1. Introduction to 12V Relays

12V relays are electronic devices that act as electrically operated switches. They are commonly used in various industries and applications where the control of electrical circuits is essential. Whether it's for automotive systems, industrial machinery, or home automation, 12V relays provide a reliable method to control electrical currents.

2. How Do 12V Relays Work?

A 12V relay consists of an electromagnet, a set of contacts, and a spring mechanism. When an electrical current passes through the coil of the electromagnet, it generates a magnetic field that attracts the contacts, closing the circuit. This allows the flow of current through the relay, enabling the control of larger electrical loads with a lower voltage control signal.

3. Automotive Applications of 12V Relays

In the automotive industry, 12V relays are widely used for various functions. They play a crucial role in controlling headlights, fog lights, fuel pumps, cooling fans, and other electrical components. By using relays, automotive systems can handle high currents without the need for heavy-duty switches, ensuring safety and reliability.
