Relay assembly refers to the process of putting together the individual components of a relay to form a functional device capable of controlling an electrical circuit. A relay is essentially an electrically operated switch that uses an electromagnet to open or close contacts in a circuit. The assembly process involves carefully placing components such as the coil, contacts, spring, and housing together in a precise manner to ensure the device works as intended.

    Relays are used to control high-power devices with low-power signals, making them essential in applications where isolation between control and power circuits is necessary. The assembly of these relays involves intricate procedures, as each component must be correctly aligned and tested for optimal performance.
