ABSTRACT:
A coil mounting arrangement includes a coil wound on a bobbin and in turn disposed about a core which is mounted to a frame. The frame includes a base portion and a leg portion which extends upwardly therefrom at a right angle. A support collar extends upwardly from the upper surface of the frame base portion and encircles a mounting opening which extends through the frame base portion. The core is inserted downwardly into press-fitted engagement with the frame within the support collar and mounting opening. Insertion continues until the height of the top of the core correlates directly with a position on the frame leg portion, such as the pivot axis of an armature. The underside of the frame base portion remains smooth.
