Abstract
Abstract A zero insertion and withdrawal force receptacle for flat circuit bearing elements such as printed circuit boards. A slot is provided in the receptacle which is adapted to receive the element. At least one contact is normally biased to make physical and electrical contact with the element when it is in the slot and a cam is provided which is operable to cam the contact to a position where it does not contact the element when the element is either partially or fully inserted in the slot.
