Final answer:
The advantage of using low voltage input devices such as switches, dimmers, and sensors as opposed to line voltage devices lies in safety and energy efficiency.
Step-by-step explanation:
The advantage of using low voltage input devices such as switches, dimmers, and sensors as opposed to devices that run off of line voltage is primarily related to safety and energy efficiency.
Low voltage devices typically operate at 12V or 24V, which is much lower than the 120V or 240V used in line voltage devices. This reduces the risk of electric shock and makes them safer to handle and install.
Additionally, low voltage devices are often more energy efficient because they require less power to operate, resulting in lower electricity consumption and costs.
