Abstract
A power operated tool (20) functions to cut and collect a multitude of precious metal contacts (11,11) from wire spring relays (10). The tool (20) includes a pair of jaws (31,32) that in the open position fit over several rows of contacts (11,11). When the tool (20) is energized, the jaws (31,32) are snapped shut thereby severing the contacts (11,11) from the relays (28). The jaws (31,32) in the closed engaged position define a closed chamber (41) having a port (44) for attachment to a vacuum source for sucking the severed contacts (11,11) into a collection vessel. The jaws (31,32) reopen following collection and the tool (20) is ready to cut the next set of spring contacts (11,11).
