  • Joystick with spring disconnect
    Patent number: 4857881
    Abstract: A joystick mechanism having a barrel rotator 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, one for each axis of movement, selectably engage or disengage the respective centering spring mechanism. The analog signal generators are adjustable from the outside to provide biasing as required.
