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.

  1. Remaking home appliances
  2. Lighting controls
  3. Smart electricity meters
  4. Smart lighting
  5. Smart sockets
  6. Smart switches


  1. Low power consumption, 2.6mw-3.65mw
  2. Noiseless
  3. Trigger Pulse Width: 2ms
