What is the procedure for using the "Hand Throw" lever on a dual control switch?

The procedure for using the "Hand Throw" lever on a dual control switch involves moving the lever until the mechanism engages. This action is crucial because it ensures that the switch properly transitions from one position to another, allowing for safe and effective train operations. Engaging the mechanism means that the lever has been moved sufficiently to activate the switch's internal components, ensuring that it is fully thrown to either the "normal" or "reverse" position.

Holding the lever in a different manner or using it solely to maintain the position does not guarantee the mechanism's engagement. Quick pulling of the lever, while potentially appealing for speed, can compromise the precision needed in switch operations, leading to unsafe situations. Therefore, the correct approach is to carefully move the lever until it clicks or indicates engagement, ensuring the switch is fully set before proceeding.
