In the world of electronics and electrical engineering, relays play a crucial role in controlling circuits with low-power signals while switching high-power devices. One of the most widely used types of relays is the 12-volt relay, which operates on a 12V DC (direct current) supply. The versatility, reliability, and affordability of 12-volt relays make them an essential component in various applications, from automotive systems to home automation. In this article, we’ll dive into the working principles of 12-volt relays and highlight the excellent products offered by Meishuo, a company known for its high-quality relay solutions.
What is a 12 Volt Relay?
A relay is an electrically operated switch that allows a low-voltage signal to control a higher voltage circuit. A 12-volt relay typically uses a 12V DC input to activate its internal switch, which in turn can control much higher voltage devices, usually up to 120V AC or more. The relay consists of an electromagnet, a movable armature, contacts, and a spring. When the 12V power is applied to the electromagnet, it generates a magnetic field, pulling the armature and closing the contacts. This allows electrical current to flow through the circuit, powering connected devices. Once the power is removed, the spring pushes the armature back, opening the contacts and breaking the circuit.
