What are Spring or Dual Control Switches considered when operated by hand?

Spring or Dual Control Switches are considered hand-operated switches when they are operated manually. The term "hand-operated" refers to the operation of these switches using physical manual control, which is typical when they are traversed without the assistance of an electric motor.

While these switches may also have electric control capabilities, their primary function in hand operation highlights the user’s direct involvement in controlling the switch mechanism. This means that when an individual physically moves the switch to change its position, it is classified as a hand-operated switch.

The distinction is important because it ensures operators understand how to safely and effectively manage the switch in various situations, especially in a switching yard or during manual operations.
