ABSTRACT:
A tool for extracting a printed circuit card from a holder the latter having top and bottom guide tracks and a rear wall having contacts engageable by terminal tabs on the card, comprised of a long tubular shaft having a mounting body rotatably connected on one end and a U-shaped linkage assembly pivotally mounted along the lower portion of the shaft. The mounting body includes a pair of magnets and a retainer clip disposed to mount on the top guide track and a pair of spring guides mounted below the magnets which stradle the circuit card to be extracted. The U-shaped linkage includes a notched area in each arm arranged to interlockingly engage similar notches on a circuit card stiffener or handle. A pulling force applied to the shaft extracts the card from the holder and its associated contacts.
