Explanation: A latching relay is a type of relay that can maintain a specific state without the need for continuous power applied to the coil. This type of relay has two stable states, set and reset, that can be activated by applying a momentary pulse of power to the coil. Once the desired state is reached, the relay will hold that state until a new pulse of power is applied. This makes them useful for maintaining a specific state even in the event of a power failure.
