You should NOT need to touch the manual trailer brake switch unless you need to make emergency stop. If the brakes are set correctly, you'll feel them kicking in when you step on the brake peddle of the vehicle your driving. You should feel a slight "tug" when you brake the vehicle you're driving. The trailer brakes will then release an instant after you take your foot off your brake peddle. In all the years I've been towing trailers, I've NEVER had to even touch the manual brake controller switch.
