Abstract
A pilot valve having a universally tiltable joy stick further includes a cam attached to said joy stick and movable therewith. A plunger is selectively movable into engagement with the cam for latching the joy stick in a selected one position. Fluid is supplied to the plunger for developing a force acting thereon to move the plunger into engagement with the cam. The fluid force is eliminated and the plunger disengaged from the cam to delatch the joy stick.
