Answer & Explanation
The correct answer is Option C: C) pushing the switch lever arm while the winch is running.
Limit switches are safety devices designed to cut off power to the winch to prevent the davit arm from impacting the track stops. They are tested during the lowering operation by manually engaging the lever to ensure the power is immediately interrupted.
