In a dom switch used in the key switch of a mobile terminal, the dom switch includes a PCB where a switch terminal is formed in an upper surface, a metal dom placed on the switch terminal and transmitting a signal to the switch terminal by an user' touch, and an optical guide bonding film scattering the light supplied from one side, fixing the metal dom to the PCB, and boned to the upper surface of the metal dom. Therefore, PET sheet is omitted, the thickness of the dom switch is reduced, and the cost of materials is reduced by reducing the number of members. The operation force of a key button is 5-25% less than the operation force of an existing key button |
