An electrical connector system which may be used to prototype electrical circuits utilizing standard integrated circuit packages on a perforated circuit board. A plurality of spring contact elements having oppositely directed resilient jaws are carried in an insulating housing. An insulating contact retainer, carrying a plurality of spring compression reserve wire contact elements, is placed on the opposite surface of the perforated circuit board from the connector housing, with a tail of each contact element extending through a perforation in the circuit board into one set of jaws of a spring contact element aligned with the perforation. The contact leads of an integrated circuit package are similarly inserted into the oppositely directed, spring contact element jaws. Electrical contact to the contact leads of the integrated circuit package is then made through the spring contact elements and the wire contact elements to wires connected by the wire contact elements.
