Which type of device can utilize a switching relay?

• A. Only low-voltage devices
• B. Only high-voltage devices
• C. Either low or line-voltage devices
• D. Only manual devices

Answer: (C)

A switching relay is designed to control circuit operations based on input from another device, allowing it to manage the flow of electrical current. This means it can handle a variety of voltages depending on its specific design and application. The correct answer highlights that a switching relay can be utilized with either low or line-voltage devices. Low-voltage devices typically operate at lower currents and are used in applications such as control panels and lighting, while line-voltage devices can be found in standard household applications, where they typically operate at higher voltages. This versatility makes switching relays an essential component in many electrical and HVAC systems, as they can efficiently manage loads for both types of voltage, increasing their usefulness in various installations, whether for powering or switching large appliances or lighting circuits.
