Relays are crucial components in various electrical circuits, acting as electromagnetic switches that control the flow of electricity. One of the most commonly used relays is the 12V relay, found in automotive, home automation, and industrial applications. In this article, we will explore the workings of a 12V relay, its key features, and the various applications it serves in modern electrical systems.
What is a 12V Relay?
A 12V relay is a type of relay designed to operate with a 12V DC input, which is a standard voltage used in many electronic and electrical systems, especially in vehicles and low-voltage control circuits. Relays are electromagnetic devices that use a low-voltage signal to switch a higher voltage or current. The fundamental components of a relay include a coil, contacts, and a moving armature.
When a 12V voltage is applied to the coil, it creates a magnetic field that activates the armature, causing it to either open or close the contacts. This allows a separate circuit, typically with a higher voltage or current, to be controlled by the low-power 12V input signal.
