Abstract
A security device intervenes in the primary power input connection to an existing appliance. The user must set numbered thumbwheels to a correct numerical sequence preset through those same thumbwheels by the appliance owner before the device will connect the primary power to the attached appliance. Once the correct code is dialed in via the thumbwheels, a relay latches so that power is continuously available to the appliance until the primary power is lost as by disconnection of the appliance power cord for more than a short period of time. Reentry of the unique code is then necessary to operate the appliance. Labels are permanently affixed to the appliance to forewarn that it is not operational unless the correct code is entered. The attachment module is encased in potting compound to prevent bypassing of the power controlling circuits. The appliance is thus useless and of little value to a thief since it requires obvious disfiguring of the appliance to remove the combination lock assembly and/or the labels.
