  • Multiple resistance element assembly and method of making same
    Patent number: 4339743
    Abstract: A multiple resistance element assembly having two parts, an insulator base and a multiple resistance element having expanded metal resistance members. The ends of the expanded metal resistance members are serially connected by contiguous non-expanded metal sections joining the ends of adjacent members. Tabs formed from contiguous non-expanded metal are bent normal to the plane of the resistance members and are inserted into mating slots formed in the base, and lock the multiple resistance element to the base.
