Latching Relay Module

Latching Relay Module

In electronics, a device is said to be a latching device if it maintains any particular fixed state even after removal of the input signal. The same also applies for electronic/electromechanical relays. Basically the electromechanical relays that are used today are of two types:

1. Non-Latching Relay : These relays are most widely used where energy consumption is basically not an issue.This type relay(s) comes back to its original state once the input signal is removed.

2. Latching Relay : These relays are mostly used in automobiles and are rarely used for basic prototyping needs.

Most of the relays which we use today are monostable relays, that means it has only one stable state and so it is called non-latching relays. You must have heard about N.O (Normally Open) and N.C (Normally Closed) terminals of a basic electromechanical relay. However these terminals which are present over the relay show that the electronic relay which we are using has only one stable state.

In this instructable I will show you how to use a non-latching relay as a latching bistable relay by designing a simple electronic module which is powered by an external power source. One can use this module for many other projects and it’s intentionally made portable so that one can easily carry it around. Moreover it has many other useful features which provides it many additional functionalities.
