A special switch is the relay, which contains 2 independent circuits: The primary, low power circuit which activates a magnetic switch through which a high power secondary circuit gets powered. In our case we can switch a 220 V circuit with a mere 3.3V signal.

To test this circuit we will however only switch a LED on a 5 V circuit with a signal from the primary 3.3V circuit.
