Mechanical lowering system component:

Explanation:
Mechanical lowering relies on direct physical linkages to move the load. Levers, cables, and cranks are classic elements that transmit force and motion without fluids or electricity. They let a pilot or operator apply motion to achieve lowering through simple mechanical means. The other options belong to non-mechanical systems: an electrical switch is a control device that starts or stops power but doesn’t transmit mechanical motion; a hydraulic pump powers fluid-operated actuators to move parts via pressurized fluid; a piston rod is a component of a hydraulic or pneumatic cylinder, not a pure mechanical lowering mechanism.
