Opening the door or window moves the magnet away, causing the switch contact to open and trigger an alarm.

It consists of a reed switch and a magnet. Installation Environment: Suitable for use in industrial equipment and household appliances. Avoid impact during installation to prevent damage to internal components. The magnet and the switch must be aligned parallel to each other for correct positioning.
