Simple Latching Circuit Diagram. Three Push ON Push OFF Latching Circuits. While this circuit works and looks really simple it doesnt quite meet the requirements for.
The latching ability of the S-R latch circuit holds the output state steady during the mechanical switchs bouncing action allowing a clean output transition to take place. The circuit can be made to change state by applying a signal in this case by pushing a buttonHere I will show you three different ways to m. If desired you can connect the output 9V at the top right to additional required circuits.
Note that A0 and D0connect to the micro-controller and the 5V and ground to the right of the diagram.
A transistor latch is a circuit which latches ON with a permanent high output in response to a momentary input high signal and continues to stay in this position as long as its in the powered condition regardless of the input signal. The diagram above shows how such a relay can be used to make a latching relay circuit. In this post we learn how to make a simple transistor latch circuit using just two BJTs and a few resistors. So the first 22KO resistor that goes into the base of the BC547 is used to limit current that goes to the BC547.
