A keypad is disclosed for a portable electronic device. The keypad comprises an outer surface and a number of pressable keys (402). Associated with each key there is a pair of conductive contact points (501, 502, 611, 612, 620, 621, 622, 1106) separated from each other. A plurality of elastic domes (1103) is located next to the conductive contact points. For each pair of conductive contact points (501, 502, 611, 612, 620, 621, 622, 1106) there is an adjacent elastic dome (1103) having a concave side and a convex side, of which the concave side is at least partially conductive and directed towards the pair of conductive contact points. The concave sides of the plurality of elastic domes (1103) are directed towards the outer surface of the keypad.
