Relays have been an essential component in the world of electronics for many years. A relay, in its simplest form, is an electrically operated switch. It enables low-power circuits to control high-power devices safely, making it an invaluable tool in many industries, especially in automotive and industrial automation. One of the most commonly used relay types is the 12V relay, which operates on a 12V power supply. In this article, we will explore the functionality, applications, and importance of the 12V relay in various fields.
What is a Relay 12V? A relay 12V is a type of electromagnetic switch that uses a 12V direct current (DC) to control a larger electrical load. It consists of a coil, an armature, contacts, and a spring. The relay operates by using a small current to create a magnetic field around the coil, which then attracts or repels the armature, moving the contacts. This allows for the control of a higher current to flow through a different circuit. The 12V relay is particularly popular because 12V is a common voltage in automotive and low-power systems. It is often used in applications where there is a need to switch high-current devices using a smaller control signal, such as a microcontroller or a switch.
