Other switchgear from TV and movie shows:
Don't know about Jurassic Park, but I vaguely remember an eposide of the orginal Star Trek TV show where someone at some mental facility shut off the power to the building, and later turns it back on. Though Star Trek was supposed to be 200+ years in the future, they had a tight production budget and likely just used an existing electrical closet for the scenes above. Something the average person doesn't usually see, but obviously recognizable as a power switch. But not looking like something from Frankenstein movies.
