ABSTRACT:
A contact device for enhancing the conductance of an electrical connection which includes two conductors (21and23) in contact with each other essentially including an interposed conductive element arranged between the two contact surfaces (22and24) of the two conductors (21and23) of the connection. The interposed conductive element is made of electrically conductive foam (10) which includes one or more materials with high porosity and deformability so as to reduce the electrical resistance of the connection.
