First Claim
Patent Images
1. A monolithic membrane switch comprising:
- a deformable substrate;
a first conductive layer;
a second conductive layer; and
,a layer for sensing actuation of the switch imprinted between the first and second conductive layers, where the layer for sensing actuation of the switch comprises;
a base resin;
a curable polymer; and
,a compound selected from the group consisting of carbon-impregnated powdered rubber, indium, indium-tin oxide, carbon powder, nano-carbon powder, and nano-silver powder, and combinations thereof.

Abstract
An combined monolithic electroluminescent lamp and membrane switch is manufactured by continuous printing. Graphic indicia is imprinted on deformable substrate. An electroluminescent lamp is imprinted on the graphic indicia layer and a membrane switch is formed on the lamp. The monolithic switch has a layer for sensing switch actuation by means including resistance change, capacitance change, or magnetic field change.
