Release time:2025-08-10 08:38:10
A 12-volt relay is an essential component in various electrical systems, commonly used for switching heavy-duty circuits with a low-power control signal. This electromagnetic device enables the control of larger loads with minimal power, providing an efficient and reliable solution in automotive, industrial, and home automation applications. In this article, we will explore how a 12V relay works, its different components, applications, and advantages.
What is a 12 Volt Relay?
A 12V relay is a type of electrical switch that uses a 12-volt DC signal to control the flow of current through a larger circuit. It functions based on the principle of electromagnetism, where a current flowing through a coil generates a magnetic field, activating a switch mechanism. When the relay is activated by the 12V signal, the internal contacts change position, either opening or closing the circuit to control the attached load.
Components of a 12 Volt Relay
Coil： The coil is the heart of the relay, where a 12V DC current passes through. The coil generates a magnetic field when energized, which either attracts or repels the armature to operate the switch.
