Claim 1
Independent Claim
135 words
An educational toy comprising a plurality of interiorly illuminated modules each of which is interengageable with another module to form a stackable arrangement of modules, each module having one side that is disconnectable to provide simple access to its interior; a lamp socket and battery contact means located in each module to provide receptacles for a lamp bulb and a battery, respectively, first electrical connectors fastened to each module''s housing, means electrically connecting said socket and said battery contacts to said first electrical connectors whereby said lamp bulb and battery will be in series with the series circuit being normally open-circuited across said first electrical connectors; each module''s housing carrying second electrical connectors which are electrically shorted and are complementary with said first electrical connectors, to complete said series circuit when two modules are interconnected.
