    Are relays basically switches that are turned on by a certain minimum voltage? They are the electrical alternative to mechanical switches (or buttons)?..

    Yes you got it correct. As they are electrically controlled they make automated systems.

    Ah, simple. I wish most written explanations would just start with that line. :) Much appreciated the confirmation.
