Hi im new to this stuff and i need ur help.
I have to draw a circuit where each one of the four engines is controled by one automatic switch (im not sure its called this way :p).The four engines are in a chain which means that in order for engine2 to start, engine1 must be already operating and so on. The engines are three phase.My problem is that each automatic switch has only one knife (? dunno hows called- its the thing that moves when the automatic switch gets voltage) which is the knife that helps the auto switch keep voltage after the "on" button is pressed (i think this knife is called bone).
Can someone help me? :blink:
Thnx for ur patience with my very scientific terms :p .

oh yes: each automatic switch will protect its engine thermally :p
