L : L figure(+Y, +X only) directional operating type.
X : Cross direction of X and Y operating type.
Q : Square-directional 360°operating angle.
Z : In addition to omni-directional 360°operation, this type is3-dimensional coordinate operation by rotating knob in which apotentiometer is mounted on the body side of joystick, and this is
standard version, and also can be incorporated inside the rotating
knob(T type) on request.
R : In addition to square-directional 360°operation, this type is3-dimensional coordinate operation by rotating knob in which apotentiometer is mounted on the body side of joystick, and this isstandard version, and also can be incorporated inside the rotating
knob(U type) on request.
S : Special operating directions other than the above-mentioned types.
