ABSTRACT:
A secure magnetic sensor has a first magnetic switch activatable by a first magnetic field and a second magnetic switch activatable by a second magnetic field which is stronger than the first magnetic field. The first magnetic switch is electrically connected in series to the second magnetic switch. In the default position, the first magnetic switch is in the open position whereas the second magnetic switch is in the closed position. When the secure magnetic sensor is normally activated, the first magnetic switch is activated to close. However, when the secure magnetic sensor is tampered by the addition of a supplemental magnet, this causes the second magnetic switch to be in an open position thereby sounding an alarm.
