An interposer configured for connecting offset arrays of signal pads on parallel surfaces. Contacts of the interposer have mating portions with multiple beams. One of the beams makes contact with a pad on a first of the surfaces and is deflected when the surfaces are pressed together with the interposer between them. A second of the beams is positioned so that the first beam presses into that second beam as the first beam deflects. The second beam may contact a central location on the first beam. An electrical path through the contact from a pad on the first surface to a pad on the second surface may be shorter when the first beam is pressed into the second beam than through the first beam alone. A shorter path may improve signal integrity. Moreover, the spring force of the contact may be set by the second beam.
