A Magnetic latching relay is a new type of relay developed in recent years. Unlike normal relay, the ON or OFF state of magnetic latching relay depends on the action of a permanent magnet, and the state switching is triggered by a certain width of pulse electric signal. Once set or reset, the relay remains in the original state even when powered off.

• The magnetic latching relay features low power, steady performance, long service life, and low-temperature rise. It is perfect for applications requiring low power and high stability.
  
• This DFRobot magnetic latching relay based on a special driver chip is small and easy to use, and can be used to remake home appliances or lighting controls, like smart electricity meters/lighting/sockets/switches, and so on.
