In a system, the electrical circuit is closed if the door is shut. Which means so long as the door is closed, electricity can flow in one end of the signal to the other. But the world is opened, if someone opens the door, and energy can not move. An alarm is triggered by this.

In an open-circuit system, opening the door closes the circuit, therefore energy begins to flow. If the circuit is completed also in this method, The Alarm is activated.

- a battery powering a circuit

- a spring-driven metal switch included in a door frame
