Abstract: A pedal board for musical instruments. Pedal mounting, guide, and electrical switch mechanisms are provided in a pedal board for an electronic organ. Each pedal is mounted by a cylindrical pin attached to the back end of the pedal and to the base of the pedal board by an interference fit. A similar, guide pin is attached to the front end of the pedal by an interference fit. The guide pin fits loosely in an aperture which limits lateral movement of the pin and, thence, of the pedal itself. The lower end of the guide pin actuates an elastomeric electric switch when the pedal is pressed down. The elastomeric electric switch is mounted on a printed circuit board, and includes a chamber having a bell-shaped wall attached to a support strip by weakened edges and enclosed at the bottom by a diaphragm carrying a conductive element. The conductive element shorts contacts on the printed circuit board when the chamber is compressed by the guide pin. Pedal board tension and resiliency is provided by the mounting pin.

Abstract: A rocker switch, particularly for selecting voices in an electronic organ. A translucent tab is pivotally mounted at its center on a printed circuit board such that when the tab is pressed at either end, it actuates a respective elastomeric electric switch also mounted on the printed circuit board. A lamp is releasably mounted on the printed circuit board through an aperture in the back thereof by a twist-lock mechanism. A petal-like reflector and shield is disposed behind the tab for reflecting light from the lamp through the tab while blocking stray light and minimizing heat buildup. Elastomeric electric switches are positioned on the circuit board by pins and held in place by the pressure of the petal-like reflector, which is attached to the circuit board by plastic rivets. The tabs snap onto pivot points integrally formed as part of a rocker bar that includes the petal-like reflector.

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.
