Abstract
An ornamental display assembly includes mechanical and electrical displays designed so that the electrical circuit that energizes the electrical display is opened by a mechanical plunger that operates under the influence of the mechanical display drive. A wind-up drive mechanism drives the mechanical display when a dual mechanical/electrical switch is turned to the 'on' position to simultaneously energize the electrical display circuit. When the wind-up drive mechanism winds out sufficiently to cause the plunger to extend a desired distance, the plunger forces open an electrical switch to break the electrical circuit, thus extinguishing the electrical display when the mechanical display ceases to operate.
