Beschreibung
Zusammenfassung:	An electronic device includes (45) a multilayer circuit board (53) having a non-planar three-dimensional shape defining a membrane switch recess (52) therein. The multilayer circuit board may include at least one pair of liquid crystal polymer (LCP) layers (50,51), and at least one electrically conductive pattern layer (46,47) on defining at least one each LCP layer (50,51), each membrane switch electrode adjacent the membrane switch recess to define a membrane switch. The electronic device may further include a compressible dielectric material filling the membrane switch recess. The electronic device may also include at least one spring member within the membrane (56) switch recess.
