A joystick mechanism (11) having a barrel rotator (21) is capable of multiple axis movement and multiple axis analog signal control. The joystick mechanism can be selectively spring centered on two axes, spring centered on one axis and frictionally positioned on the other, or frictionally positioned on both axes. A pair of switch mechanisms (29, 31), one for each axis of movement, selectably engage or disengage the respective centering spring mechanism. The analog signal generators are adjustable from the outside (25, 27) to provide biasing as required. |
