Abstract
A printed circuit board wedge assembly having a center section riveted to a printed circuit board. The center section is designed to allow the wedge operating shaft running longitudinally through the wedge assembly to be positioned into the center section opening with no obstructions. A biasing spring is placed through a slot and moved in place along grooves cut into the center section. The spring captivates the operating shaft assembly to the center section and enables all the wedge sections to be aligned.
