ABSTRACT:
A first pair of variable resistors are mounted on two opposite walls of a substantially rectangular outer casing in such manner that their rotary shafts coaxially extend through the walls and are attached to two opposite walls of a substantially rectangular inner casing. A second pair of variable resistors are mounted on two opposite walls of the inner casing in such manner that the rotary shafts are coaxial and that the axis of the shafts of the second pair of resistors is perpendicular to the axis of the shafts of the first pair of resistors. A connecting member links the shafts of the second pair of variable resistors. An operating shaft is rotatably mounted on and extends through the connecting member at right angles to the shafts of the first and second variable resistors and has a plurality of ganged additional variable resistors mounted on it, so that rotation of the operating shaft controls the additional variable resistors, while tilting of the operating shaft selectively controls the first and second pairs of resistors.
