Abstract
A plurality of shuttle means receive untested devices from a feed track and position the devices in electrical contact with a contactor for testing. The shuttle means also discard tested devices via an exit track. Each shuttle means has a test track and a by-pass track. When all the shuttle means are in a load position, each track acts as a segment in a continuous track between the feed track and the exit track. When all the shuttle means are in a test position, each by-pass track acts as a segment in a continuous track between the feed track and the exit track. As long as each shuttle is either in its load position or test position, there is a continuous track between the feed track and the exit track, the segments of the track comprising either by-pass tracks, test tracks or any combination thereof. Defective devices can be pulled from test and discarded while others are undergoing testing.
