Abstract
The present invention provides an electrical contact comprising a first member having spring properties and a second member wrapped around at least a portion of the first member wherein the second member has a greater electrical conductivity than the first member. In one embodiment, a conductor is wrapped around at least a portion of a spring. In another embodiment, the spring is formed into a coil or helix with a wire wrapped around at least a portion of the helical spring. In one form of this embodiment, the spring has a plurality of turns and the wire is wrapped around at least two of the turns. In another form of this embodiment, the spring has a plurality of turns and the wire is wrapped around all of the turns. An interposer connector is also provided having a frame including a top surface and a bottom surface and a plurality of apertures arranged in a pattern and opening onto the top and bottom surfaces of the frame. A plurality of springs are provided with each spring having a conductor wrapped around at least a portion of the spring where the conductor has a greater electrical conductivity than the spring. One of the springs is positioned within each of the apertures so th…
