Electroluminescent lamp membrane switch

摘要

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.
