Solid-state relay is a new type of non-contact switching device composed of solid-state electronic components. It uses the switching characteristics of electronic components (such as switching triodes, triacs and other semiconductor devices) to achieve non-contact and non-sparking.

Magnetic latching relay is a new type of relay developed in recent years, and it is also an automatic switch. Like other electromagnetic relays, it automatically switches on and off the circuit.

Magnetic latching relays offer compelling advantages for electric energy meters, including minimal power consumption, high reliability, and long operational life. Their unique characteristics make them indispensable components in modern smart metering systems. Oswell's continuous innovation in design and manufacturing ensures that their magnetic latching relays meet the evolving demands of the energy industry, providing utilities with robust, efficient solutions for advanced energy management and grid optimization.

Latching relays have revolutionized energy meter design by combining zero-power holding capability with robust switching performance. Their ability to enhance meter lifespan through reduced power consumption and mechanical durability makes them essential components in modern metering infrastructure. As smart grids evolve toward greater efficiency and functionality, latching relays will continue to play a pivotal role in enabling advanced features while maintaining the reliability expected from critical grid components.

Relays are essential electrical components that act as electrically operated switches, controlling the flow of current in a circuit by using a smaller current to activate a larger one. They play a crucial role in safety, automation, and power managementacross various household and industrial appliances. Below are some of the most common electrical devices that frequently use relays.
