I said a flip, flop, a flip, a flippedy flip flop a flip flip  don't stop the rocking to the bang-bang boogie said up jumps the boogie to the rhythm of the boogie the beat.

I like the one with two BJTs. It will work with MOSFETs too, or one of each.

Yeah. The one with the BJTs is the most practical one.

The relay one is practical too. For high current and/or voltage, you just need to pick suitable switches and relay. I like the 2-BJT one because I never understood it before. :)

Well done...👍

When using the relay, the load is connected in series to the relay's coil. Not good.

Why cant it go parallel to the coil?

Of cause, you could connect another realay, but when activated, current must run through the coil to keep it triggered. Else it will turn off again.

Why doesnt this work? http://everycircuit.com/circuit/5568341615050752

Because most of the current goes through the lamp, so the coil does not get enough to activate the relay. Connect lamp and coil in series and it will work.

Do you have a professional reference for this logic?

If you experience this irl then your drawing to much current than the source can provide. Try to keep voltage drop to 10% max, any more voltage drop and you will start seeing these problems.

Am I dumb, or didnt it work when I looked it up yesterday...?
