Teaching light

Claim 1

An electrical teaching apparatus comprising: a substantially rigid electrically insulating base member; a first electrically conducting layer partially covering a face of said base member; an electrically conducting contact member on said base member, said contact member being spaced from and always out of contact with said first electrically conducting layer; a source of power coupled between said contact member and said first electrically conducting layer; an indicator light coupled in series circuit with said power source, said first electrically conducting layer and said contact member; a question and answer member adapted to overlie said first electrically conducting layer and to engage said contact member, said question and answer member including an electrically insulating bottom layer control sheet which has at least one aperture therein; a second electrically conducting layer on the upper surface of said control sheet and overlying said at least one aperture; an upper electrically insulating question sheet overlying said second electrically conducting layer and having at least one question imprinted thereon and indicia for selecting an answer; said control sheet and question sheet being permanently coupled together at least along an edge thereof in registration with each other and with said at least one aperture in registration with a correct answer indicia, and defining at least one openable flap portion between said control sheet and question sheet, said contact member being passable through said openable flap portion for electrically contacting said second electrically conducting layer; whereby when pressure is applied in the area of a correct answer indicia, an electrical circuit is completed to said indicator light from said power source, through said contact member and through said first and second electrically conducting layers which contact each other via said pressure in the vicinity of said at least one aperture in said control sheet.
