Joan,

There is a twisted wire cable with a loop on the end that connects to a
round object where the pin is sticking out.  This round object is on the
A-frame of your Airstream (or you should have one installed!) and the wire
cable goes from that round "switch" pin to the tow vehicle.  IF the tow
vehicle and the trailer separate in an emergency the tow vehicle will pull
the cable, which will pull the pin out of the round switch activating the
trailer's electric brakes to minimize damage to Mother Earth and any other
things unlucky enough to be in it's travel path.

If you can picture the pin on a grenade ;) and you pull the pin, what
happens?  Same thing here, with ONLY the pin pulling out of the "switch"
which activates the trailer brakes instead of blowing up the evidence.

Tom
