Latching relays are not merely components but enablers of efficiency, accuracy, and reliability in energy metering. Their bistable operation ensures minimal power consumption, their inherent memory function guarantees accurate tariff application, and their robust design delivers long-term safety and cost savings. The integration of high-performance latching relays from specialized manufacturers like Oswell​ is, therefore, a critical design choice for developing next-generation metering devices that meet the evolving demands of modern energy management systems.
