Abstract:
A normally closed dome switch comprises a printed circuit board including a switch trace having first and second contact areas electrically insulated from one another, and a conductive switch dome having a central portion spaced from the printed circuit board and a plurality of contacting portions extending from the central portion such that each of the first and second contact areas is contacted by at least one of the contacting portions when the switch dome is unpressed such that the unpressed switch dome forms a closed switch between the first and second contact areas. The switch dome is resiliently pressable to urge the central portion toward the printed circuit board and pivot the contacting portions about a corresponding fulcrum to remove the plurality of contacting portions of the switch dome from contact with at least one of the first and second contact areas to open the switch.
