Mechanical rack position indicator

A positional indicator system for a displaceable electrical component that is positioned within a chamber of a housing, the positional indicator system comprising:

• a bracket having a slot;
• a rotatable drum coupled to the bracket;
• a pin assembly including a pin body sized for linear displacement along the slot and coupled to the displaceable electrical component when the displaceable electrical component is linearly displaced within the chamber;
• a biasing element coupled to both the pin body and the rotatable drum, the biasing element including an arm portion, at least a portion of the arm portion of the biasing element being wound along the rotatable drum when the pin body is displaced along the slot in a first direction and to be unwound from the rotatable drum and linearly displaced as the pin body is displaced along the slot in a second direction;
• and
• a window providing visual access to a portion of a plurality of indicia that is positioned on a segment of the arm portion that is wound about the rotatable drum, the portion of the plurality of indicia visually accessible through the window providing a real-time indication of the relative position of the displaceable electrical component.

A system comprising:

• a switchgear housing having a front wall and at least one chamber, the front wall including an opening positioned to provide access to the chamber;
• a displaceable electrical component mounted to a moveable device, the moveable device configured to at least linearly displace the displaceable electrical component within the chamber;
• a positional indicator system including a pin assembly having a pin body coupled to the displaceable electrical component, the positional indicator system further including a rotatable drum, a slot, and a biasing element, the pin body being linearly displaced within the slot as the moveable device linearly displaces the displaceable electrical component, the pin body coupled to a second end of the biasing element, a first end of the biasing element coupled to the rotatable drum, a segment of the biasing element having a plurality of indicia, at least a portion of the segment of the biasing element being wound about the rotatable drum as the moveable device linearly displaces the displaceable electrical component in a first direction, at least a portion of the segment of the biasing element being unwound from the rotatable drum and linearly displaced as the moveable device linearly displaces the displaceable electrical component in a second direction;
• and
• a window in the switchgear housing providing visual access to a portion of a plurality of indicia that is positioned on at least a portion of the segment that is wound about the rotatable drum, the portion of the plurality of indicia visually accessible through the window providing a real-time indication of the relative position of the displaceable electrical component.
