ABSTRACT:
Adjustment of an electrical measuring instrument of the D'Arsonval type is achieved by rotation of an annular leaf spring contact mounted to rotate between an annular plate and a flanged eyelet extending through the plate and leaf spring. A conducting coil spring attached to the spring contact transmits rotary orientation of the spring contact to an armature assembly disposed for rotation against the return force of the coil spring in an magnetic field.
