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.Field of SearchPlural | |
