A compliant electrical contact and an assembly employing a plurality of the contacts that provides an interface between two electrical devices. The contact has a convoluted spring with convolutions and a contact point at each end. In one contact embodiment, the convolutions have appendages which electrically short adjacent convolutions throughout a significant portion of the compression range of the contact. An appendage may be a single finger that extends from one convolution toward the adjacent convolution, a pair of opposed fingers that extend toward each other from adjacent convolutions, or machined edges on adjacent convolutions. In some configurations, the fingers or a surface on the appendage or fingers are at a skew angle to the direction of compression.
