Abstract: A contactor apparatus for electrically interconnecting a lead of an electrical device to a conductive area on a board. The contactor apparatus includes a housing having a slot. It also includes a probe disposed within the slot, the probe having a fulcrum for engaging the conductive area on the board and an arm for engaging the lead of the electrical device. The contactor apparatus further includes an elastomeric element disposed transverse the slot and engaging the probe, wherein as the lead of the electrical device engages the arm, the probe pivots within the slot about said fulcrum, the fulcrum rocking on the conductive area of the board. The contactor apparatus may also include a manual nest for holding the electrical device. The manual nest has a handler for securing the electrical device within the housing, the handler having an open window for accessing the lead of the electrical device when the manual nest is inserted into the housing.
