A device used to manually align a powered switch.

• A. Strobe
• B. General Notice
• C. Switch Crank
• D. Switch

Answer: (C)

The main idea here is that a manual method is needed to move or verify the position of a powered switch. A switch crank is specifically designed as a hand-operated device that attaches to the switch mechanism and provides the leverage needed to rotate the switch points into the desired alignment. This lets a worker physically set the route when the motor drive isn’t being used or when a manual check is required, ensuring the switch blades line up correctly with the rails.

Strobe, general notice, and the switch itself aren’t devices suited for manually aligning the powered switch. A strobe is a lighting or timing device, a general notice is a document or alert, and a switch refers to the turnout itself rather than the manual tool used to adjust it.
