RADIO SWITCH IN A MOBILE PHONE, ESPECIALLY CONCERNED WITH UTILIZING THE INTERNAL SPACE OF A REAR CASE TO A MAXIMUM AND REDUCING A FAULT RATE DUE TO THE FALL OF A MOBILE PHONE TO A MINIMUM
PURPOSE: A radio switch in a mobile phone is provided to maximize the utilization of the internal space of a rear case, to minimize a fault rate due to the fall of a mobile phone, and to improve durability. CONSTITUTION: A radio switch, installed on the side of a rear case in a mobile phone, consists of a metal dome switch part(10), a support bracket(20), and a button(30). A switch frame(14) having a terminal pattern(12) on an LCD FPCB(121) is formed with an insert-molded terminal part(15) in a single unit. The metal dome switch part(10) is formed as a metal dome(16), connected with the terminal pattern(12) by the pressurization of the button(30), is loaded on the terminal pattern(12). In the support bracket(20), a fixing chip(22), inserted into and fixed to a main circuit substrate(111), and a support chip(24), supporting the rear surface of the terminal part(15), are formed. The button(30), at which a protrusion(32) pressurizing the metal dome(16) is formed, is installed at the rear case(110).
