Abstract

A keyboard is protected against the environment by a moulded synthetic rubber sheet 18 which bears key areas 21 demarcated by ribs 20. The sheet is sealed on to a housing of the keyboard. Under each key area is a switch formed by two printed circuits 17 and 13 adapted to make localized contact through one of an array of apertures 16 in an insulating sheet 15. When a key area is pressed lightly, the corresponding symbol is displayed on an associated luminous display device but the data is not keyed into the working register. This occurs when heavier pressure operates a second switch such as a 'pancake' switch with snap action, of which there may be one under every key area or a smaller number acting collectively for all areas. <IMAGE>
