Abstract
A control panel having a series of touch sensitive sensors mounted under a protective cover. The outputs of the sensors are effected by the presence of a human finger on the surface of the cover due to the capacitance of the human body with the earth. A microcomputer is used to distinguish intentional touching of the sensors from incidential contact with the panel, thereby making the control panel useful for controlling multiple functions from a single location.
