摘要： A keypad has a substrate carrying an array of sense elements arranged to change state in response to keypad operation, a flexible cover disposed above the substrate and having an exposed surface defining an array of independent key regions, with combination key regions defined in interstices between adjacent independent key regions, and an array of discrete snap elements extending between the cover and the substrate and spacing the cover from the substrate.
