Patent ID: 7220930

Claim:
A floor care appliance having at least one operational feature, comprised of: a suction nozzle; a handle; at least one electrical switch for controlling the operation of said at least one operational feature; and an electro luminescent light associated with said at least one electrical switch, said light and said associated electrical switch formed as a sheet comprising: a transparent substrate layer, said substrate layer allowing said electroluminescent light to pass therethrough; an electroluminescent phosphor layer, said electroluminescent phosphor layer disposed beneath said transparent substrate layer; a film layer disposed beneath said transparent substrate layer, wherein said electroluminescent phosphor layer is surrounded by a film layer; an inner capacitive dielectric layer disposed beneath said electroluminescent phosphor layer; a rear capacitive electrode disposed beneath said inner capacitive dielectric layer; a first encapsulating dielectric layer, disposed beneath said inner capacitive layer, wherein said first encapsulating dielectric layer surrounds said rear capacitive electrode; a second encapsulating dielectric layer, disposed beneath said rear capacitive electrode, and said first encapsulating dielectric layer; a first contact layer disposed beneath said second encapsulating dielectric layer; a first dielectric layer disposed beneath said second encapsulating dielectric layer, wherein said first dielectric layer surrounds said first contact layer; a second dielectric layer disposed beneath said first contact layer; a third dielectric layer disposed beneath said first contact layer, wherein said third dielectric layer surrounds said second dielectric layer; a second contact layer disposed beneath said second dielectric layer; a fourth dielectric layer disposed beneath said third dielectric layer, wherein said fourth dielectric layer surrounds said second contact layer; and a third encapsulating dielectric layer disposed beneath said second contact layer.
