    摘要: This invention is directed to a surface-mounted dome switch for use in an electronic device. The switch may include a dome having a conductive inner surface operative to create an electrical path between adjacent conductive pads of a circuit board. The dome may include a tab extending away from the periphery of the dome such that the tab is parallel to the circuit board when the dome is mounted to the circuit board. The tab may be mounted a pad on the circuit board using SMT, in the same manner that any other electronic device component would be mounted. In some embodiments, a raised edge may be inserted underneath the dome to increase the travel required to actuate the dome. The increased travel may provide a more pleasing user experience.
