Abstract
A magnet and one or more magnetic field responsive switches, preferably Hall effect sensors, are respectively mounted in alignment on opposing edges of a two door refrigerator in one preferred embodiment. Movement out of alignment of either the magnet or switch generates a door ajar signal to activate visual and/or audio alarms. Embodiments employing mono-polar and bipolar Hall effect sensors are shown. A single door embodiment is shown with the magnet held in a fixed position opposite the sensor mounted on the door edge.
