CJG-2 and CJG-4 operating mechanisms are specifically designed for 1/2-cell drawers used in GCS-type low-voltage draw-out switchgear. They enable the functions of opening, closing, testing, isolating, and locking, which are operated from the drawer panel. Additionally, a micro switch is mounted on the operating mechanism. It serves to electrically interlock the switching apparatus as the operating handle rotates within a 360° range.
