ABSTRACT:
A key base or carrier permits a user to attach any off-the-shelf integrated circuit chip in dual in-line packages (DIP) thereto to form a switch-like device merely by bending the chip leads around the edges of the carrier. The carrier, with chip attached, is inserted into a housing between the rows of posts of a standard wire wrap socket and is rotated 90.degree. after insertion to wipe the bent chip leads on the socket posts to insure good electrical contact to the posts. The socket portion of the wire wrap socket assembly can then be used to plug in a ribbon cable, fitted with DIP headers (plugs) on each end, to transfer the electrical connections of the chip to the product circuit board. An independent switch, affixed to the wire wrap socket housing and actuated by the chip carrier, after all connections are made, signals the user's circuit that the chip is in place.
