A switch is mounted in the case and has operative and inoperative positions and assumes an operative position when the switch is tilted from the vertical beyond a predetermined angle. An alarm is carried by the case and electronic circuitry is connected to the tilt switch and to the alarm for actuating the alarm when the tilt switch is moved from the vertical beyond the predetermined position.
