At its core, a relay assembly integrates multiple relay components along with associated parts such as connectors, bases, and sometimes protective enclosures. A relay, which functions as an electrically operated switch, allows a low-powered signal to control a much higher power circuit. This capability makes relays invaluable in a range of applications from automotive systems to industrial automation.

    Components of Relay Assembly

    Relay Units： The primary component in any relay assembly is the relay itself. It consists of an electromagnetic coil, armature, springs, and contacts. When an electrical signal energizes the coil, it creates a magnetic field that pulls the armature, closing or opening the contacts and thus switching the connected circuit.
