ABSTRACT:
A positive position indicator that is used on a variety of non-rotatable, cabinet slam-action pawl latches is disclosed. The indicator uses stored spring forces, stored in a thin, twin-leafed flat spring having a plurality of spring bends therein, to react against a latch keeper attached to the cabinet frame. The stored spring forces cause a spring tab to dislodge the latch pawl from an adjacent flat surface and move the latch housing and cabinet door away from the frame.
