摘要
A switch substrate having a center terminal and an outer terminal exposed on the upper surface of the substrate, a dome member installed on the switch board to intermittently electrical contact between the central terminal and the outer terminal, and a tape installed over the dome member to cover the dome member A printed circuit board integrated surface mounting dome switch having an air path penetrating through the switch board in the area covered by the dome member among the area of the switch board is attached to the main printed circuit board surface. A printed circuit board is disclosed in which a corresponding hole is formed at a position corresponding to the air hole in the main printed circuit board as well. According to the present invention, when the dome switch for PCB-integrated SMT is attached to the main printed circuit board, the internal pressure of the dome switch is relieved so that the dome switch can be easily pressed, and also the dome switch is prevented from applying excessive pressure. Switch breakage can be reduced.
