Abstract
A tool is run into a liner that holds an electrical or hydraulic connection for a downhole tool which preferably is an electric submersible pump (ESP). It is capable of cleaning the electrical contacts, replacing them, isolating them from well fluid if no ESP or other downhole tool is to be present for a long time or switching from a main to a backup supply cable or hydraulic line among other downhole functions. The liner with the exterior cable or hydraulic line attached remains in position. Applications to other tools that obtain power or hydraulic pressure in a downhole wet connection are contemplated.
