ABSTRACT:
A contactor assembly including two pairs of electrical contactor carrying heads respectively disposed on opposite sides of a track for transporting packaged electronic devices having laterally extending connector legs or pads. One of the heads of each pair includes a stop projection. Electrical actuators and associated mechanical linkages are provided for sequentially moving the heads of each pair toward each other in steps from maximally separated positions to intermediately separated positions wherein the stop projections intrude into the path taken by devices moving along the track and thereby define a device test location, and then to minimally separated positions wherein the contactors of each head engage the connector legs or pads of a packaged device disposed in the test location.
