What is the purpose of a latching relay?
A latching relay is a two-position electrically actuated switch that maintains either contact position indefinitely without any power being sent to the coil and is a perfect choice to reduce the power consumption of a system.
How does a latching circuit work?
In Electronics, Latch Circuit is a circuit which locks its output, when a momentarily input trigger signal is applied, and retains that state, even after the input signal is removed. This State will remain indefinitely until the power is reset or some external signal is applied.
What is a latched relay?
How do you reset a latching relay?
Resetting is very simple. The coil circuit needs to be opened and shortened to the coils ground potential. The capacitor will be discharged through the coil and drives a current pulse with opposite polarity through the coil, that resets the relay (Figure 4).
How must a latching relay be reset?
How does a latching switch work?
A latching switch, when wired normally open, can be pressed once to close the electrical circuit and cause something to switch on. When the pressure is removed from a latching switch it remains on until the user switches it off again by pressing it once to re-open the circuit causing a break in the electrical current.

What is a latching relay used for?
Latching relay is used to turn ON the output and maintain its state with a small duration or impluse signal. It will maintain this state untill the next opposite impulse or small duration signal is applied to it. Latching relays are used in case of motor starters where we don’t want to press the start button continously.
What type of relay for 12 volt?
Relays are used for isolating a low voltage circuit from high voltage circuit.
