Which statement best describes a manual switch?

• A. Operated automatically by a sensor
• B. Controlled remotely via network
• C. Lever operated, special purpose
• D. Activated by a microcontroller

Answer: (C)

Manual switches are operated by hand rather than automatically. A lever-operated design is a classic example of that hand-driven actuation, where you physically move the lever to change the circuit state. The phrase "special purpose" here suggests the device is built for a particular task or machine, often with a robust, tactile control suitable for manual use. Other options describe controls that don’t rely on direct hand action: automatic by a sensor, remote via network, or triggered by a microcontroller. Those involve automatic or electronic control rather than deliberate human actuation, which is why they don’t describe a manual switch.
