Automation and Industrialization One of the primary factors driving the demand for relays is the increasing adoption of automation across various sectors. As industries move towards more automated systems to enhance productivity, relays have become indispensable. Relays are used in programmable logic controllers (PLCs), industrial robots, and automated assembly lines to control and monitor electrical circuits. Their reliability, versatility, and cost-effectiveness make them ideal components for these applications. Industries such as manufacturing, mining, and oil and gas are expected to drive significant growth in relay demand.
