relay schematic symbol

The product relay is an essential component in electrical and electronic circuits, serving as a switch or amplifier for controlling the flow of electrical current. Represented by a schematic symbol consisting of a coil and a switch, the relay operates by using an electromagnet to control the state of the switch. When an electrical current flows through the coil, it creates a magnetic field that either attracts or repels the switch, allowing it to open or close the circuit accordingly. Relays are commonly used in a variety of applications, such as industrial automation, automotive systems, and household appliances. They provide a reliable and efficient method for controlling high-power devices with low-power signals, enabling the safe and effective operation of various electrical systems. With their compact size, high reliability, and versatility, relays are an indispensable component in modern electronic and electrical designs.
