An analog joystick controller includes a handle shaft engageable with two yokes rotatably movable respectively about two perpendicular axes in response to tilting of the handle shaft. The yokes are respectively coupled to the wipers of two potentiometers, the resistance portions of which are fixedly connected to adjusting means manually movable for zero adjustments. Each yoke carries a pair of pivoting levers biased together into engagement with the yoke for movement therewith. Each pair of levers is associated with a control block which is manually movable between the levers to permit only one of them to move when the handle is moved from a center or home position, depending upon the direction of movement of the handle, for biasing the handle to its center position.
