A dome switch with multi contact points is provided to decrease the whole size of an electric device by using one dome switch to input a plurality of input signals. In a dome switch(250) with multi contact points, a printed circuit board(500) has a plurality of ground units(512). A multi ground terminal is arranged adjacently to the ground unit(512), and has a plurality of contact points elastically bent according to external force sequentially. And, a dome(251) surrounds external surface of the multi ground terminal to seal the multi ground terminal against the printed circuit board(500).
