roller shutter magnetic door contact
roller shutter magnetic door contact is a security device that detects the opening and closing of a roller shutter door by using a magnet and a switch. It consists of two parts: a magnet mounted on the moving door and a reed switch mounted on the stationary frame. When the door is closed, the magnet is near the switch, keeping a circuit closed; when the door opens, the magnet moves away, opening the circuit and triggering an alarm.
