Beschreibung
Zusammenfassung:	A method is for making an electronic device including forming a multilayer circuit board having a non-planar three-dimensional shape defining a membrane switch recess therein, the multilayer circuit board including at least one liquid crystal polymer (LCP) layer, and at least one electrically conductive pattern layer thereon defining at least one membrane switch electrode adjacent the membrane switch recess to define a membrane switch. The method also includes filling the membrane switch recess with a compressible dielectric material, and positioning at least one biasing member in the membrane switch recess.
