A stop tab mechanism for an particularly electronic organ of the type having a capture combination system. The stop tab mechanism includes an elongated stop tab having a front portion, a central portion, and a rear portion, a mounting bracket for the stop tab, spaced apart front and rear rests secured to the mounting bracket, guide means mounting the central portion of the stop tab for pivotal movement relative to the rests, including a spring urging the central portion of the stop tab into contact with the front and rear rests, and switch means operatively connected to the rear portion of the stop tab. The stop tab has a neutral position in which its central portion is seated against both of the rests and held in engagement therewith by the spring means, an on position in which the front portion of the stop tab is depressed, the tab pivoting about the rear seat to move its rear portion upwardly, and an off position in which the front portion of the stop tab is elevated, the stop tab pivoting about the front seat to move its rear portion downwardly. The spring means act to return the stop tab to its neutral position when the stop tab is released.

Stop tab for capture combination action systems used in electronic organs

A touch operated capacitive switch for altering electrical signals controlling the mode of operation of an electronic musical instrument. The switch comprises a thin laminate having a non-conducting lamina sandwiched between a conducting touch electrode and a conducting guard electrode, each electrode having an electrical connector for connecting the switch to alternating electrical signals having substantially the same phase and amplitude to reduce the capacitance between the touch electrode and points of ground potential located in or on the instrument for increasing the sensitivity of the switch. The switch is non-conductively secured to the instrument with the guard electrode facing the instrument, such that the capacitance of the switch may be altered by touching the touch electrode.
