ABSTRACT:
A stop control panel for an organ includes an elongated support panel on which modular groups of touch sensitive switches are disposed in pairs with an indicating lamp disposed between the switches of each pair, wherein the switches of the pair respectively actuate and de-actuate a given stop while the lamp indicates whether the stop is actuated. The touch sensitive switches are overlaid with a front surface layer through which the switches are operable by touch of the layer and through which the indicating lamps are observable when energized. The surface layer has printed thereon a plurality of color-contrasting outlines, each positioned to circumscribe a different pair of switches and associated indicating lamp to facilitate stop selection, the surface layer otherwise having a "dead front" appearance.
