2-coil latching type: Relays of this type have two coils: a set coil and a reset coil. The relays are set when a pulse is applied to the set coil and reset when a pulse is applied to the reset coil. * There are precautions for using latching relays. Please also refer to 4.
Dual Coil Latching General Purpose Relays are available at Mouser Electronics. Mouser offers inventory, pricing, & datasheets for Dual Coil Latching General Purpose Relays.
The latching relay has a small metal strip which can pivot between two terminals. The switch is magnetized, or attached to a small magnet. On either side of that magnet are small coils of wire called solenoids. The switch has an input and two outputs at the terminals.
Latching relays are 'bi-stable,' meaning they have two relaxed states. (These are also known as 'stay' relays.) When an electrical flow is turned off, the latching relay remains in the last state it was in. Latching relay is really a generic term that is used to describe the type of relay that maintains its position after the power is removed.
There are two kinds of latching relays: An electrically latched relay is a standard relay with one of its own contacts wired into its coil circuit. An external switch initially turns the relay on, then it is kept on by its own contact. An external reset switch interrupts power to the relay, which turns it off.

Grove - 2-Coil Latching Relay. This module is based on 2-Coil Latching Relay. Contrast to the ordinary relay, this latching relay does not need continuous power to keep the state, only a rising/falling pulse is needed to change the work state.
A latching relay, also called impulse, bistable, keep, or stay relay, or simply latch, maintains either contact position indefinitely without power applied to the coil.The advantage is that one coil consumes power only for an instant while the relay is being switched, and the relay contacts retain this setting across a power outage.
A latching relay can have one or two coils. In one-coil latching, the direction of current flow determines the position of the armature. In two-coil latching, the coil in which the current flows determines the position of the armature.
