ABSTRACT:
A drawknob for an organ is slidably mounted in an organ panel with one end thereof illuminated to indicate the state of the drawknob. A plate member is pivotally mounted relative to the other end of the drawknob and a spring device is provided for normally maintaining the plate member perpendicular to the longitudinal axis of the drawknob. One or more magnets are mounted on the plate member which are disposed between two magnetically operated switches. A restraint is provided adjacent the periphery of the plate member so that upon reciprocating movement of the drawknob in opposite directions the plate member will be pivoted to bring a magnet thereon into close proximity with one of the magnetically operated switches to operate the same.
