Magnetic contacts
)
Magnetic contacts are important security sensors. They consist of a small magnet and a reed switch, mounted on a door or window frame. When the door is closed, the magnet attracts the reed switch, keeping it closed. When the door is opened, the magnet moves away, triggering the reed switch and sending an alarm signal to the control panel. Magnetic contacts are widely used in homes, offices, and access control systems to detect unauthorized entry.
