Relays use magnet wire coils to create electromagnetic force that opens or closes electrical circuits. These components support switching and control functions in appliances, vehicles, industrial equipment, electronics, HVAC systems, and power applications.

Because relays must respond accurately and consistently through repeated cycles, winding materials must support reliable conductivity, insulation integrity, and compact manufacturing. Essex Solutions provides magnet wire engineered to help manufacturers build relays with dependable switching performance and long-term durability.
