Abstract

A security device for use in retail stores for the prevention of retail theft, which includes an alarm mechanism which generates an alarm signal in response to electrical power being applied through a switch mechanism. The switch mechanism is controlled by a signal provided by a closed circuit mechanism. Whenever a closed circuit condition is created, for example, by cutting the cable which mechanically connects the retail item to the security device, electrical power is applied to the alarm mechanism. Thus, if a battery is used to supply electrical power, such battery is only drained during closed circuit conditions, maximizing battery life.
