push button to turn on/off arduino

Dear All,
i need a simple circuit to make a push button that completly shutdown arduino when pushed and turn it on when pushed again and so on.

Just buy a latching switch? But why would you want to do that?

Pololu makes a switch just for this purpose. Power Switch

They are easy to use and will perform the push on, push off action you are asking for... as well, the arduino can "shut itself off" with these switches.

it's called the power button to your power supply, ie. wallwart, battery pack, or just UNPLUG the USB cable...

This fellow (adolfhack) has a record of causing firestorms with spurious questions.
