A panel-type wall system wherein each panel has a pair of electrically connected power blocks disposed adjacent the lower corners thereof. The opposed power blocks of adjacent panels are electrically joined together by a flexible electrical connector which plugs into adjacent power blocks. The power blocks and connectors define an electrical system which extends longitudinally throughout the series of connected panels. The electrical system is preferably a five-wire system to provide three different available circuits at each power block. Each power block is provided with several connector portions for permitting electrical power to be tapped therefrom. Different types of power-taps can be plugged into the power blocks. More specifically, the power-taps include a receptacle unit which can be selectively plugged into either or both sides of each power block, and a light-fixture plug which can also be plugged into each power block. Each of these power-taps has a simple manually actuatable switch associated therewith so the power-tap, when plugged into the power block, can be electrically joined to any selected one of the three circuits. The power-tap also provides a visual indication as to which circuit has been selected.

In a space-dividing wall structure formed from a plurality of prefabricated upright panels which are serially connected together, said wall structure including a prewired electrical system associated therewith and extending longitudinally therealong, said electrical system including a pair of power blocks mounted on each panel adjacent the opposite vertical edges thereof and multiple-conductor electrical cable means extending interiorly of each panel and connected between said pair of power blocks for defining at least two electrical circuits, said electrical system also including electrical connector means releasably connected between the opposed power blocks of adjacent panels for electrically connecting the adjacent panels together so that said two electrical circuits extend longitudinally throughout the plurality of serially-connected panels, each said power block having a connector portion associated therewith, and an electrical power-tap releasably joined to said connector portion of at least one power block, said power-tap having an inlet portion for electrical connection to said power block and an outlet portion adapted for supply of electrical energy to a circuit or device disposed externally of the wall structure, the improvement comprising circuit-selecting switch means associated with said power-tap for permitting the outlet portion thereof to be selectively electrically joined to either one of said two circuits as associated with said electrical system but not to both at the same time, said switch means including a manually movable switch member movably supported on said power-tap, said manually movable switch member being movable solely when the power-tap is disconnected from the power block, and said power-tap creating a plug-like releasable connection with the power block.
