ABSTRACT:
The Merchandise Theft Deterrent Sensor deters theft of display merchandise by implementation of a sensor directly into an anti theft detection system. The Merchandise Theft Deterrent Sensor is attached directly to goods through the use of a pair of specially designed adhesive surfaces; one surface in the form of a peripheral rectangular window surrounds as second surface which is directly attached to a centrally located, moveable piston and electrical membrane switch assembly. The piston membrane switch assembly activates an alarm means if motion on the order of two thousandths of an inch occurs. The Merchandise Theft Deterrent Sensor is assembled in a small rectangular molded plastic container, wherein the closeout lid of the container is flexible to enable in-place checkout of the sensor by minor depression of the lid to activate the moveable piston and electrical membrane switch assembly. Any number of the Merchandise Theft Deterrent Sensors can be connected in series to provide protection against theft of multiple pieces of merchandise.
