ABSTRACT:
An electrical control device having a joystick or lever manually movable in the X and Y directions to actuate a pair of electrical components having respective rotatable shafts. The controller includes a housing having a top cover provided with an opening through which the lever extends. The lower end of the lever is pivotally mounted in a socket on the bottom of the housing and a ball joint is carried by the lever intermediate its ends. The ball joint is pivotally coupled to a control plate shiftable in the housing beneath the top cover, the plate being biased into an equilibrium position by a number of leaf springs normally engaging respective side margins of the plate. The plate has a pair of slots in its lower surface, the slots being mutually perpendicular and vertical projections on the outer ends of a pair of bell cranks are shiftably received within respective slots in the plate. The bell cranks are coupled to the rotatable shafts of respective electrical components so that, when the plate is moved in any one of a number of different directions upon manual movement of the lever, one or both of the rotatable shafts of the electrical components are rotated to actuate the components.
