A SWITCH ASSEMBLY OF A MOBILE TERMINAL

摘要

PURPOSE: A switch assembly of a mobile terminal is provided to replace a reflective layer of a light guide film with a coverlay of a flexible circuit board, thereby reducing the thickness of a portable terminal. CONSTITUTION: A base film is flexible. A printing pattern is attached to the base film. A coverlay is attached to the surface of the printing pattern to reflect light. The coverlay is made of a white polyamide film. A metal dome(220) contacts the printing pattern. A light guide film is interposed between a keypad and the base film. The light guide film irradiates light onto the keypad.
