Abstract: A disabling device for electronic circuits includes a female connector with an easily accessible front surface and an inaccessible rear surface. A large array of contact pairs are found in the female connector. A predetermined number of input/output wires join the female connector in series with the circuit across randomly selected contact pairs in the array. A number of non-functional dummy wires also connect in the array to further complicate the non-uniform connection pattern. When a male connector containing an internal arrangement of jumper wires is inserted into the female connector, the jumper wires short across the proper contact pairs and close the circuit. Subsequent removal of the male element again opens and disables the circuit.
