A relay is an electrical device that allows one circuit to control another, enabling switching of electrical signals without the need for direct physical contact. Low-power relays, specifically, are designed to operate with a small input current or voltage, making them ideal for applications where power conservation is critical. These relays are engineered to reduce energy consumption while maintaining high performance, which is especially important in devices that rely on battery power or have limited energy resources.

    Low-power relays typically feature an electromagnetic coil that, when energized, creates a magnetic field that activates a set of contacts, allowing current to flow in the controlled circuit. The main difference between low-power relays and traditional relays lies in their reduced power requirements and improved efficiency in operation.
