Fault-isolating apparatus and method for connecting circuitry
 A method and apparatus for electrically connecting circuitry on a printed circuit board having a plurality of circuit regions, with each circuit region having components operatively associated with input and output signal lines that are electrically isolated from the signal lines of adjacent circuit regions. The input and output signal lines of a particular circuit region are arranged in a closely spaced pattern aligned with a corresponding pattern of traces on an adjacent circuit region. A plurality of connector members are selectively attached to the printed circuit board to provide signal communication among the regions. Each connector member has closely spaced conductive bars which are exposed to contact the signal lines. The conductive bars have a length and a pitch such that the bars place parallel trace patterns in electrical communication when pressed in place. The connector members are multi-layered members having the conductive bars attached to a dielectric substrate and having an elastomeric material captured between a dielectric substrate and a metallic cap.
