An electrical contact assembly that uses an elastomer strip for each row of individual contacts. Each contact comprises a rigid bottom pin and a flexible top pin with a pair of arms which extend over and slide along sloped surfaces of the bottom contact. The elastomer strip is located between rows of the bottom and top pins. A bottom socket housing is provided with grooves which receive each elastomer strip. A row of top pins is then placed over each elastomer strip, and through ducts in the bottom socket housing. Bottom pins are then snapped into place in between the pair of arms.

A stretchable wiring film includes: (A) a stretchable film made of, at least as a top surface of the stretchable film, a cured product of a stretchable film material containing a silicone polyurethane resin; and (B) a stretchable wiring. The top surface of the stretchable film has a repeated uneven pattern formed with depths of 0.1 μm to 5 mm and pitches of 0.1 μm to 10 mm. The stretchable wiring is formed on the top surface of the stretchable film where the repeated uneven pattern is formed.
