It’s a common phenomenon that people rush to get into the subway during rush hour in most of big cities. If an emergency issue occurred, in particularly the doors closing while people are still running inside. It’s quite possible that a person’s luggage or even the person himselfcould get stuck in the door. To solve this problem, a security switch is designed to improve the signal to the train driver, officers and outlook personal, for a quick response to open the doors.
