Which of the following is an example of a manually operated component in a control circuit?

A manually operated component in a control circuit is designed to be activated by human interaction, typically involving a physical action to control the flow of electricity.

In this scenario, both a single-pole toggle switch and a pushbutton switch require direct human operation to function. A single-pole toggle switch allows the user to turn a circuit on or off by flipping the lever, while a pushbutton switch is activated when the user presses it. Both of these devices give the operator direct control over the electrical circuit, which is the hallmark of manually operated components.

On the other hand, a float switch is an example of an automatically operated component. It activates based on the level of liquid in a tank rather than through human intervention. Therefore, it does not fit the definition of a manually operated component in the context of control circuits.
