A relay is an electrical switch that allows a low-power signal to control a higher-power circuit. It acts as an intermediary, ensuring that a small electrical current can trigger a larger one, which is especially useful in situations where direct control is not possible. Relays are widely used in applications such as automation systems, motor controls, and power distribution networks.

    However, as technology continues to evolve, the components that power these systems also need to adapt. Aging relays can become inefficient, unreliable, or even dangerous if left unchecked. Over time, they may lose their sensitivity, experience wear and tear, or become outdated due to technological advancements. This is where relay upgrades come into play. Upgrading relays ensures that systems continue to operate efficiently, with improved functionality, faster response times, and enhanced safety.
