Abstract
A plurality of sensor surfaces upon the touching of which an electric pulse is given off are arranged on a surface in an operating arrangement; the surface is surrounded by a frame whose surface is so shaped three-dimensionally as to provide the operator with a feelable indication of the position of the individual sensor surfaces.
Claims4
A control panel configuration consisting of a plurality of sensor keys arranged on a flat surface of the panel, each of said keys being responsive to a touch of a respective sensor key surface to produce an electric pulse, the sensor keys forming a smooth, closed surface with continuous parts of the control panel;
- the panel surface being surrounded by a frame with a surface configured in three-dimensions, the configuration of the frame surface including a sequence of undulations aligned with sensor key surfaces in a predetermined peripheral pattern providing an operator with a feelable indication of the position of the individual sensor key surfaces;
- and wherein
- the surface undulations of the frame have troughs which are of the same size as corresponding sensor key surfaces, the troughs lying alongside respective ones of the sensor key surfaces, and being positioned on the frame for receiving a human finger, thereby to guide the finger to a selected key surface;
- the panel surface being generally flat and being provided also with at least one rib for accessing sensor surfaces which do not lie at the edge of the panel surface.
