What type of switch is operated by humans to control power flow to outputs?

The type of switch that is operated by humans to control power flow to outputs is referred to as a manual switch. Manual switches require a physical action from a user, such as flipping a lever, pressing a button, or turning a knob, to change the state of the circuit and either enable or disable the flow of electricity. This direct interaction allows operators to have control over the devices and systems they are managing, making manual switches integral to various applications in electrical and electronic systems.

On the other hand, automatic switches function based on pre-defined conditions or stimuli, meaning they operate without human intervention. Pneumatic switches are regulated by air pressure, while limit switches are designed to detect the presence or position of an object and facilitate control based on that detection. This makes them unsuitable when the requirement specifies human operation.
