41IT-2534 PIVOT INSERT METHOD AND ARTICLE The present invention relates to an electrical measuring instrument of the D'Arsonval type and more specifically to an improved low cost and small suspension system for the bobbin or armature assembly of such an instrument. Such improved suspension system includes the combination of a small light weight bobbin having thin gauge, surface insulated conductor wound on a light weight bobbin frame. Thin conducting strips are mounted to the frame above and below and these thin plates are provided with pins extending above and below respectively into jeweled pin pockets. Each pin is inserted at its blunt end through a strip in which it later resides by incorporating the pin in a punch, mounting the strip over an opening in a die beneath the punch and aligning the blunt end of the pin with the opening in the die.
