Claim:
1. In a contactor to be interposed between a contact load board and a device under test (DUT), the DUT including a plurality a plurality of contact pads, each contact pad being laterally arranged, a plurality of upper and lower pin pairs, the pairs having an outer surface and an overlapping inner mating surface capable of sliding longitudinally along the mating surface, an interposer comprising: a longitudinally compressible resilient non-electrically conductive membrane matrix having a plurality of spaced part apertures defining cross sectional areas and forming passages, each passage extending through said interposer, each passage sized to engage said pin pairs with horizontal elastomeric compression there-against, so that the pin pairs fill the cross section area of the aperture when sliding past each other thereby maintaining said mating surfaces mechanically and electrically engaged during sliding; said membrane matrix including a plurality of columns each having one of said apertures, said columns interconnected to adjacent columns by cross support members extending therebetween; and wherein said cross support members and columns together creates void spaces between columns thereby providing open expansion spaces between columns.
