveable plug is removed from contacts with at least one of the cylinders thereby breaking the electrical as well as thermal path.
