Which stops the chairlift at top and bottom landings?

• A. Final Limit Switch
• B. Directional Limit Switches
• C. Wireless Controls
• D. Limit Switches

Answer: (B)

Directional limit switches control the stops at the top and bottom landings. They are set up so that each switch responds to the chair approaching a terminal in a specific direction, sending a stop signal to the drive when the car reaches the landing. Because there are separate switches for the up and down directions, the chairlift reliably halts at both ends regardless of which direction it came from. Final limit switches would only stop at the end of travel in one direction, and wireless controls don’t provide the immediate, hard-stop signaling needed at terminals. A generic limit switch lacks the direction-specific function required to stop at both ends.
