This is my alarm. As you can see everything is connected some how. There is a peace of string that is ached to the top, it has a peace of tape on the end. The tap is placed between my push to break switch. When the lead is opened the tape is removed. Letting the two wires attach, then the circuit is complete and the light goes off.
