From the above link-


'An active device is any type of circuit component with the ability to electrically control electron flow (electricity controlling electricity). In order for a circuit to be properly called electronic, it must contain at least one active device.'

I though an electromagnet in a relay did this, although as its electromechanical I think its a half way house between electrical and electronic.
