ABSTRACT:
A manual controller for tripping or actuating switches used to energize j motors associated with a vehicle-raising or lowering mechanism, e.g a missile launch trailer or mobile home. The controller uses the "joy stick" principle, wherein the human operator moves an upstanding control rod or stick in any one of four directions to actuate selected ones of the switches. In fact the controller comprises two independently-movable joy sticks; one joy stick controls the "vehicle-raise" action, and the other joy stick controls the "vehicle-lower" action.
