A pair of cams judiciously positioned at each end of a side-entry edge-card connector is actuated by the card, which in turn actuates the spring contacts of the connector. The diagrammatic illustrations in Figs 1 and 2 show the principles of the construction and operation of the improved arrangement. A pair of cams 1 and 3 is provided, the cams being located at the opposite end of a ZIF (zero insertion force) connector, the details of which are not shown for the sake of clarity. The cams pivot about points 2 and 4 and have the configurations shown. Element 5 is a driving piece or cam which is coupled to the ZIF springs to operate the springs between their contacting and non- contacting positions. Fig. 1 shows the operation taking place during the insertion of a card 7 in the direction from left to right.
