Claims7
A method for making tined electrical contacts from a continuous metal strip intermittently moving through a plurality of work stations, said method comprising:
- advancing said metal strip in an established first direction of travel to a first of said work stations, said first direction occupying a first plane;
- advancing a strip of contact material comprising a first layer of a base material and a second layer of a precious metal in an established second direction of travel to said first work station, said second direction of travel occupying a second plane substantially parallel to said first plane of travel of said metal strip;
- defining a preselected portion of said contact material at said first work station;
- positioning said preselected portion of said contact material at said first work station in alignment with a predetermined area on said metal strip;
- securing said preselected portion of said contact material to said predetermined area on said metal strip by attaching said layer of said base material to said predetermined area on said metal strip;
- separating said preselected portion of said contact material from the remainder of said strip of contact material;
- advancing said metal strip having said preselected portion of said contact material secured thereto to a second of said work stations;
- and
- cutting and forming said strip at said second work station to provide an electrical contact having at least one tine with a precious metal contacting area formed thereon.
