Gravity: Magnetic Latching Relay Module

SKU: DFR0996

The magnetic latching relay is a new type using a permanent magnet for ON/OFF state, triggered by pulse signals and retaining state without power. It features low power, steady performance, long life, and low-temperature rise. DFRobot’s version, with a special driver chip, is small, easy to use—ideal for smart meters, lighting, sockets, switches, etc.
