What the emergency breakaway switch does, is to apply an electrical current from your trailers battery to the electric brakes on your trailer.................in the event that (god-forbid) your trailer comes detached from your tow vehicle. When the trailers comes loose, the cable hooked to the pin on the breakaway switch is supposed to be pulled out, since the other end of the cable should be still hooked to your TV. By applying the trailers brakes, the switch keeps your trailer from rolling and brakes it quickly to stop it.
When you are normally hooked to your tow vehicle, your brake controller in your vehicle is what supplies all the electrical power to your trailers brakes to stop it.
Anytime you pull the pin, you are applying your trailers brakes from your batteries power. This is probably hard on the brakes if done for any extended length of time, as well as the breakaway switch itself. I have no idea how long the switch is rated for, to have a charge running thru it. I've never heard of anyone pulling the plug but for a short time to test it or such.
