Relay assembly is a crucial aspect of modern electronic and electrical systems, serving as an integral component for controlling high-voltage circuits, automating processes, and e At its core, a relay is an electromagnetic switch that utilizes an electromagnet to mechanically operate a switching mechanism. When an electrical current passes through the coil of the relay, it generates a magnetic field, drawing a lever or armature toward it, which closes or opens the electrical contacts in the circuit. This allows the relay to control a high-power circuit using a low-power signal, providing effective isolation between the control circuit and the operational circuit. The Structure of Relay Assembly A typical relay assembly consists of several key components： Coil： The coil is the part of the relay where the control signal is applied. When energized, it creates a magnetic field.
