The emergency button switch is a switch that is activated when an emergency is needed. This device uses a tact switch that is easy to operate and easy to carry. When the emergency button switch is pressed, the IO port of the module (the 19th pin of U1) detects a low level, and when the emergency button switch is released, the IO port of the module KEY1 (the 19th leg of U1) detects a high level.
