标题: Understanding Relay Lifespan: Factors, Types, and Maintenance Relays are essential components in electrical and electronic systems, acting as electrically operated switches that control circuits without direct human intervention. One of the most critical aspects of relay performance is its lifespan, commonly referred to as the “relay lifespan.” Understanding the factors that influence relay lifespan, the differences between mechanical and electrical longevity, and proper maintenance practices can significantly improve the reliability of systems that depend on these devices. Types of Relay Lifespan
