Magnetic Latching Relays

A magnetic latching relay is a type of electrical relay that uses a magnetic field to maintain its position. Unlike a regular electromechanical relay, which uses an electric current to open and close its contacts, a magnetic latching relay uses a pulse of electric current to flip its internal mechanism between its two stable states. This allows the relay to "remember" its previous state, even after the current is removed. This can be useful in situations where power needs to be conserved, or where the relay needs to retain its state during a power outage.
