A general-purpose relay is an essential electrical component used widely across industries, offering versatility and reliability in controlling circuits. These devices act as electrical switches, allowing a low-power signal to control a high-power load. In today’s world, where automation and electronic systems play a crucial role in various sectors, general-purpose relays have become indispensable.

    At the core of their functionality, relays are designed to isolate different electrical circuits while transmitting signals between them. A general-purpose relay typically consists of an electromagnet, armature, contacts, and a spring. When an electrical current flows through the coil, it creates a magnetic field that moves the armature, closing or opening the contacts. This process allows the relay to control larger electrical loads with a much smaller input signal. This fundamental operation forms the basis of many applications in both industrial and consumer electronics.
