Electromagnetic friction lock for a dual axis control devices

A control device for operating a plurality of hydraulic valves of a machine having a prime mover, said control device comprising:

• a plurality of actuator members, each one for engaging one of the plurality of hydraulic valves;
• a plurality of springs which bias the plurality of actuator members into neutral positions;
• a seat having a first and second portions moveable with respect to each other and forming a cavity;
• a handle having a sphere received within the cavity of the seat, wherein the handle produces movement of at least one of the plurality of actuator members when the sphere is pivoted within the cavity;
• an electromagnetic coil operatively coupled to the seat and which when energized produces a magnetic field that causes the first and second portions to be attracted toward each other which increases friction between the sphere and the seat;
• and
• a control circuit for applying an electric current to the electromagnetic coil whenever the prime mover is turned on and wherein the electric current is disconnected from the electromagnetic coil when the prime mover is turned off.
