ABSTRACT:
A flexible pointer is provided for use as a movable indicator, hand or arm on such devices as dial indicators, movable arms for electrical contacting devices, and the like. The pointer is comprised of a pair of strips of spring material joined at their upper ends and spread apart at their lower ends in a generally triangular shape, the outer free end being the indicating portion, while the wider, inner end is connected to a pivot or other movable support. The triangular configuration allows the pointer to bend due to rapid acceleration or overtravel and to return to its original shape without damage.
