Abstract:
A dome contact (32) for pushbutton switches (300) includes a diaphragm (33) having a reversible dome portion (331), and a bump (34) projecting from a central portion of a convex surface of the dome portion. A method for fabricating the dome contact includes steps of: providing a diaphragm formed by injection molding or screen printing; and forming a bump on a central portion of a convex surface of the diaphragm via thermal extrusion laminating technology of rapid prototyping technology.
