标题: Understanding the 12V Relay: Key Features and Applications

A 12V relay is an essential electronic component widely used in various industries, from automotive systems to home appliances and industrial automation. Its primary purpose is to allow a low-power control circuit to operate a high-power load circuit. Relays, in general, are electromechanical switches that enable electrical isolation between the control side and the load side of a circuit. In this article, we will explore the key features, working principle, types, and diverse applications of the 12V relay. What is a 12V Relay? A 12V relay is a type of relay that operates on a 12-volt direct current (DC) signal. It consists of an electromagnet coil, a set of movable contacts (normally open or normally closed), and a spring mechanism that holds the contacts in place. When a 12V DC signal is applied to the coil, it generates a magnetic field that pulls the contacts together (in the case of a normally open relay) or pushes them apart (in the case of a normally closed relay). This allows the relay to either complete or break a circuit on the load side, enabling the control of high-voltage devices with a low-voltage control signal.
