Magnet Light Duty Plastic No/Nc/Com

light-duty plastic magnetic contact (or magnetic reed switch) is a security device designed to detect the opening or closing of doors, windows, or cabinets. It consists of two main parts—a magnet and a reed switch—housed in durable plastic (often ABS). These sensors are typically surface-mounted using screws or adhesive and are commonly used in low-voltage alarm systems, access control, and home automation.
