Hi all
I've made a latching switch using a transistors but it's not working as it supposed, and i don't know why
When pressing the push button the led is lit but it's not latched since it turns off when depressing the switch
pls help why it's not latching the output voltage?

There is nothing wrong with the circuit, it should work OK.

Check your wiring and connections. If all seems OK then you could have a faulty transistor. With the button pressed in, check that there is almost zero voltage between the emitter and collector of each transistor.

Will you let us know the outcome?

The circuit seems to be fine. All you need to look for is your connections.
