ABSTRACT:
A position sensitive alarm is mounted to an item of personal property to be protected so that if the property is moved, an audible alarm is produced. The alarm includes a housing in which a battery, a buzzer and a position-sensitive switch are mounted therein. An aperture is cut in the housing so that the sound produced by the buzzer is not muffled within the housing. The components within the housing are fully enclosed, except for the battery. The battery is mounted within an open sided battery case, which itself is mounted within the housing. The circuit, lacking an on/off switch, is disarmed and armed by removal and replacement of the battery in the battery case.
