A 12V DC relay is an essential component in modern electrical systems, enabling the control of high-power devices using a low-power signal. Widely used in automotive, industrial, and household applications, relays play a crucial role in safely switching electrical circuits. In this article, we will explore the working principle, components, types, and common applications of 12V DC relays.
What is a 12V DC Relay? A 12V DC relay is an electromechanical switch that is activated by applying a 12V direct current (DC) voltage to its coil. The relay consists of several key parts, including the coil, armature, contacts, and spring. When current flows through the coil, it generates a magnetic field that pulls or pushes the armature to make or break a connection between the contacts. This allows the relay to control the flow of electrical power to other circuits, making it ideal for situations where a low-voltage control signal is needed to switch high-voltage or high-current devices.
