  • Patent number: 4023457
    Abstract: The stop control for an organ console comprises a panel including groups of touch sensitive switches disposed in pairs with an adjacent indicating lamp, wherein the switches of a pair respectively actuate and deactuate a given stop while the lamp indicates whether the stop is actuated. The switches of a pair are connected to set and reset terminals of a latching circuit which provides an output for energizing the indicating lamp and for controlling appropriate stop circuitry in the organ. The touch sensitive switches are disposed in groups according to the organ manual or function to which the corresponding stops pertain. A general cancel switch returns the various latching circuits to a reset condition. A transposer control circuit includes a plurality of switches and adjacent indicating lamps wherein the depression of a particular switch operates a latching circuit and resets other latching circuits associated with the transposer.
