摘要： A security tag for use in a retail environment comprises a main body housing circuitry, the circuitry comprising an oscillator module connected to a buzzer for producing an audible alarm and a switch, and an elongate lanyard extending from the main body and including a normally closed sense loop electrically connected to the circuitry. The switch comprises a transistor. The circuitry is configured such that if the lanyard is cut or otherwise damaged so as to create an open circuit in the sense loop the transistor switch triggers the oscillator module to emit the audible alarm.
