A touch-sensitive selection panel structure for a vending machine including a pressure-sensitive membrane-type switch contained between first and second polycarbonate panels comprising the display panel of the vending machine. The touch-sensitive switch configuration is totally transparent to visible light. A product selector window array on the first polycarbonate panel is back-illuminated from within the vending machine with images of the vendable products available, for display in the selector windows on the front face of the vending machine display panel. The images are provided on the back face of the second polycarbonate panel within the vending machine and illuminated from behind in order to project the names and product logos through the membrane switch, and the first polycarbonate panel for viewing by a potential customer. The membrane switch contacts are easily actuatable by merely pressing on a flexible product window area defined in the first polycarbonate sheet, which causes selected membrane switch contacts to close and initiate the vend of a corresponding product. In an alternative embodiment, the membrane switch is replaced by discrete touch-sensitive switches disposed in portions of each of the window areas.

1. A touch-sensitive selection panel structure for a vending machine for initiating the vend of related products comprising: (a) a first sheet member having transparent areas thereon defining touch-sensitive product selection windows, said first sheet member defining the obverse face of said selection panel; (b) pressure-sensitive switch means disposed directly behind and contiguous to said first sheet member, said switch means being responsive to pressure applied to said product selection windows to generate electrical signals for initiating the vend of related products, said switch means being transparent to visible light; (c) a second sheet member secured to said first sheet member by an adhesive coating and having transparent areas thereon disposed behind and contiguous to said switch means; and (d) pocket means between said first and second sheet members for removably containing said pressure-sensitive switch means, said adhesive coating being relieved in area behind said product selection windows to define said pocket means. 2. The panel structure of claim 1, further comprising slot means in said first sheet member in communication with said pocket means, said pressure-sensitive switch means being insertable into and removable from said pocket means through said slot means. 3. The panel structure of claim 1, further comprising slot means in said first sheet member in communication with said pocket means, said pressure-sensitive switch means being insertable into and removable from said pocket means through said slot means. 4. The panel structure of claim 1, further comprising product-identifying indicia disposed behind said second sheet member in alignment with said windows, whereby said indicia may be viewed through said windows. 5. The panel structure of claim 4, wherein said product-identifying indicia comprises projection transparencies secured to the back of said second sheet member. 6. The panel structure of claim 5, wherein said transparencies are secured by adhesive. 7. The panel structure of claim 5 in combination with a visible light source disposed behind said second sheet member for projecting images of said indicia through said windows. 8. The panel structure of claim 1, wherein said pressure-sensitive switch means comprises first and second flexible films separated by an intermediate plate having openings therein aligned with said windows, one of said flexible films having discrete conductive areas thereon aligned with said openings, the other of said flexible films being conductive across the entire surface thereof, whereby pressure applied to said windows presses conductive areas of said first and second films together through said openings generating said electrical signals. 9. A method of making a display panel for a vending machine including a sign panel portion for displaying logo related to at least one product to be vended and a touch-sensitive selection portion for selectively initiating the vend of selected products, comprising the steps of: (a) providing first and second transparent sheet members including said sign panel portion and said selection portion; (b) applying coloring to both said portions of said first sheet member to define said logo in said sign panel portion and discrete transparent windows in said selection portion corresponding to the products to be vended; (c) coating at least one of said sheet members with adhesive in substantially all areas except the area behind said transparent windows in the provision of a pocket for containing a touch-sensitive switch array; and (d) securing said first sheet member to said second sheet member with said adhesive. 10. The method of claim 9, comprising the further step of inserting a touch-sensitive switch array into said pocket. 11. The method of claim 10 wherein an opening is provided in said first sheet member just above said selection portion and said switch array is inserted into said pocket through said opening. 12. The method of claim 9, wherein said adhesive is applied to the back of said first sheet member. 13. The method of claim 10, wherein said adhesive is applied to the back of said first sheet member. 14. The method of claim 11, wherein said adhesive is applied to the back of said first sheet member.
