What Is a Latching Relay

Basically, a latching relay is an electromechanical switch that generates a magnetic field as a result of a low input current. This is then used to open and close contacts in the relay. The contact is also able to hold its position even if the power source is disconnected. It can also be set up to operate in multiple circuits.

A latching relay can also save a significant amount of energy. This is especially useful in more complex lighting plants where there is a need to save power. Depending on the type of relay, it can save up to 5 kWh per year. In addition, it uses only about two watts of power, which is much less than a traditional relay.

Latching relays are typically used in applications where the switch needs to operate in multiple circuits, such as a lamp or lighting circuit. They are also used in many industrial applications, such as industrial sorting systems, commercial cooking equipment, and cleaning equipment. The relay's compact size and low energy consumption make it a convenient option for applications that require a small amount of current to be switched.

Latching relays are also known as bistable relays. They can be operated using a single coil or by using double coils. Both versions have the same basic circuit and operate in a similar fashion. They are suitable for small projects, as they are relatively cheap to manufacture. They are also safe to use and do not have the dangers associated with power-driven coils.
