ABSTRACT:
A tilt switch assembly (100) includes a hall-effect device (102) for determining if a magnet (110) which is placed within a housing (112) has tilted a predetermined amount causing the hall-effect device to actuate. In another embodiment of the invention (300), a movable magnetic filed concentrator (306) which moves in response to switch assembly (300) being tilted causes a tilt condition signal to be generated when the switch assembly (300) is tilted a predetermined amount. In still another embodiment of the present invention, a magnet (502) is stored within a cavity area which allows for the magnet to tilt when the switch assembly (500) is tilted a predetermined amount. Once the magnet (502) becomes tilted, a tilt condition signal is generated.
