Abstract: A voltage surge suppression device is disclosed requiring no modification to electrical outlets for its installation. The device includes prongs for mating with a receptacle of a given electrical outlet, such as a wall outlet or a power strip. The device places its voltage surge suppression elements inside a cube-like housing sufficiently modular for easy removal and replacement and sufficiently small in size whereby allowing plugs of electrical appliances to be mated with the receptacles immediately adjacent to where the voltage surge suppression device is connected. When the need arises to replace the device, the replacement cost does not include the costs for circuit elements such as receptacle contacts, additional prongs, and an entire power strip.

Abstract: A power center for using ON-OFF switches to control power availability for individual receptacle outlets is disclosed. The molded-in receptacle apertures and podded contact strips provide significant space, cost and efficiency improvements over existing power centers which use stand-alone, off-the shelve receptacle parts.
