They do actually because you can't use an ordinary light switch to switch
thousands of watts of lighting so usually there will be a solenoid activated
switching unit. Think giant relay, so you can use a sensible sized switch to
control the solenoid and they do make quite a loud clonking noise when they
switch, at least the old ones do anyway.
But computers DON'T make those stupid buzzzz beeeep beeerrr noises when
displaying something on the screen, stupid stupid idiotic film makers !!
