Abstract (en)
A dome assembly for use in a keyboard assembly of an electronic device is provided. The dome assembly includes a deflectable dome shaped element (52) having a concave surface terminating at a periphery (56) and a number of elevating members (58) disposed on the element adjacent the periphery and protruding away from the concave surface. The elevating members serve to space the periphery from a mounting surface. The element is movable between an undeflected position and a deflected position.
