A Magnetic latching relay is a new type of relay. It features low power dissipation and is noiseless. Unlike other non-latching relays, the latching relay needs two digital pulse signals to switch the ON/OFF state.

This DFRobot Gravity: magnetic latching relay is compatible with the most popular microcontrollers such as esp32 / Arduino / Raspberry Pi. It can be used to remake home appliances or lighting controls, like smart electricity meters, lighting, sockets, switches, and so on.
