Low Voltage DC Relay： A Key Component in Modern Electrical Circuits

Relays are an essential component in electrical circuits, enabling control over high-power devices using low-power signals. Among the various types of relays, the Low Voltage DC Relay (LVDCR) plays a crucial role in controlling circuits with low-voltage direct current (DC) power. Widely used in automotive, industrial, and household applications, this type of relay is designed for efficient performance in low-voltage environments. In this article, we will explore the working principle, common applications, and benefits of Low Voltage DC Relays. What is a Low Voltage DC Relay? A Low Voltage DC Relay is an electrically operated switch used to control the flow of current in a low-voltage DC circuit. Its primary function is to use a low-power electrical signal to control higher-power electrical circuits. The relay consists of a coil, contacts, an armature, and a spring. When a current flows through the coil, it creates a magnetic field that moves the armature, causing the contacts to either open or close, thus controlling the power flow in the connected circuit.
